Possum Minors and SeaHume Before Picture
Horticulture Hotline 10/18/26
By Bill Lamson-Scribner
The beautiful fall color has arrived in many parts of the
United States. In the Lowcountry we will get yellow from the Popcorn Tree (a
highly invasive species), the red from Virginia Creeper (nasty vine), more
yellow from the Sweet Gum Tree (the tree with the medieval, spiked balls), and
don’t forget the red from Poison Ivy. This year we seem to get a bonus red in
mounds – the red imported fire ant mounds! The yellow flowers from Cassia and
the red flowers from bottle brush always make a great fall color show! Japanese
maples and their many varieties provide great fall color. The fragrant tea
olive will add its wonderful scent.
Yes, it is time to winterize your landscape. SeaHume should
be used alone or with the 00-00-25, depending on the results from your soil
test. Look for a product with a 00 for the first number (nitrogen). A 00-00-25
with sulfate of potash and minors would be great. If you do not need the
potash, consider just SeaHume, a wonderful combination of seaweed and humic
acid. If you would like your yard to stay green later in the fall, try Possum
Minors along with SeaHume (this combination is illustrated in before and after
pictures).
Possum Minors as its name implies is full of iron and other
minor nutrients that promote ‘green ‘without top ‘growth’. By having your plants,
including grass plants, green at this time of year the leaves can capture more
sun and produce more carbohydrates to grow roots. Since the mowing has slowed
down, you will be able to enjoy the ‘green’ for a longer period, since the
‘green’ won’t be getting mowed off.
SeaHume will help grass, trees, shrubs, and flowers
throughout the winter. SeaHume will help mitigate salt damage. The seaweed part
of SeaHume has over 60 minor nutrients, carbohydrates, amino acids,
gibberellins, auxins, cytokinin’s, antioxidants and other bio stimulants. The
humic acid is also full of bio stimulants that help make nutrients that are in
the soil available to the plant, help with soil structure, grow roots, and feed
the microorganisms in the soil.
Trees grow most of their feeder roots over the winter. SeaHume
will help grow these feeder roots over the winter preparing the tree for
whatever the spring weather brings. Drought like this year?
Beware of the national ad campaigns talking about
winterizing fertilizers for turf. These products are usually formulated for
cool season grasses (rye, fescue). I saw one over the weekend that was a 32-00-10.
Not exactly what we want to put on our yard in late-October in the Lowcountry.
Just ask Clemson University.
Have you ever had winter kill? Now is the time to prepare
your grass for the wide variations in temperatures we have. If you had winter
kill in the past, you need to be sure to correct low and poorly drained areas,
reduce thatch in the yard, increase air movement in low areas, keep your lawn
hydrated and feed (with the right food for the winter).
Mow your grass lower than normal (centipede 1.0 to 1.5
inches, St. Augustine 2.5 to 3.0 inches). By mowing your grass lower, you will
increase the air movement around the crown of the plant, so cold air will not
settle at the crown of the plant and damage the grass. In Florida helicopters
fly low over citrus groves that are in valleys to get the cold air out. Tall
grass or thatch will insulate the crown of the plant like a goose down jacket,
keeping the cold air near the crown where it can cause winter kill. Centipede
lawns usually get winter kill the worst if temperatures plummet quickly.
Fine blade Zoysia grass can grow very dense and get thatch.
De-thatching, aerating and verticutting are great cultural practices while the
grass is actively growing. This time of year, using Bio Grounds Keeper, SeaHume
and very light topdressing of Cotton Burr Compost should be part of your
maintenance schedule.
Moles? Armyworms? Winter flowers for pots? Mosquitoes? Mole
Crickets? Mice? Rats? Roaches?
