What to Spray Now: Late Season Weed & Pest Control Timing Guide

Because “I’ll get to it next year” is the reason your lawn looks like a jungle in June.

Fall might feel like a time to wind down your yard work, but trust us — there’s still plenty of action happening beneath the surface. And if you time your final treatments right, you can set your lawn, landscape, and sanity up for a much smoother spring.

Here’s your no-fluff, late-season cheat sheet on what to spray right now to finish strong and stop pests and weeds from making a comeback next year.

Tree & Shrub Root Feeding

(Yes, again. Because it’s that important.)
Fall is prime time for root development — and a well-fed tree is a healthy tree come spring.

If you missed your earlier chance, there’s still time… but not much.

Timing Matters — Don’t Wait Too Long

Many of these treatments lose effectiveness once soil temps drop too low or the first freeze hits. Aim to apply:

Bonus Tip: Don’t Waste Product

Trying to spray a dormant weed or treating frozen soil is like putting on sunscreen at night — technically possible, but completely useless.
