Keep Weeding, Y'all! 🌱
Pre-emergent Time is Coming Soon: In mid-September it will be time for pre-emergent herbicides to kill winter weeds before they germinate. It's not time yet, but you can go ahead and stock up for September 15th through October 15th when the window is open.
More About Weeds
- Apply post-emergent herbicides directly to existing, visible weeds to kill them once they have already sprouted.
- Right now the best method to combat weeds is to mow them before they go to seed.
- What are pre-emergent and post-emergent herbicides anyway? We explain it in our blog post, What's the Difference?
- Thick Mulch suppresses weeds in flower beds. Spread mulch 2-4" thick and keep it 1-2" away from touching the trunks or stems of your plants.
- Hand Weeding - Dallisgrass is rather large right now; if you haven't tackled it yet, now's a great time as it's cooling off a wee bit and dusk is a nice time for digging.
It's Almost Tall Fescue Time!
- Prepare for overseeding Tall Fescue by cleaning up your lawn and spraying out weeds. This way, you'll have that task taken care of well before planting season and it won't be a last-minute problem to solve.
- Caution: If you plan to plant Tall Fescue seed, don't apply a pre-emergent herbicide in September.
- Systemic protection of the whole plant: Both modes of action are systemic, meaning they work from the inside of the plant to protect the whole plant. What's found at most big box stores is contact only.
- It goes further: One bag will cover multiple applications for the average size lawn.
- Pro-grade: Used by golf courses and we use it in our sod production.
Warm Season Lawns
- Fungicide: Zoysia, Bermuda, and Centipede lawns get an application of Headway G in October (once soil temps lower to 70 degrees) to reduce the possibility of Large Patch. We will remind you next month, just keep it in mind for now.
- Do not fertilize or aerate warm-season lawns in September; wait until spring. Time to let your lawn slowly go dormant over the next several months.
- Apply pre-emergent herbicide in mid-September. For warm season lawns, avoid pre-emergents with nitrogen so you don't push extra growth when it should be going dormant.
Fall Armyworm Alert 🐛
They are on the march now! Learn the signs, scout daily, and act quickly if you see them. Read what to look for in our Fall Armyworm article.
We stock 5-10-30 + Acelepryn insecticide, for preventative control of fall armyworms and grubs. Some of our stores are out of stock, but you can order it for shipment.
Continue to mow warm season lawns at the recommended height until they go dormant in a few months.
It's not time to lower the mowing height on Tall Fescue; that will happen when it cools off.
Mowing Height: There is a healthy range for each type of lawn.

Mowing cuts off flower/seed heads and that stops weeds from making more weeds, thus breaking the life cycle. Mow on a weekly routine and don't let the weeds get ahead of you.
Better yet, a robotic lawn mower will quietly and constantly mow for you and keep the despised weeds from going to seed.
