1. Keep Up with Summer Mowing (and Reduce the Time Spent on This Chore)

Summer mowing, often a challenging chore due to heat and increased grass growth, typically involves keeping bluegrass and fescue between 2.5–3.5 inches, slightly higher in partial shade. Avoid cutting more than a third of the leaf blade to prevent stress and browning. After extended absences, like a vacation, multiple mowings may be needed, with 3–5 days between each session.

2. Make Sure Your Lawn is Hydrated…But Not Too Hydrated

Despite the temptation to water more in summer, zoysia grasses typically need only 1 inch of water weekly, including rainfall, to avoid disease-promoting waterlogged conditions. Aim for one or two deep waterings early in the morning each week to minimize dew duration and reduce disease risk and take rainfall into consideration.

Watering in the early morning decreases the amount of time dew is present, which is helpful for managing any potential disease outbreaks. Unsure of measuring water? Try an irrigation audit. If heat stress appears, top dressing may help cool and protect your lawn.

3. Be Cautious with Weed Control

Summer is a poor time for weed control use due to potential damage at temperatures above 85°F. It’s better to apply post-emergents when cooler and use pre-emergents in spring and fall to manage seasonal weeds. If temperatures stay below 85°F, applying post-emergent herbicides is safer, but caution is advised due to possible temperature fluctuations.

For more on weed control, see How to Control Weeds During the Summer. Common weeds include white clover, knotweed, spurge, lespedeza, crabgrass, goosegrass, nutsedge and sandspur. Always read the labels carefully before application.

5. Lookout for Bluegrass and Fescue Disease Outbreaks

Monitor your lawn for disease signs like brown patch or powdery mildew and apply fungicides preventatively to maintain health. For lawns with a history of disease, multiple treatments might be necessary, especially in known problem areas. Remember to water immediately after applying granular fungicides to enhance soil absorption.

While chemical treatments are effective, adopting cultural maintenance practices can preemptively deter diseases. These include mowing at the correct height, fertilizing regularly, ensuring the lawn gets one inch of water weekly, applying preventive treatments for weeds insects, and diseases, and maintaining adequate sunlight exposure.

For disease control, we recommend certain products; always read their labels carefully before use.
