Dry Again!

 

Horticulture Hotline 04/13/26

 By Bill Lamson-Scribner

 

Another dry Spring. Do you have mites trying to come into your house for some water? I did a little shopping on the broken bag pallet at Possum’s and have been putting out organics to bring my grass out of dormancy – Perk, SeaHume, Organic Dethatcher, 04-04-04, and dolomitic lime (based on soil test). I also used a broken bag of fungicide, insecticide, and pre-emergent. The one thing that probably saves me the most time is something I put on my shrubs called Cutless Growth Regulator – no pruning or picking up after pruning!

 

While working in the stores, a common concern I hear is that “I missed the time to preemerge”. Different weeds germinate at different soil temperatures if adequate moisture is available. Crabgrass is an early germinating weed. Later comes goosegrass. Then the dreaded Doveweed germinates. Not all the crabgrass seeds germinate at one time either. Keeping a protective barrier up according to the label is the most important strategy, and you can begin that any time of year.

 

The biggest issue I see is the lack of rain. The high blue skies with the lower humidity and the high winds will dry out an area very quickly. Water, water, water and use a wetting agent to get the most out of the water when you water or when it rains.

 

Possum’s Wetting Agent with Biostimulants (PWAB) is a product that helps water move deeper into the soil. PWAB will help soften clay for water penetration and get rid of those localized dry spots in your lawn. Sandy soil will hold water longer and prevent those localized dry spots. Wetting agents have shown to reduce watering needs from 33% to 66% in Arizona and other areas where water is limited. If you could go from watering three times a week down to once a week or not at all, think of the savings!

 

 The benefits of using a wetting agent would be far greater than just the savings with the water company. Since the water would penetrate deeper into the soil, the root systems of your grass and plants would grow deeper. As the roots of your grass and plants slough off and are replaced by new roots, organic material is increasing in the area where these roots are shed, creating a deeper top-soil area.

 

 A deeper root system will help in times of drought and can collect more nutrients from the soil. If you use fertilizer, a deeper root system can absorb more nutrients before they leach away; therefore, you can use lower fertilizer rates. If you use root absorbed systemic fungicides or insecticides, a deeper root system will also “catch” these products more efficiently giving you more “bang for your buck”.

 

When it rains, a yard treated with a wetting agent like Possum’s Wetting Agent with Biostimulants has less runoff. The rain penetrates the ground much easier, keeping the rain in your yard and not in the storm water drains. If you have ever poured water out on a dusty dirt road, and watched the water bead up and not penetrate the road, you have witnessed a hydrophobic soil condition. If you add a little wetting agent to this water and pour it on the same road, the water would penetrate the dusty dirt road. By keeping the water in your lawn, you will have the benefit of the water, and we will have less runoff into our marshes.

 

The biggest savings from using a wetting agent will come from reduced use of fungicides. Most fungi like water. By watering less fungus populations should decrease.

Brown patch / large patch and gray leaf spot comes to mind.

 

Many people that live in the Lowcountry travel. PWAB is great to add to hanging baskets or pots. Whether you are travelling or just want to increase your intervals between watering, PWAB should help you with a more uniform distribution of water and better hydrated plants.

 

If you prefer a granular product over a spray, try HumGranWet. HumGranWet is very cost-effective product that combines a wetting agent and humic acid. If you would rather spread than spray, check it out. HumGranWet has a very low use rate (1.15 pounds per thousand square feet 4 times a year or 2.3 pounds per thousand square feet every 6 months) and long residual making it very affordable!

 

People come into Possum’s and say that the savings on their water bill more than pays for the Possum’s Wetting Agent with Biostimulants. All the other benefits are an extra (free) bonus!

The pollen and the gnats are here and so is Spring! Spring is like St. Patrick’s Day when everyone is Irish for the day. It seems like everyone is a gardener in the Spring.

 

Liriope (monkey grass), holly fern, and cast-iron plant will benefit from cutting back to remove old, discolored foliage this time of year. Some people use a lawn mower, others hedge shears.  I do not know why, but I can convince people to cut back their Liriope; however, trying to get them to cut back holly fern and cast-iron plant is not as easy. I see more people pruning individual leaves than just cutting the whole plant back to the crown. The completely new growth from the cast iron plant and the holly fern will look as spectacular as the new growth from the Liriope. Get rid of all that tattered old foliage! 

 

It is very important to manage your winter weeds now. Burweed (low to the ground with a sticker in April to May – it’s seed), henbit, chickweed, and the dreaded Poa (annual blue grass) are a few of the more prevalent, troublesome winter weeds. Although winter weeds will die when the temperatures warm, they will be producing thousands of seeds for next year’s crop until they die. These seeds add seeds to the “seed bank”. A manufacturer of preemergent products once told me that they like a minimum of 85% of control of weeds with their product before turning it over to the EPA for testing and labeling. If your seed bank is 100, you would have 15 weeds. If your seed bank is 100,000, you would have 15,000 weeds! The seed bank is a good bank to have overdrawn.

 

Control small seeded annual summer weeds now with a pre-emergent product. We (Possum people) talk about target dates to put out pre-emergent products in the lawn and beds; however, different weeds germinate at different soil temperatures provided they have adequate moisture. Weed seeds germinate throughout the year here, so be sure to have out your protection. Always follow the label of the product you are using so you do not overdo it and be sure you are waiting for the proper intervals between applications.

 

If mulching, 2 – 3 inches is the latest recommendation. Keep the mulch off the trunk of the tree. Cotton Burr Compost as a mulch can add a lot of nutrition and a sip of compost tea (and lord knows we love our tea) every time it is irrigated.

 

Soil Test? Bring them to Possum’s for accurate testing and an easy-to-follow interpretation of the results.

 

After you have done some ‘Spring Cleaning’, SeaHume and Cotton Burr Compost with their loaded micronutrients and biostimulants should help your plants and turf come out of dormancy healthy.

 

If you have plants like Viburnum (white flies), Camellias (scale), Gardenias (white flies), Crepe Myrtles (bark scale, aphids), Lantana (lace bugs), or any other plant that you know regularly turns black from sooty mold, consider drenching with Dominion Tree and Shrub for season long control of sucking insects. This systemic product is awesome!

 

Two more things since I am running out of column inches. Large patch fungus is active again now that the soil temperatures have warmed. If you have a history of the disease, use a control product preventatively. If you have an irrigation system, go through it and make sure everything is working.

 

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

While in Possum’s the other day, I was amazed we were already getting hit with the question, “who is a good lawn care company?”

 

I have been hit with some variation of this question a lot recently in different situations. Since we sell products to many different companies, it is best to ask your friends. We rarely see the end results of our customers’ applications to various yards. Also, we wouldn’t want you to be at a family reunion talking to your distant cousin that is also a good customer of ours and say that Possum’s recommended a different company other than your distant cousin.

 

Lawn care companies can spray several different products to solve several different issues at once. To tank mix different control products, they need to make sure the products are compatible with each other.  Also, the lawn care applicator must calibrate the sprayer to make sure they are getting the proper amount of product out, in the given amount of square feet according to the product labels.  Knowing the correct amounts to put into the sprayer to control what you are trying to control is critical.  Does this all sound “Greek” to you?

 

A professional lawn service is licensed by the state to apply control products, and they have to take continuing education courses to maintain their license. Most companies have different programs, and they will either treat your yard on an “on call” basis, quarterly program, or complete yearly programs.  Check with the individual companies for what they have to offer. Just beware that if your yard is all green weeds and they kill all your weeds, then your yard will be brown. I have been told, “Bill, they came out and killed my yard!” When the yard was weeds and they killed the weeds.

 

When choosing a lawn care company or any contractor, it is good to get references from neighbors and friends.  With lawn care companies, it is especially important to find one that is doing good work in your neighborhood.  Most applicators that work for a lawn care company have a route in a certain area and different applicators have different abilities and experience.  If you sign up with a company who is doing a good job at your neighbor’s two doors down, chances are you will get the same applicator that they have. Whereas if your friend from across town recommends a company, you might be assigned an applicator with more experience or less experience – a little bit of a gamble.

 

One thing to remember, even though your house is right next to another house, the results of lawn care can be totally different because of sun / shade patterns. Trees and the way your house is positioned on your lot can greatly affect the way the grass grows. A sunny yard is best for good grass growth. The type of grass and soil could vary as well.

 

If you would rather, do it yourself, get on a custom program based on your soil from Possum’s. I know that I can buy paint, but I would rather the professionals handle that job!

New growth is beginning on trees, shrubs, and grass throughout the Lowcountry. Are you ready? Soil test with custom program? Removed leaves from the lawn areas? Has your lawn mower been serviced (better hurry)? Applied preemergent weed preventer to lawn and bed areas? Killed winter weeds that are competing with your existing grass and getting ready to produce many more seeds for you to fight next year? Controlled your moles? Pruned what needs to be pruned? Clean out your beds for sanitation purposes, especially the beds where plants that normally have leaf spot diseases are located? Applied SeaHume and other organics, so the landscape above and below ground (microorganisms, roots) have food to feed the new growth? If you have citrus, have you hung up your Citrus Leafminer pheromone traps to protect the new growth?

 

If you have been plagued by black sooty mold in the past, right now, apply Dominion Tree & Shrub as a drench to these plants to control the insects that produce the black sooty mold. Get it out now to protect the new foliage from insect attack. Insects like that young tender foliage like us (cabbage, spinach, lettuce). Neem oil and horticulture oil are also a way to get ahead of the insects. Viburnum, crepe myrtles, and sweetgrass are a few of the plants we hear the most about at Possum’s.

 

Now, it is a great time to inspect your trees for torn limbs that need to be properly pruned. Many of my deciduous trees (trees that lose their leaves) are either just starting to put on new leaves or still naked. Have you inspected your yard for mosquito breeding areas? Do you have liriope that needs to be cut or mowed. Cast-Iron plants? Have you seen any Lady Banks Roses, Saucer (tulip) Magnolia (my favorite small tree) or Carolina Jasmine blooming? How about the smell of sweet tea olive?

 

For all you sweetgum tree ‘haters’ out there because of their mace (not to be confused with the politician) like gumballs, this is the time you can do something about it. If you look up at your sweetgum tree right now, you should see little off-white cream-colored flowers that are going to become this year’s crop of gumballs. 

 

There is a product called Snipper that will destroy the flower, preventing the development of the gumball. This is not a one-time application, so plan to do it anytime you do not want to have gumballs. The timing is very important, so if you miss the flowers this year, begin to make your plans for next year. Since the application involves drilling holes in the sweetgum tree, a licensed and insured tree care professional is always a good idea. Getting on their schedule in the fall, so they can measure the tree’s diameter, give you an estimate and order in the product, so they will be ready when the timing is right and will help with the success of the application.

 

Last fall there was a crazy amount of large patch fungus. Are you ready to prevent the disease from attacking your grass? When the grass is coming out of dormancy, it is very susceptible to the disease. Look in the same areas that you had it last fall for the disease.

 

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

Daytona 500, SEWE, Valentine’s Day, and the soil temperatures are all lining up to indicate it is time for preemergent products to be applied to your lawn and beds. Get out your preemergent or forever fight weeds!! Remember to treat you turf and beds, so you do not have to waste time battling the weeds.

 

Different weeds germinate at different soil temperatures. Crabgrass is the first summer annual weed that we are targeting for control. Goosegrass comes later and the ever-hated Doveweed germinates last out of these three. In the Lowcountry our soil is warmer than other parts of the country, so microorganisms in the soil that breakdown the preemergent barrier are more active than in cooler climates. Therefore, it is good to use split applications of preemergent products. Always read, understand, and follow product labels.

 

For the last time, well maybe not, kill those winter weeds now before they seed and add to your ‘seed bank’ (and the Lowcountry’s) for next year! Now is the time! Warmer temperatures and we should get some rain for some soil moisture will aid in the killing of a weed. An actively growing weed is easier to kill than a drought stressed weed.

 

Trees grow. Some experts say it is around 18 to 24 inches at the tips of the branches all around the circumference of a healthy tree. Areas of grass might be shaded and thin that were once high-quality turf. Now, it might be a good time to cut new bed lines and let the tree have more room to grow. Check the sides of your house for limbs rubbing the paint off your house. The paint protects your house like your skin protects you or like bark protects a tree.

 

Look above your roof line and see if any limbs are growing above your roof that could allow varmints (squirrels, raccoons, or the loveable possum) into your attic. Make sure your source of power to your house is free of limbs. Hire an insured arborist if you need some pruning done. Before a tree puts on new leaves, it is a great time for an arborist to inspect the health of your trees. An arborist can see cavities, crossing limbs, and other situations easier if the tree does not have leaves (not evergreen).

 

If an arborist needs to do some pruning, it is good to do that before the tree uses the energy to put out new foliage that is going to quickly be removed. Of course, here an arborist can prune any time of year. It is also a good time to fertilize trees with the right fertilizer, so that they have the nutrients to put on new growth for the new season and a strong root system.

 

Any transplanting or planting of new trees or shrubs should be done as soon as you can. Try to get them in the ground before the plant flushes out new growth or blooms. If you are buying a blooming plant that you want a specific color or to match a color you already have, you may have to wait to see that the bloom on the plant (do not always trust the tags) is the color you want; otherwise, the sooner you can plant the better.

 

When planting remember the Diehard Transplant or GroTabs, it is like yogurt (full of probiotics). Diehard Transplant adds all the good bacteria, wetting agents, and fungi into the soil that a plant needs to help with survival. Remember the old saying when planting, “plant it high and it will not die!”

 

Intice 10 perimeter bait is a great product to put out around the perimeter of your house for roaches, crickets, sowbugs, earwigs, silverfish, millipedes, and certain ants. Intice 10 is a LEED tier 3 product and N.O.P. (National Organics Program) compliant, so it is considered very safe.

 

Intice 10 should also be broadcasted in the yard for mole crickets. Mole crickets come to the surface on these warm days and love to eat this bait!

 

My bald cypress has begun to “needle out” and my fig tree has new buds emerging. Time to go on an organic binge with SeaHume, Cotton Burr Compost, Vermaplex, worm castings, Nature’s Blend and others! Of course, anytime is a great time for organics.

 

If you have a history with fungus or insects on certain plants, sanitation, lime / sulfur, and your fungicide or insecticide of choice is good to put out now to protect the new growth. With the amount of large patch fungus we had this fall, apply products preventatively as the conditions get right, so you can use lower rates.

 

Other things – make sure mower is good to go – air filter is key, check irrigation, treat for fleas (growth regulator is key) and ticks, take soil test, prune roses, work on breeding sights for mosquitoes, kill winter weeds before they make seeds for next year (I could not resist), spray neem oil or horticultural oils for overwintering insects, apply Dominion Drench to perennial insect loving plants…

 

Spring in the Lowcountry… Work hard, then head to an oyster roast!

The Saucer or Tulip Magnolias are blooming, which usually indicates spring is rapidly approaching. Camellias are blooming. My Bottlebrush has survived so far. Hibiscus, lantana, and cassia are not so lucky. The trees are swelling with water as evident by the lichens on the ground. The red maple trees are providing their new growth red color.

 

The time is now to introduce some organics to your landscape. SeaHume, with its high humic acid, seaweed, and carbon content, is a great choice. SeaHume is very concentrated organic material that has been compacted under heat and pressure over time and is mined. Cotton Burr Compost also does a terrific job this time of year. The two products together form a serious synergy in the soil. Food for microbes and a five-star hotel!

 

The soil temperature indicates that it is just about time to apply preemergent products to your beds and turf. Valentine’s Day (rose grower’s do you have your pruners and organics ready?), Southeastern Wildlife Expo, and the running of the Daytona 500 are just around the corner. The time to apply the magical weed preventer is coming up fast.

 

Depending on which Phd doctor you believe, crabgrass germinates when the soil temperature (3 inches deep) stays above 55 degrees (some doctors say 57 degrees), for 3 straight days provided adequate moisture in the soil. Now some doctors say remains 57 degrees or above for 24 hours at a depth of 3 inches with adequate moisture.  The manufacturers of the preemergent products suggest that you apply the product 2 weeks before the temperatures are right, so you must be able to predict the future. Do you have a crystal ball? If you are not into monitoring the soil temperature and do not have ESP (do people, still use the term ESP), Valentine’s Day or the running of the Daytona 500 should work for you.  Spreading a preemergent product now could save hours of spot spraying later.

 

The turf areas as well as the landscape bed areas will greatly benefit from the use of preemerge products. Not only will the yard look better, but your plants will not have to compete with the weeds for sun, nutrients, and water. If you are controlling weeds with pre-emergent products, there are less weeds there for you to spray or pull, saving you time. There is also less stress on you trying to find time to control the weeds in your yard later once the weeds have emerged. Control them now with a preemergent control product!

 

For those new readers of the Horticulture Hotline, preemergent control products kill weeds as they germinate.  The weeds never come up and you never have to worry about them.  Crabgrass, goosegrass, barnyardgrass, crowfootgrass, dallisgrass (seedling), foxtail, annual bluegrass, smutgrass, barley, kikuyugrass, wild oats, bittercress, carpetweed, chickweed, Carolina geranium, henbit, knotweed, lespedeza, marestail, black medic, mustard, oxalis, pineappleweed, pigweed, redroot, parsley-piert, purslane, rocket, shephardspurse, speedwell, spurge, and woodsorrel are examples of weeds controlled by preemergent products.  Small seeded annual weeds are controlled by preemergent products.

 

Read the label of the specific product that you are using to get an exact list of weeds that the manufacturer has tested and shown to control. Preemergent products applied now do not control winter annual weeds that are already up like annual blue grass. To control annual bluegrass, you would have used a preemergent in August and again in October (this could vary with products and rates – follow the label).

 

Clover, Florida Betony, Nutsedge and Dollar weed are not controlled by preemergent control products.  These are perennial weeds. Weed Free Zone is a liquid that will do a good job on controlling many of your broadleaf weeds. The Nutsedge will require a different product and is most likely not visible right now.  It is important to control these weeds that you see now (henbit, chickweed, annual bluegrass) before they go into their reproductive stage (flowering).  A weed in its reproductive stage is harder to control than a weed in its vegetative stage. By controlling the weed now, you avoid having to deal with more weed seeds next year.

 

It is very noticeable when you ride through the Lowcountry which homeowners and which businesses used preemergent products last fall at the correct time. One business or home lawn will be nice and brown and dormant without a spec of green in sight. Right next to it will be brown turf mixed with green weeds. Again, it is very important to control those weeds that are up now before they begin to flower.

 

If you missed your fall application of preemergent, use a post-emerge product along with your preemergent product. Kill what weeds are up and control summer annuals weeds before they come up! Great way to be a lawn hero by killing the weeds and not have to mow for the next two and a half months when you are basically mowing weeds. Killing weeds before they seed reduces your weed population greatly. One annual bluegrass plant produces about 6000 seeds! Some people will say do not worry about controlling winter weeds now because the heat will kill them in May. Do you want to add all the weed seeds to your yard in the meantime and have your grass coming out of dormancy compete with the weeds?

 

If you are trying to control weeds in the lawn that are up and starting to flower or seed, mow – wait 2 days and spray – then wait at least another 3 days before you mow again. The mowing will get the weeds actively growing and weeds that are actively growing are easier to kill. If the product is root absorbed, be careful around desirable plants, and water them properly. If you water in too much, you could move the product past the shallow root zone of the weed you are targeting.

 

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

Snow Gone - Weed Control Time!

Weed Free Zone

Horticulture Hotline 02/02/2026

By Bill Lamson-Scribner

 

The perfect snow in the Lowcountry! Here one day and gone the next!

After a snow event, the winter weeds really stand out in the grass and should be managed before the go into the reproductive stage of their life cycle when they are harder to kill and they are producing more plants for you to manage the following year.

 

Weed Free Zone (liquid), Vexis (granular) and Dollar Weed Control (granular) are three great products for now. Atrazine (granular or liquid) containing products also are available. These products control weeds in lawn areas. Read the label closely before you decide on a product because they are all different and have certain cautions that you would want to be aware of before using.

 

Weed Free Zone is a liquid workhorse, controlling many weeds. Aster (White Heath And White Prairie), Bedstraw, Beggarweed (Creeping), Bindweed, Black Medic, Broadleaf Plantain, Buckhorn Plantain, Bull Thistle, Burclover, Burdock, Common Buttercup, Creeping Carpetweed, Chickweed, Common Chicory, Cinquefoil, Clover, Compassplant, Curly Dock, Dandelion, Dayflower, Deadnettle Dock Dogfennel English Daisy False Dandelion (*Spotted Catsear And Common Catsear) Field Bindweed (*Morningglory And Creeping Jenny) Field Oxeye-daisy (*Creeping Oxeye) Filaree, Whitestem And Redstem Florida Betony Florida Pusley Ground Ivy (*Creeping Charlie) Groundsel Hawkweed Healall Henbit Innocence (Blue-eyed Mary) Lambsquarters Lawn Burweed Lespedeza, Common Mallow, Common Matchweed Mouseear Chickweed Old World Diamond Flower Oxalis (*Yellow Woodsorrel And Creeping Woodsorrel) Parsley-piert Pennsylvania Smartweed Pennywort (*Dollarweed) Pepperweed Pigweed Pineappleweed Plantain Poison Ivy Poison Oak Prostrate Knotweed (*Knotweed) Puncturevine Purple Cudweed Purslane Ragweed Redweed Red Sorrel (*Sheep Sorrel) Shepherdspurse Spotted Spurge Spurge Thistle Veronica (*Corn Speedwell) Virginia Buttonweed White Clover (*Dutch Clover, Honeysuckle Clover, White Trefoil And Purplewort) Wild Carrot Wild Garlic Wild Geranium Wild Lettuce Wild Mustard Wild Onion Wild Strawberry Wild Violet Yarrow Yellow Rocket. Read the label before applying!

 

Dollar Weed Control should not be used on dormant centipede grass; however, if you do not have centipede, it is labelled to kill some hard to control weeds - Controls: Chickweed, Clover (Hop, Red & White), Dandelion, Dollar Weed, English Lawn Daisy, False Dandelion, Florida Betony, Ground Ivy, Lespedeza, Black Medic, Parsley-Piert, Broad leaf Plantain, Buckhorn Plantain, and Virginia Buttonweed. This centipede grass restriction illustrates why you should always read and follow product labels.

 

Vexis is a great newer product that controls hard to kill weeds and nutsedges. Vexis has an interesting (to me – maybe not to many others) statement on it’s label. To avoid injury to improved varieties of St. Augustinegrass or Centipedegrass, apply when night-time temperatures are above 50°F for 7 consecutive nights. As you can see, Vexis controls some tuff weeds. Sedges, Kyllinga, and Rushes (including ALS resistant annual sedges): Yellow Nutsedge, Purple Nutsedge, Annual Nutsedge, Green Kyllinga, False Green Kyllinga, Cockscomb Kyllinga, Annual Kyllinga, Path Rush.

Nice not to have to water in product before reentry to area. Great product! As always, read and follow the product label.

 

Get ahead of small-seeded summer annual weeds with a preemergent herbicide in about two weeks.

 

With “spreader season” beginning make sure your spreader is ready for action before you put product in the hopper because spreaders are known to rust over the winter.

 

The cold weather has forced many rodents to seek refuge under and inside many homes in the Lowcountry. To avoid smelling the dead varmint, snap traps and glue boards are the way to go. Baits are very effective; however, you might have to smell a dead animal for a few days if they die in a crawl space or wall void.
