What to do this summer
- 1
Mow high
Keep Bermuda Grass at 2–2.5 inches (Bermuda) or 2.5–3 inches (Zoysia/St. Augustine) during Elk Grove’s summer heat. Mow every 5–7 days during peak growth — warm-season grasses grow aggressively in summer. Never remove more than one-third of the blade height in a single pass. Scalping in summer exposes soil to direct sun, increasing soil temperature and moisture loss. Keep your mower blade sharp — dull blades tear grass rather than cutting it, creating brown tips and disease entry points.

Water deeply 2-3x per week
Aim for 1 to 1.5 inches of water per week, including rainfall. Water deeply 2–3 times per week rather than lightly every day — deep watering encourages roots to grow down, improving drought resistance. Always water early in the morning (5–9 AM) in Elk Grove to reduce evaporation loss and lower the risk of fungal disease from overnight moisture. Use a rain gauge or tuna can to measure output. If you see runoff before reaching your target depth, use a cycle-and-soak method — run sprinklers for 10 minutes, wait 30 minutes, then repeat.

Watch for grubs
Check for brown patches that peel up easily like carpet — a classic sign of grub damage in Elk Grove. White grubs (Japanese beetle and June bug larvae) feed on grass roots from May through August. To confirm, pull back a section of brown turf — if you find more than 5–10 C-shaped white grubs per square foot, treatment is needed. Apply a grub-specific product containing chlorantraniliprole (GrubEx) or trichlorfon (Dylox) for active infestations. Preventive applications work best in June before eggs hatch.
- 4
Spot-treat weeds
Hand-pull or spot-spray broadleaf weeds like dandelions, clover, and plantain rather than blanket-applying herbicide across Elk Grove lawns in summer. Broadcast herbicide application during summer heat stresses grass and can cause yellowing or burn. Use a selective broadleaf herbicide (2,4-D or triclopyr) applied directly to weed foliage with a pump sprayer. The best approach is a thick, healthy lawn that outcompetes weeds naturally — plan fall overseeding to fill any thin areas where weeds are taking hold.
- 5
Hold off on fertilizing
Reduce fertilizer frequency during the hottest months in Elk Grove. While warm-season grasses can handle summer feeding, avoid high-nitrogen applications when daytime temperatures exceed 95°F for several consecutive days. If your lawn looks pale, a light application of slow-release fertilizer at half rate is safer than a full dose. Excess nitrogen in extreme heat causes surge growth that the root system cannot support, leading to thatch buildup and increased disease vulnerability.

Signs Your Lawn Needs Attention This Summer
Footprints that stay visible after walking across
Grass blades not springing back is the earliest sign of drought stress. Water deeply within 24 hours.
Blue-grey tint to grass blades
This color shift means your lawn is conserving water. Increase irrigation to 1-1.5 inches per week.
Brown irregular patches expanding outward
Could be grub damage or fungal disease. Pull on the brown grass — if it lifts like carpet, grubs are likely.
Excessive weed pressure in thin areas
Weeds exploit gaps in turf. Spot-treat with selective herbicide and plan fall overseeding to thicken up.
Scalped appearance from cutting too short
Raise mowing height to at least 3 inches in summer. Short grass exposes soil to sun and heat stress.

Frequently Asked Questions
How often should I water my lawn in Elk Grove in summer?
Water your Elk Grove lawn deeply 2 to 3 times per week during summer, aiming for 1 to 1.5 inches of water total. Water early in the morning to reduce evaporation.
Why is my lawn turning brown in summer?
Brown patches in Elk Grove during summer are often caused by heat stress, drought, or grub damage. Check your watering schedule and inspect the soil for grubs.
Should I fertilize in summer in Elk Grove?
Avoid heavy fertilizing during the hottest months in Elk Grove. Fertilizer can burn stressed grass. If needed, use a light organic fertilizer in early summer only.
Should I let my lawn go dormant in summer in Elk Grove?
Cool-season grasses in Elk Grove naturally go semi-dormant when daytime temperatures consistently exceed 85°F. Allowing dormancy is healthier than stress-watering — water deeply once every 2–3 weeks to keep roots alive. Warm-season grasses thrive in summer heat and should NOT go dormant.
How often should I mow in summer in Elk Grove?
In Elk Grove, mow warm-season grasses every 5–7 days during peak growth and cool-season grasses every 10–14 days. Keep blade height at 3–4 inches in summer. Never cut more than one-third of the blade in summer heat — scalping stresses already-hot grass.
