10 Yard Tasks to Tackle in August Before Fall Catches You Off Guard

August in Northeast Ohio brings warm days, cooler nights, and that sneaky feeling summer’s about to slip away. It’s easy to get distracted by back-to-school chaos or late vacations — but your yard still needs attention. In fact, August is the perfect time to get ahead of fall maintenance.

From lawn care tweaks to planting prep, these 10 August yard tasks will set you up for a smoother transition into autumn and give your property a polished, well-cared-for look.

1. Edge and Refresh Your Mulch Beds

Your spring mulch has likely faded, thinned out, or been kicked around by storms and summer foot traffic. August is a great time to:

• Top off mulch in thin spots (no more than 2–3 inches total)

• Redefine bed edges with a spade or edging tool

• Pull late-summer weeds before they set seed

A crisp edge and fresh layer of mulch instantly improve your yard’s appearance — and it’ll make fall leaf cleanup easier when beds are clearly defined.

2. Deadhead Perennials and Cut Back Spent Growth

August is your last chance to clean up perennials before they begin preparing for dormancy. Focus on:

• Deadheading flowers like coneflowers, black-eyed Susans, and daylilies to encourage one last bloom

• Cutting back leggy or yellowing stems

• Removing any diseased foliage to prevent spread

This cleanup reduces stress on your plants and helps them store energy for winter.

3. Overseed and Repair Your Lawn

If your grass took a beating during summer heat, early August is the ideal time to patch thin areas or overseed bare spots.

• Use cool-season grass seed like fescue or Kentucky bluegrass

• Rake and loosen soil, apply seed, and gently water daily

• Consider core aeration beforehand to improve seed-to-soil contact

By seeding now, you’ll get strong root growth before the first frost — and a much greener lawn next spring.

4. Trim Shrubs and Bushes for Structure

Skip major pruning, but do take time to clean up fast growers like forsythia, spirea, or privet that have put on wild summer growth.

• Focus on shaping rather than hard cuts

• Remove any branches touching the ground, siding, or windows

• Watch for suckers and remove them from the base

A light trim now keeps plants healthy and tidy as they prepare for fall dormancy.

5. Start Your Fall Veggie Garden

Believe it or not, August is prime time to plant fall crops in Northeast Ohio. Focus on fast-maturing or cold-hardy vegetables:

• Lettuce, spinach, kale

• Radishes, turnips, beets

• Broccoli or cabbage seedlings

Clear out spent summer crops, amend soil with compost, and water consistently — especially during hot spells.

6. Clear Out Problem Weeds (Before They Go to Seed)

If you’ve been letting that patch of crabgrass or thistle slide, August is your last window to stop them from spreading.

• Pull by hand or spot-spray invasives before seed heads develop

• Consider laying cardboard and mulch for persistent areas

• Use this time to identify and remove creeping vines, like bindweed

Letting weeds seed now means a much bigger headache in spring.

---

7. Inspect Drainage and Gutter Areas

August is often dry, but fall rain is around the corner. Check that:

• Downspouts and splash blocks are aimed away from the house

• Low spots in the yard aren’t collecting water

• Gutter outlets are free of plants or debris

Fixing minor grading or adding extensions now avoids basement issues and erosion later.

---

8. Divide and Transplant Overgrown Perennials

Plants like hostas, daylilies, and irises can be dug up and divided now so they’re ready for root establishment before cold weather.

• Choose a cloudy, cool day

• Water deeply the day before digging

• Trim excess foliage to reduce transplant stress

You’ll get more plants for free and reduce overcrowding in existing beds.

---

9. Prep Tools and Equipment for Fall Use

Before you stash the mower for the season or dig out your leaf blower, do a quick tool check:

• Sharpen blades, especially pruners and loppers

• Clean and oil hand tools

• Check spark plugs and fuel lines on gas equipment

Being proactive now means no delays during peak fall cleanup.

---

10. Plan Hardscape or Planting Projects Before the Rush

If you’re thinking about installing a patio, firepit, or raised beds, August is your moment.

• Soil is still workable

• Plants are readily available (often at discount)

• You’ll beat the fall contractor rush

Even small upgrades, like adding stepping stones or container plantings, help boost curb appeal before real estate season picks up again.

🌿 Bonus Tip: Take Photos of Trouble Spots

While you’re out doing yard work, snap photos of areas that consistently struggle — like soggy corners, bare patches, or failing plants. Use these images to:

• Ask for expert advice this winter

• Track changes over time

• Plan upgrades during the off-season

Documentation now helps you make smarter decisions later — especially if you plan to hire help or DIY solutions next spring.

FAQs

When should I stop watering my lawn in Northeast Ohio?
You can taper off watering once temperatures cool consistently in late September, but August is still hot — aim for 1–1.5 inches per week of water, ideally in early morning.

Can I still plant new trees or shrubs in August?
Yes! August is a good time to plant, as long as you water deeply and consistently. The warm soil helps roots establish quickly before fall.

Is it too late to mulch in August?
Not at all. Mulching in August helps retain soil moisture during dry spells and reduces weed seed spread — just don’t overdo the thickness.

What should I do with my summer annuals?
If they still look good, let them ride into September. If they’re leggy or done, remove and compost them to prep beds for fall planting.

Should I fertilize in August?
For lawns, hold off until September for fall fertilizer. For flowers and veggies, a mild organic boost like compost tea or fish emulsion can help during late-summer growth.
