Seasonal Landscape Care
Heat & Drought Care
Minnesota summers can push a landscape to its limits. Long stretches of heat and drought stress lawns, trees, and beds in ways that aren’t always obvious until damage is done. This guide walks you through recognizing stress early, watering the right way, protecting your soil, and helping everything recover once the rain returns.
Recognizing Heat & Drought Stress
Stress shows up differently across your landscape. Catching it early gives you time to adjust watering before minor wilt turns into permanent loss.
Lawns
Grass turns a dull blue-gray before it browns. Footprints that stay pressed into the lawn instead of springing back are an early warning sign of drought stress.
Trees & Shrubs
Look for wilting leaves, scorched brown edges, and early leaf drop. Newly planted trees and shrubs are especially vulnerable during their first two summers.
Perennials
Drooping midday that doesn’t recover by evening signals real trouble. Faded flower color and crisp leaf tips mean the plant is rationing what little moisture it has.
Mulch Beds
Thin, dried-out mulch that has faded to gray no longer holds moisture. If the soil beneath the mulch is dusty and cracked, your beds have lost their protective buffer.
Watering Strategies During Heat
Deep, infrequent watering builds resilient roots. Frequent shallow sprinkling does the opposite, training roots to stay near the surface where they dry out fast. Water in the early morning to minimize evaporation and fungal disease.
Lawns
Aim for about one inch of water per week, delivered in one or two deep soakings rather than daily sprinkles. Water between 4 and 9 a.m. so the blades dry before evening. A tuna can set on the lawn is a simple way to measure how much you’ve applied.
Trees & Shrubs
Water slowly and deeply at the drip line, letting moisture soak 12 to 18 inches down. A slow trickle from a hose over an hour beats a quick blast. Established trees need less frequent attention, but young plantings benefit from a deep drink once or twice a week.
How Mulch Protects During Drought
Mulch is one of the simplest and most effective tools for surviving a dry spell. A well-maintained layer keeps roots cool and holds moisture in the soil far longer than bare ground.
Benefits
Mulch slows evaporation, insulates roots against extreme heat, and suppresses thirsty weeds that would otherwise compete for water. As it breaks down it also enriches the soil, improving its ability to hold moisture over time.
Best Practices
Maintain a 2 to 3 inch depth for the best balance of protection and airflow. Always keep mulch a few inches away from tree trunks and plant stems, since piled-up mulch traps moisture against bark and invites rot and pests.
What NOT to Do During Drought
Good intentions can backfire when your landscape is under stress. Avoid these common mistakes to give your lawn and plants the best chance of pulling through.
Don’t Fertilize During Drought
Fertilizer pushes new growth that a water-starved plant simply can’t support, and the salts can chemically burn already-stressed roots. Wait until conditions improve.
Don’t Mow Too Short
Raise your mower height to three inches or more. Taller grass shades the soil, keeps roots cooler, and holds moisture far better than a close-cropped lawn.
Don’t Overwater Dormant Grass
Brown grass is often just dormant, not dead. Cool-season lawns naturally go dormant to protect themselves. A deep soak every couple of weeks keeps the crowns alive without drowning them.
Don’t Remove Plants Too Early
A plant that looks dead may still have living roots ready to push new growth once the rain returns. Give it a full season before deciding to pull anything out.
Recovery After Drought
When the rains return, a little patience and the right timing help your landscape bounce back stronger than before. Focus your recovery efforts on the cooler weeks of fall.
Lawn Recovery
Overseed thin or bare patches in early fall, when soil is still warm and cooler air favors germination. Follow with a fall fertilizer to rebuild root reserves heading into winter. Resume regular deep watering to coax dormant grass back to life.
Plants & Beds
Assess plant survival by scratching a stem: green underneath means it’s still alive. Prune away clearly dead wood, refresh mulch beds to the proper depth, and hold off on replacing anything until you’re certain it won’t recover on its own.
When to Call a Professional
When to Call a Professional
Some drought and heat damage is easy to recover from on your own — but certain situations are best handled by a professional landscape team. Here’s when to reach out to Sandvig Services.
Irrigation System Issues
If your system isn’t distributing water evenly, has broken heads, or failed to run during critical heat windows, a professional inspection can identify and fix problems before more plant material is lost.
Large Tree Dieback
Significant crown dieback, bark cracking, or leaning after a drought event can indicate deep structural stress. An arborist assessment is worth it before assuming a tree will recover on its own.
Widespread Lawn Failure
If more than 50% of your lawn looks brown and unresponsive after rain returns, the turf may be dead rather than dormant. A professional evaluation will tell you whether to reseed, re-sod, or wait.
Designing for Drought Resilience
If your property struggles every summer, it may be time to rethink the landscape design — choosing plants, grading, and irrigation layouts that are built for Minnesota’s increasingly hot and dry summers.
Protect Your Landscape Through Every Season
Minnesota summers can be punishing. Sandvig Services provides proactive care plans, irrigation management, and hands-on recovery support so your landscape stays healthy no matter what the season brings.
