Horticulture Hotline 12/29/2025

The fifty degrees drop in temperature a couple of weeks ago certainly put a hurting on lantana and hibiscus and other tender plants; however, citrus and bottlebrush seemed to survive ok. If you can wait to cut the damaged plants back, the damaged tissue will help to insulate the plant from further damage, and the nasty looking foliage will help to keep the heat of the Earth near the crown of the plant – protecting the plant.

 

Moles are very active this time of year. Moles do not like vibration, so when you are mowing the grass less often, they enjoy the lawn area even more than usual! Like the way fire ants do not like being disturbed and will find a tree ring or mulched area off the grass to build their mound. The mole’s food is deeper in the soil, so they must tunnel more to find it. The grass is not actively growing, so the grass does not recover from the damage as quickly in the winter.

 

Here are a few New Year’s Resolutions for the Gardener:

 

Take care of the gardener, so the gardener can garden! Doctor visits are important! Preventive medicine is the best medicine – just like your yard. A blood test can tell a doctor a lot about your health, so you can keep on gardening. Dentists, ear doctors, and eye doctors are important as well. You want to be able to see insects and diseases – and read the Horticulture Hotline (shameless plug). Hearing the sounds of the Lowcountry and “The Garden Clinic” radio show on WTMA from 10:00 – 11:00 AM on Saturdays (another shameless plug) will help you garden. Gardening with a sore tooth or gums is never fun.

 

Take a soil test (like a blood test for people) so you know what your soil needs are and amend the soil accordingly. I have been doing this for myself on landscape jobs since the late 1970’s and for other people since the early 1980’s. When people return to Possum’s Landscape and Pest Control after following our prescription for their lawn, they are happy, happy, happy. It is amazing how your grass will respond with a little tweaking of nutrients. A custom program is the best way to go, so you have a yearly calendar of what to apply and when to apply it. What is the old saying, “if you write down a goal, your chances to achieve it go way up.” A custom program will give you a step-by-step formula for an awesome yard in 2026. 

 

Go through all the old products you have in your garage and identify why you purchased them to begin with and if they are products that can still be used.  This will save you money and make room for new and improved products. If the products are old and you are not able to identify them, there are several recycling centers in the area that accept household hazardous wastes.

 

Manage winter weeds now while they are young. The recent warm spell really made the winter weeds visible. The bigger they get the harder they are to control. If you kill them now, you will not have to pull out the mower to mow the weeds as they grow and you will kill them before they produce seeds for future weeds.

 

Treat fungus proactively – you will save money. There is a lot of diseases out there waiting for conditions to get right for another attack. Our ground stays warm enough for grass to absorb nutrients or systemic fungicides. Keep your eyes out for the next warm spell because the large patch / brown patch we had in the fall will explode again.

 

Use wetting agents this year.  Wetting agents have been shown to save approximately 30-60% of water consumption for a yard.  A huge savings on your water bill.  By watering less, you will have less fungus problems and save money by not having to buy as many fungicides or water. At Possum’s we have noticed that a lot of people that use wetting agents save even more water because they are more in tune to their watering and their water bill. They are saving more like 80%, so if their water bill was $100.00 per month now the bill is only $20.00. Huge savings and water bills are usually more than $100.00. There are many other benefits to using wetting agents! Your roots will grow deeper, and you will be able to capture more nutrients, so you will get more out of your fertilizer.

 

To conserve water, it is time to get that hose that leaks at the faucet a new gasket. Check your irrigation. Are all the zones necessary or can you turn some off? Shrubs and trees should be established after one year or sooner. Are the heads spraying the way they were intended to spray?  If you need help, get the irrigation person over now before the spring rush.

 

In 2026 try to remove fertilizer and other control products from hard surfaces like driveways, sidewalks, pool decks, and streets before these products are washed into the storm water.  This will help protect the beautiful area in which we live.  Since a lot of storm water ends up in our marshes and waterways, this will also help protect our natural resources that we use for recreation (oysters, crabs, shrimp, and fish), food (oysters, crabs, shrimp, fish), and jobs (oysters, crabs, shrimp, and fish). You will also avoid that nasty staining. In South Florida and in other parts of the country, there are laws telling people when they can fertilize. Let’s be responsible gardeners, so we avoid these laws.

 

Buy a 100 pack of disposable nitrile gloves.  These things are great!  You can use them when handling control products and fertilizers, when changing the oil in your lawn mower, while taking down your Christmas tree to keep sap off your hands, while painting or taking out the trash, cleaning, picking up after your dog and yard work….  These gloves are very inexpensive and can save you lots of hot water while trying to remove things from your hands.  These gloves are also good at keeping the human scent away from mole, mice, and rat bait.

 

In 2026, add organic matter to your lawn and beds.  Organic matter will also help you lower your water bill while adding many other benefits to your soil.  Cotton Burr compost has been improving Lowcountry soils with great results over the past 20 years.  If you want to see for yourself the benefits of cotton burr compost, measure a 100 square foot area in your turf (10 feet x 10 feet) and spread one 2 cubic foot bag. Check out the progress over a month. Many people feel their fungicide, water, and fertilizer use has gone down after using cotton burr compost.

 

To combat weeds, plan to put out preemergents in your lawns and beds according to product label.  This will make your life a lot less stressful, and your yard will look a lot better without weeds.  If time is a big issue, consider buying a year’s supply of products now, so you will have the product in hand when it is time to apply. 

 

In 2026, always apply product according to the label’s directions.  No more, “if one ounce is good….two ounces will be real good”. Many of our fire ant products, less is better. On the pest control side of our business, roaches and rats can be repelled with too much product instead of contacting the product and dying. Follow the label that has cost the manufacturer millions of dollars to get approval from the EPA, and you will have better results. This will also save you money - not to mention the product label is Federal Law. 

 

For those pet owners out there, whose animals have a history of flea problems, be proactive by applying growth regulators. Nyguard, D-Fense NXT, or Precor 2000 applied every three months, should keep your pet free of fleas. Rotate products with different active ingredients.

 

Always mow the grass with a sharp mower blade and prune the bushes with sharp pruning blades.  You will have cleaner cuts and less chance of disease. Take your mower to the shop for a tune-up before the spring rush. If a gardener needs surgery, you will prefer a sharp scalpel for a clean cut, not an old dull blade.

 

Read a good book about gardening.  Reading is how we learn and it will motivate you as a bonus.  Picture books are fine. Take walks around our beautiful city for gardening ideas.

 

Plant a plant for a pollinator – like milkweed, butterfly bush, bottlebrush, bee balm, salvia …

 

Happy New Year!

Tis The Season

 

                                            Deck The Halls?
                                            Nice white Sasanqua Camellia 
                                             Poinsettia - Notice it is the leaves that are red

                                                     Large Patch Fungus
                                                     


Horticulture Hotline 12/14/2025

By Bill Lamson-Scribner

 

Ok, I get it. The mid-seventies in late November. It is Charleston and why we love it. Apparently, the mole crickets, moles, fire ants, and large patch fungus love it as well. The rat managing products have been flying off the shelf at the three Possum’s stores too. I have seen more fire ant mounds this fall than I can ever remember seeing! We (Possum’s) sell 25-pound bags of fire ant bait that cover over 16 acres per bag. I never remember selling so many of these bags this late in the season.

 

I thought about sending out an alert type Horticulture Hotline (I think it would have been only the second one in 36 years of writing this column); however, I did not want to cause any hysteria around the Holiday Season. I have been writing about large patch since early August, so hopefully, some of you were saved from the disease! Driving around the Lowcountry, it is amazing how many yards have been damaged. The cold weather this week will slow it down for a few days; however, when it warms back up, the disease will be active again. Strobe Pro G and T-Methyl are two good systemic fungicides to rotate to manage this disease.

 

Sweating while you bring in the Christmas Tree – ah the Lowcountry! Here are a few holiday gift ideas for the gardener.

 

Does it seem like your free time is spent doing maintenance yard work around the house?  You work long hours all week, and then on the weekend instead of spending time with your family, shopping, on the boat, on the golf course, hunting, etc., you spend it pushing a lawn mower inhaling that blue smoke?  Give yourself a lawn care company for a year and enjoy your time off doing what you like to do.  You can still spend time in the yard doing specialty things; just get rid of the mowing, edging, control product applying and blowing.  Also consider hiring professionals to do other house maintenance (power washing, painting….). The gift of free time is awesome!  If you enjoy working in the yard, a custom program from Possum’s based on your soil test can give you a plan for success.

 

Plan a trip to a local public garden (for example Magnolia Plantation, Middleton, Boone Hall, Drayton Hall, Charles Towne Landing, the many county parks – be sure to take in the Holiday Festival of Lights at James Island County Park, or Hampton Park) and get ideas for your own landscape.  This also makes for a wonderful day with the family.  You can take a picnic lunch and make it a full day enjoying the beauty of the Lowcountry. Many of these parks you can buy a yearly pass for just a little more than a onetime visit and enjoy the park throughout the year. The gift of visiting an ever changing and special place to the Lowcountry is awesome! Since you live in the Charleston area, you probably have out-of-town visitors, so you will have a great place to take them for the day.

 

If you would like to take a road trip, travel to Brookgreen Gardens by Myrtle Beach, or Riverbanks Zoo in Columbia. You can also give a gardener a trip out of the area for a long-distance gardening adventure.  Calloway Gardens in Atlanta, Longwood Gardens in Pennsylvania, The National Arboretum outside of Washington, D.C., The Redwoods in California, or any other garden throughout the United States…. or anywhere in the world!

There are some awesome gardens!

 

Give a gardener a gift certificate for a future Home and Garden Tour event.  There are great tour events throughout the year in areas all over the Lowcountry.  Kiawah, Seabrook, Daniel Island, City of Charleston, Summerville, Mount Pleasant all have different garden tours.  If you want to go on a road trip, Savannah and Beaufort also have garden tours. There is a great Plantation Tour in the Georgetown area that I have been on several times. Seeing what other landscape ideas do well in the Lowcountry is awesome!  

 

Give your gardener a membership to one of the many clubs or societies in the Charleston area. The Rose Society, The Charleston Horticultural Society, The Native Plant Society, The Camellia Society, The Koi Fish Club and Daylily Society just to name a few.  I have attended and spoken at many of these club’s lectures.  They are all very informative and are passionate about their interests, willing to help newcomers, and provide different community projects to improve the Lowcountry.  I have run into many old friends and have made many new friends at these meetings. Gaining knowledge about a topic you are interested in is awesome!

 

Books (different Universities sell very informative books at very good prices), quality hand tools (especially pruners and pruning saws), decorative pots, cuttings from your garden, a plant, tree, or bulbs, or something you have canned from your garden, all make great gifts!

 

A gift certificate to any of the local garden centers or nurseries makes an excellent choice for the garden enthusiast.   They are bound to find something they want, and you do not have to worry about whether they will like the gift. For the most part free and easy parking. Now that is awesome!

 

Happy Holiday Season! Are you ready for New Year’s Resolutions for a gardener?

Two Diseases Attacking Our Turf

 

                                             Strobe G Preventative 

                                              St. Augustine     Strobe G     Preventative
                                            Large patch fungus attacking the whole yard


Horticulture Hotline 11/23/25

By Bill Lamson-Scribner

 

The disease that attacks the turf while it is going into dormancy (fall) or coming of dormancy (spring) has exploded on the Lowcountry’s turf. While walking and driving around, it seems that large patch has invaded the Lowcountry in a big way. As the cooler weather comes, the daylight hours shorten, and the grass growth rate slows down, large patch fungus began to show up in our lawns. Proving once again, the Lowcountry is the hardest place in the world to grow grass and why it is so important to have a program for your lawn. Do you see areas of your grass that are brown when other parts are green? Be sure the areas that are brown are your turfgrass and not summer annual weeds (crabgrass...) that have died (doubtfully if a reader of the Horticulture Hotline).

 

Large patch disease is always present in the soil; it just manifests itself when the environmental conditions are right and your grass cannot outgrow the damage. Without any sustained cold temperatures, this disease is slowly spreading across lawns as the temperatures that favor its growth keep coming into play. This prolonged fall is great for outdoor activities like visiting local plantations, fishing, boating, golfing, shopping, and working in the yard; however, the temperatures are also perfect for these diseases to develop and spread. The grass is not fully actively growing (not mowing as much) and it is not fully dormant (brown), so these are perfect conditions for the disease to attack. Disease needs to be present (in the soil always), susceptible host (your grass), and the right environmental conditions (been nice weather for us – a slow transition is not good for the grass). These three conditions make up the disease triangle.

 

Large patch fungus likes wet, heavy thatch, improper nutrition, and/or compacted soils.  Culturally you need to manage your irrigation system, raise any low areas, and correct drainage problems.  Reducing thatch (at Possum’s we have a great organic granular product for controlling thatch), maintaining proper fertility levels, and aerating to alleviate compaction, will also help control large patch. A healthy turf (following soil test derived feeding schedule) with a soil with a lot of biodiversity (use of cotton burr compost, SeaHume and other organics) has been shown to help manage this disease.

 

As your grass is going into dormancy and the temperatures begin to cool at night, large patch is ready to attack your grass. Large patch will go inactive when the temperatures get very cold; however, it will become active again when the temperatures favor the disease. If you have discolored areas in your yard that appear to be a disease, check with someone that knows. Even if it is during a cold phase and the disease does not appear to be active, you can still put out a systemic fungicide for protection if you see that the weather is warming. Our soils do not get so cold that the plant will not absorb the fungicide with its roots. Remember treating a fungus with a systemic fungicide is like getting a flu shot – you do it preventatively before you have the disease. If it is too late to use it preventively, when you want the disease to stop spreading, you can use the fungicide curatively. Treating preventatively requires less product and less frequent applications of fungicides.

 

A good granular one-two punch control strategy is T-Methyl and Strobe Pro G (both systemic fungicides that get into the plant). Reliant is a good organic spray that is a good rotation partner. Use these products in areas where you have had large patch previously at the preventive rates and intervals recommended on the labels. Be sure to use T-Methyl with Strobe Pro G, so you are switching chemistry classes and modes of action. Good control early on can help avoid flare ups in the spring also. If you do not manage the disease, the grass will thin, and weeds will take over. Two pictures show the use of Strobe G preventatively and the other picture shows the large patch fungus.

 

If you are growing ryegrass this fall, the conditions have been perfect for Pythium as well. Pythium is a disease (not a fungus), and it thrives in hot, humid, poorly drained, and overwatered areas. Warm humid nights, grass blades that stay wet for long periods of time (have you ever seen someone using a dew whip on a golf course green to knock the dew off so the leaf blades dry quicker?), and wet warm weather will make this disease explode. Warm nights and foggy mornings also make ryegrass susceptible to this disease.

 

Pythium travels super-fast through an area and can wipe out large areas of turf overnight. Mowing, rolling, tarps on infields of baseball fields, and surface water drainage will spread this disease rapidly. In 36 years of writing this column, I have never written about this disease; however, the environmental conditions have been so perfect, I figured I better write about it.

 

Sometimes in the morning, you will see something that looks like cotton candy or cobwebs on the turf areas. The grass can also appear to be greasy. Like any disease it is best to treat preventatively when you see favorable environmental conditions in the forecast. Strobe, Reliant, and Subdue (Mefenoxam) are good control products to rotate for control of this very fast-moving disease.

 

What an awesome Lowcountry Fall! James Island County Park’s Holiday Festival of Lights? Soil Test and Fertility Program from Possum’s? Rats? Roaches? Fleas? Tree pruning and trimming? Transplant shrubs or trees? Edge bed lines and sidewalks for the last time for a while? Rake or blow leaves? Clean out beds that have an accumulation of mulch, leaves, or pine straw? Mulch your beds after leaf drop? Moles?

 

Always read, understand, and follow product label. The product label is a Federal Law.

Christmas Tree and More

 










Horticulture Hotline 11/23/25

By Bill Lamson-Scribner

 

Another year has almost gone by. What a year! Army worms, lots of high tides (salt issues), mosquitoes, strange rain (or lack of rain) patterns, and moles. With the dry spring, we had very little, large patch fungus – a nice change! With the recent prolonged mild temperatures, large patch fungus and pythium (on rye grass) have been hot topics.

 

This week I started seeing tents going up in parking lots, so I figured it was time for the yearly Christmas tree article.  

 

The Holiday Festival of Lights at James Island County Park is always a must see this time of year. The light show is a tradition with my family. The lights, the train, hot chocolate, smores (if you listen to “The Garden Clinic”  you know I’m not a fan of smores -sticky messy-, but everyone else seems to be), the walking trails with lights, the big sand feature, music, gift shop, and oh yeah, Santa. If you are a kid, does Christmas still seem like it takes forever to get here? It sure comes up quickly to me now that I’m an old geezer! 

 

I wanted to get this yearly Christmas Tree article out, so you could make plans to go to a local Christmas Tree Farm, find a local source for a cut tree, or use a live tree that you could use in your landscape after the holidays, if you were so inclined.

 

After Thanksgiving, many of you will be searching for a Christmas tree.  If you are going to buy a cut tree, consider buying it from a local business that is here year-round like an independently owned garden center.  If you buy it from a tent, or a temporary site, look for one that is run by the Exchange Club, Optimist Club, Rotary Club, a local church, a local school club, a local landscaper, or another local organization.  Many local organizations that sell trees give a portion of the profits to local charities such as Camp Happy Days or Ronald McDonald House.

 

There are some people from out of state that set up tents in grocery store parking lots. Many of them bring their employees with them. They take their profits out of state when they leave. If you support our local businesses, then you keep our money in our local economy and maybe save a local job. It is very important to always keep profits local, especially these days with so much going to online merchants that do not hire people or spend money locally.

 

Many of the local garden centers offer great Christmas gifts along with trees this time of year.  They have purchased many seasonal items that would be a great present for anyone. Gift certificates are usually available for the hard-to-shop gardeners. Shopping at a garden center is a great way to avoid long lines.  The parking is free and plentiful at this time of year. A nice pot, potting soil, wetting agent, and fertilizer would make a great gift.

 

Have you ever considered a live tree? Different Hollies (right now you can tell the females with beautiful berries), Eastern Red Cedar, Little Gem Magnolias, Osmanthus, Deodara Cedar and many more make great trees and after the holidays you can plant them in your yard instead of throwing them to the curb. Leyland Cypress have been removed from this list due to their disease issues.

 

Local tree farms are also an option. A ride in the country is always a good family event (young children, “how much longer will it take to get there?”). Picking out your own tree is fun for the whole family and usually involves hot chocolate and hayrides. You know you are getting a fresh tree when you cut it yourself. 

 

If you go with a traditional cut tree, make sure it is in water at the place you buy it (unless it is coming fresh off the truck), and make sure it stays in water until you take it to the curb after the holidays.  Once you bring the tree home, cut an inch off the bottom of the tree, and place the tree in a five-gallon bucket of water.  While the tree is still outside, consider spraying the tree with Transfilm, Cloud Cover or Wilt Proof to keep the water loss through the needles to a minimum. If you notice any insects on the tree, blast it with a strong stream of water or consider an insecticidal soap. Let the tree dry before bringing it into the house. 

 

Locate your tree within your house away from heating ducts and the fireplace.  A stand that can hold a lot of water is a big plus because a fresh cut Christmas tree can drink 1-2 gallons of water per day.  Have one responsible adult in charge of watering the Christmas tree daily to avoid ruining the carpet or floors.  If you can, fill (2) one-gallon milk jugs each day and let them sit for 24 hours, this will allow the chlorine to evaporate out of the water.  Letting chlorine evaporate from the water you water your plants is a practice you should use when watering all house plants.  

 

There are many secrets to keeping a tree fresh.  Having a fresh cut and keeping water above this cut always is the most important thing you can do for the tree.  The water conducting vessels quickly close if the tree does not have constant water.  Using a drop of Super Thrive in each gallon of water will help the tree stay fresh. Many people use 7-up and an aspirin in the water. You might want to save the aspirin if you drink Uncle Joe’s egg nogg, bourbon soaked cherries, or Holiday Punch.  

 

Thank you for shopping at Possum’s Landscape and Pest Control Supply and for all your letters, questions, comments when I meet you, and for reading “The Horticulture Hotline”! Make it a Great and Safe Holiday Season!

By Bill Lamson-Scribner

 

I have eight tea olives in my yard that are all over fifteen feet tall. When fall comes and they are blooming and smelling so sweet, I know the hot days of summer are coming to an end. The tea olives are spread in strategic places throughout my yard, so no matter how the wind blows, I will get to smell them. When they bloom, usually the threat of hurricane season comes to an end (fingers crossed), football season is in full swing, the weather is perfect, visits to our local gardens, parks, and plantations are awesome - oysters, anyone?

 

Great weather, cassia blooming, camellias blooming, holly berries, pyracantha berries, nandina berries and fall leaf color – one of the reasons you live in the Lowcountry? The different varieties of Japanese Maples provide many different hues of color in the fall. And of course, there is poison ivy – be sure to garnish your Thanksgiving table with something other than this colorful vine.

 

One big question to answer this time of year is do I want to grow ryegrass in my lawn, paint my lawn green, or let it go dormant? The football fields, soccer fields, baseball fields, and golf courses look so nice this time of year. Green grass all winter would be nice. Many of the people that live in Charleston now are used to green grass in the winter. If you are a little apprehensive, instead of doing the front yard where the whole world can see, try the back yard or a side yard. If you have active children or dogs (the other children), ryegrass can lessen the damage from traffic. Ryegrass does very good under the canopy of oak trees – just ride by The College of Charleston’s Cistern during the winter.

 

While driving through neighborhoods, I see a lot of houses for sale. Ryegrass or green paint could separate your house from the multitude of other houses that are on the market.

For the very low cost of seed and fertilizer or paint, if you could sell your house one month earlier saving you a monthly payment, wouldn’t it be worth it? What about a year earlier?

 

Ryegrass has a bad reputation because people misapply it. I often get asked, “doesn’t rye kill my centipede (or St. Augustine)?” If you manage the rye correctly, you should have no problems. The ryegrass question is like buying a dog. If you base your decision on the few untrained pit-bull stories and never purchased or adopted a dog of any type because of these stories, it would be too bad.

 

The 3 biggest mistakes I see with rye grass that give it a bad reputation are:

  1. Put out at too high of a rate, so it chokes permanent grass.
  2. Use cheap rye with lots of weed seeds and poor color.
  3. No fertilizer programs. Light green grass and no additional fertilizer so dog urine spots (dark green grass) become your fertilizer program.
  4. It is not managed in the spring chemically or culturally, so it competes with permanent grass while it is coming out of dormancy.

 

If you decide you want to put out ryegrass, now is the time to check your trusty application chart. Have you put out a pre-emergent herbicide this fall on your lawn? If so, when and at what rate? If you have recently applied pre-emergent products, you may want to try the paint or wait until next year. You could put out something to deactivate the pre-emergent so you could rye, but that will just add to your cost. If you decide to rye, putting a pre-emergent product in your beds will help to keep rye from popping up in your beds, saving you time and frustration.

 

If you are painting or not using rye, you can attack some of the nasty winter weeds that will compete with your turf grass next spring without having to worry about the rye grass. Painting will also capture heat that will help your grass “green up” sooner in the spring. Who wants to be “mowing weeds” late winter / early spring? Florida Betony and other winter weeds are visible now. Remember it is easier to kill them now when they are young and actively growing than to wait until they are flowering.

 

Three Possum’s Stores hot topic reports – vicious late season mosquitoes, winterizing fertilizers (use SeaHume, Possum’s Minors, 00-00-25, Cotton Burr Compost - stay away from winter fertilizers for fescue and blue grass), large patch (I was trying to avoid saying large patch this week), moles (of course), pots / winter color, fire ants, Neem oil for shrubs, and mole crickets. Bring in your soil test now, so you beat the spring rush!

Wow, we are getting weather that is making it really hard to deal with some of our perennial worst situations this time of year. The rain we had about ten days ago was a perfect slow rainfall that penetrated our landscapes instead of running off into stormwater drains and out into the harbor. Unfortunately, Large Patch loves this moisture too.

 

Rain and nighttime temperatures in the 60’s are perfect weather for Large Patch (Brown Patch) disease in turf. Unless you cover your grass with a tarp, like a baseball diamond, it is hard to turn off the rain. Hopefully, you are managing your irrigation system. It seems like when the skeletons and other Halloween decorations appear in the lawn, so does the Large Patch. With a disease, you want to treat when the conditions are favorable, before you see the damage.

 

All fungus diseases must have three factors line up for there to be an active problem. This is referred to as the disease triangle. There must be a susceptible host (your grass), a favorable environment (in this case cool nights, water, grass is going into dormancy….), and the disease must be present (in the soil in this case). When all these conditions are met, the disease strikes your grass.

 

The quick fix would be to apply Strobe G or T-Methyl throughout the yard. Strobe G and T-Methyl are systemic fungicides that get into the plant (grass) and protect the grass plant from the disease. Getting a flu shot would be a human equivalent. Depending on the weather, rotating chemistries is always a good idea to prevent resistance to the disease. Applying the product before you get the disease when you notice conditions are right, will save you money and time applying the product. You wouldn’t get a flu shot after you had the flu. Unlike the flu shot, Strobe G and T-Methyl do have curative rates.

 

Rats, mice and roaches like to move inside for the winter and the rain just seems to accelerate that migration. The Lowcountry is such a hospitable place, I guess we welcome rats, mice and roaches too! I was looking over some figures the other day preparing for our 2026 season at Possum’s and I was amazed at the amount of products we sell to control these pest. Granted, many of them are sold to professionals; however, they are still used in this area.

 

Do irrigate your yard in the winter because the dry, cold low humidity air can desiccate your lawn, trees and shrubs, similar to the way your lips get chapped. The grass loses water through the runners even though it is dormant and the trees and shrubs lose water through the bark and leaves (if it is an evergreen).

 

Mole crickets and fire ants have been particularly active. With Halloween just around the corner, be sure to manage your fire ants. You would not want that little Princess or Vampire to get bit!
