Tips for Lawn Treatments

So you want to treat your lawn? HERE IS WHAT YOU NEED TO KNOW: 

  • START WITH A CLEAN SLATE. Before applying any treatments to your weed and feed lawn, remove debris, dead grass, or weeds. Think of it like CLEANING THE DIRTY DISHES BEFORE STARTING TO COOK- it’s essential to get the best results!

This allows the treatments to reach the grassroots and work, ensuring a healthy lawn.

  • CHOOSE THE RIGHT PRODUCTS. Every lawn is different. So, choosing the right weed killer and feed products for your specific lawn type is important. 
  • READ THE LABELS to find the right products for your warm-season lawn and to keep those pesky weeds in check! This works for BROADLEAF WEED CONTROL. 

And remember, when in doubt, choose a weed and feed product recommended by an EXPERT for the best results.

  • APPLY AT THE RIGHT TIME. Timing is everything when it comes to lawn treatments. Don’t be a lazy lawn lover! Apply weed killer and feed AT THE RIGHT TIME to make your grass grow nice and strong. 

Trust us; YOUR WEEDS WILL HATE YOU for it! 

Lawn Treatments
  • BE PATIENT. Lawn treatments don’t work overnight, so be patient and give them time to take effect. KEEP WATERING AND MOWING AS NEEDED; your lawn will soon be free of weeds. 
  • If your garden is still full of pesky weeds, maybe it’s time to up your weed-killer game or try a new product! And hey, if all else fails, THROW SOME MONEY AT THE PROBLEM- that usually works. (Just kidding)

How Many Days Should You Wait Before Seeding After Weed & Feed?

Seeding After Weed & Feed


Don’t worry- we feel you.

But WAITING for A LITTLE LONGER to let your weed and feed treatments work their magic is WORTH IT.

Think of it like BAKING A CAKE- you wouldn’t want to add the sprinkles before the cake is fully baked, right?

So, it’s best to wait at least TWO WEEKS before seeding your lawn after applying weed and feed.

But, like with any rule, THERE ARE EXCEPTIONS.

If you’re dealing with STUBBORN WEEDS or the weather is HOT, you may need to WAIT LONGER BEFORE SEEDING.

The key is to KEEP AN EYE ON YOUR LAWN and ensure the weed and feed have had time to kill the weeds before planting new seeds.

Seed planting is like a high-stakes game of musical chairs- PLANT TOO EARLY OR TOO LATE, and YOU’RE OUT! 

But hit that sweet spot, and YOUR GARDEN WILL FLOURISH IN NO TIME. If you find that perfect balance, your plants thrive. 

How to Spread Weed & Feed?

Spread Weed & Feed

Here’s what you need to know:

  • Get the RIGHT EQUIPMENT. So you want green grass and no weeds? It sounds like you need to invest in a top-notch fertilizer spreader, my friend! 

It’s the SECRET WEAPON in the war against weeds and patchy lawns. You also use a handheld spreader for smaller lawns or tricky spots.

  • Follow the INSTRUCTIONS. Hey, don’t chuck weed and feed all over your lawn willy-nilly! Make sure you read the label and apply the RIGHT AMOUNT. 

Otherwise, you might end up with a lawn that looks like it’s been through a weed and feed warzone. 

  • LET’S NOT GO CRAZY WITH THE WEED AND FEED, okay? A little bit goes a long way; pouring too much can hurt your lawn. So TAKE IT EASY, and your grass will thank you! 
  • SPREAD IN A PATTERN. Follow a pattern to apply the feed evenly. Weed and feed application are like painting a wall- you don’t want any streaks or missed spots!

Unless, of course, you’re into the whole patchwork quilt aesthetic. But that’s another can of worms. 

  • WATER YOUR LAWN. Once you’ve applied the weed and feed, turn on your sprinkler system and water your lawn well. 


Weed And Feed Before or After Mowing

How to Mow After Applying a Weed & Feed?

How to Mow

Ready to mow after applying weed and feed?


First, WAIT 24 HOURS after applying the weed and feed before mowing.

This gives the treatments time to soak in and start working their magic.

If you mow too soon, YOU’LL CHOP OFF THE TOPS OF THE WEEDS (a part you’re trying to kill).

When mowing, set your mower to a slightly HIGHER HEIGHT than usual.

This PROTECTS THE DELICATE NEW GROWTH ON YOUR GRASS and gives the weed and feed a chance to do its thing.

And, as always, MOW IN DIFFERENT DIRECTIONS to avoid creating ruts or uneven patches.

In the end, THE KEY IS TO BE PATIENT and give your lawn the time it needs to recover and thrive.

Trust us; your grass will thank you for it (and so will your feet- no more stubbly, prickly grass blades to deal with).

If all else fails, call the professionals and let them handle it (I know I do in my helpless gardener hours).

This is important in the EARLY STAGES OF THE GROWING SEASON when most weed and grass seeds germinate.

Think of it like this- weed control before mowing is like putting up a fence before the cows get out. You’re keeping those PESKY BROADLEAF WEEDS FROM RUINING YOUR PERFECT WARM-SEASON GRASSES.

To use weed and feed before mowing, do what the label says! It’s like following a recipe – read all the instructions carefully, and you’ll be ready to go. 

Make sure to use the liquid weed and feed at the right rate and in the right areas of your lawn.

And remember, treating your ENTIRE LAWN, not just the weeds, is important for the best results.

Once you’ve applied the weed and feed, WAIT AT LEAST 24 HOURS BEFORE MOWING your lawn.

And remember, when mowing weeds, use a SHARP BLADE to ensure a clean cut and prevent the spread of weed seeds.
