July Tall Fescue Lawn Tips for 2022

Tall Fescue lawns may not be looking their best right now. Hang in there because in two months it will be time to refresh them with overseeding - you and your lawn can make it! Here are tips to help you wait out the summer in best form.

We hope you haven't applied nitrogen fertilizer in several months. Keep holding off until it gets cool again. To help your Tall Fescue do its best over the next two months, we recommend fungicide to prevent brown patch.

Order fungicide online for direct shipment or local pick up. Or let us plan ahead for you . . . sign up for Lawn Coach "Champ" and we'll stick it in the mail at the right time.

💦 How to Water Your Tall Fescue Lawn

Tall Fescue lawns like 2" of water a week during summer. That's up from 1" a week during the cool months.

Water your lawn in the morning: Why the fuss? Water sitting around on leaves promotes diseases. When you water in the morning, moisture rapidly dries from the leaf blades when the sun is out. If you water in the evenings, moisture may not evaporate from the leaves until the next day. Watering in the evenings promotes diseases.


Fertilizing Tips for Tall Fescue Lawns

  • To prevent armyworms and feed your lawn, we recommend our 5-10-30 with Acelepryn insecticide for Tall Fescue. It's safely low in nitrogen and the phosphorus and potassium will benefit overall health. Don't fertilize with high nitrogen until the autumn! Because your Tall Fescue lawn will have slow growth during the warm months ahead, it does not need any nitrogen. Seriously, high nitrogen is a waste of money at this time and it will augment problems such as brown patch.

    👍 Real World Example: Stop using 16-4-8 fertilizers when it's hot. The 16 represents the amount of nitrogen. It's okay to use a low nitrogen fertilizer such as 5-10-30. We know you love to apply products, so want to take another chance to steer you toward applying fungicide instead of any fertilizer through summer.
  • Review the fertilizing schedule in our Tall Fescue Maintenance Guide.
  • Sign up for Lawn Coach and we'll automatically mail you all the right fertilizers when you need them (including the fungicide when you select the Champ package).
  • Even though it's not a good time to fertilize with nitrogen, it's still okay to apply fast-acting lime if you need to neutralize the pH of your soil. Always take a soil test to confirm if you need to apply lime or fertilizer. Balanced soil pH is critical for your grass to be able to use the nutrients supplied by your fertilizer.

Mower Tips for Tall Fescue Lawns

Mowing Height: You should already be mowing at 3-3.5" height for the warm months; we'll remind you in the fall when it's time to lower the height back down to 2.5-3" for the cool months.

Mowing Frequency: During spring you were probably mowing on a once-a-week frequency (we recommend every 5 to 7 days when Tall Fescue is actively growing). During the hot days of summer, your Tall Fescue lawn will slow down, so you'll probably need to mow less frequently. You can keep on a weekly schedule to keep down any weed pressure you may experience, even though you may be mowing off very little of the Tall Fescue leaves.

Getting Rid of Weeds in Tall Fescue Lawns

  • The window for pre-emergent herbicide has closed and we're now in the season of post-emergent herbicide in Tall Fescue lawns: You can apply post-emergent liquid herbicides like Quincept and 3-Way Max for weeds you can see now in established Tall Fescue lawns. Read the label and follow instructions.

    👍 Rule of Thumb:
    It's okay to apply a post-emergent liquid herbicide labeled for Tall Fescue lawns (Quincept and 3-Way Max) after you've mowed a new lawn 3 to 4 times.
  • Pulling by Hand: When you see a few weeds, just pull them up. Sometimes a hand trowel is helpful to get them up by their roots.
  • Mowing: Mow those weeds down before they go to seed. Mowing is an effective way to suppress weeds because it cuts off flower/seed heads and that stops weeds from making more weeds, thus breaking the life cycle. If you have bad weeds, mow on a weekly routine and don't let the weeds get ahead of you.
  • Mulch suppresses weed seeds in flower beds. Spread your favorite mulch 2-4" thick and keep it 1-2" away from touching the trunks or stems of your plants. 
  • Crabgrass is in season! It's crawling all over the place. Read how to get rid of it in your lawn and flower beds: June Weed of the Month: Crabgrass
