August is hot, stubborn, and unforgiving. The best thing you can do this month is protect what’s already thriving, keep water use efficient, and start setting the table for fall improvements.
Watering and irrigation
- Water early in the morning and aim for deep soakings instead of frequent light runs.
- Check your irrigation coverage weekly. August exposes the weak spots: dry corners, clogged nozzles, tilted heads, and overspray onto hardscape.
- Hand-water new trees and shrubs as needed. They often need targeted help even when the lawn looks fine.
Beds, mulch, and weeds
- Keep up with weed removal. Weeds actively compete with plants for water in August’s heat and will quickly colonize bare spots.
- Look for plants that are struggling from heat or drought stress and give them a deep drink rather than a daily sprinkle.
Lawn care
Tall fescue
- Sustain the elevated mowing height. Taller blades improve moisture retention and density, which is critical in August.
- Avoid heavy fertilizing now. Summer feeding can increase stress and disease.
- Start planning for fall renovation. August is the month to get on the schedule for aeration, overseeding, and soil improvement so you’re ready when temperatures break.
Bermuda
- Continue to mow consistently. This practice promotes a thicker, more resilient turf.
- Watch for thin spots from compaction, shade, or coverage issues and make notes for fall corrections.
Trees and shrubs
- Limit pruning during peak heat. If you need to remove damaged limbs or correct a hazard, keep cuts clean and minimal.
- Keep an eye on younger trees for drought stress. Deep watering during dry spells is one of the best long-term investments you can make.
- Check for pest or disease issues and address them early before they spread.
Drainage and storm cleanup
- August storms can be intense and sudden. After a downpour, look for washouts in mulch, erosion on slopes, and pooling near foundations.
- Reset displaced mulch and correct small drainage issues now before fall planting and overseeding season.
Hardscape and outdoor living
- Clean patios, steps, and walkways. Shaded areas can get slick in humid weather.
- If you’re considering a patio, walkway, edging refresh, or drainage correction, late summer is a smart time to schedule so work can happen in early fall.
Outdoor lighting
- A light trim around lights will prevent growth from blocking illumination.
- If you want better visibility at entries, steps, and pathways heading into fall, August is a good month to plan lighting upgrades before days shorten.
