Much of the world is baking right now. If you're staring at your yard wondering what to save, what to let go, and what you're probably doing wrong, this is for you.

I've been a landscaper and arborist for four years. Every summer I get the same panicked calls: brown grass, wilting hydrangeas, new plantings dying within days. Most of the damage I see isn't from the heat itself. It's from how people react to it.

Here's what actually works.

Stop doing these things immediately

Before we talk about what to do, here's what to quit right now. These are the most common mistakes I see homeowners make when it gets hot, and every one of them makes things worse.

Stop mowing short. When you scalp your lawn in the heat, you expose the soil to direct sun. The ground dries out faster, roots cook, and the grass can't shade itself. Raise your mower to the highest setting, 3.5 to 4 inches for most cool-season grasses. The extra blade length shades the root zone and holds moisture longer.

Stop fertilizing. Fertilizer pushes new growth, and new growth needs water. In extreme heat your grass and plants are already stressed just staying alive. Forcing them to grow right now is like making someone run sprints with a fever. Wait until temperatures drop below 85°F consistently.

Stop watering in the afternoon. Watering when the sun is highest means most of it evaporates before reaching roots. You waste water and your plants stay thirsty. Worse, water droplets on leaves in direct sun can magnify heat and scorch foliage.

Stop planting. This is not the time to install that new garden bed. Transplants have small, undeveloped root systems and can't pull enough water from hot soil to survive. Wait for fall. Honestly, fall is the best planting season anyway, and I'll write about why in a future post.

What to do this week

Water deeply, not often

This is the single most important thing. One deep soak is worth ten light sprinkles.

Light watering wets the top inch of soil, which dries out by noon. Roots stay shallow because they never need to reach down for moisture. Deep watering (30 to 45 minutes with a sprinkler, or a slow drip for an hour) pushes water 6 to 8 inches into the ground. Roots chase it down, and deeper roots survive heat far better.

Water two to three times per week, early in the morning before 8 AM. That's it. Your lawn might still look stressed, but the roots will be alive and ready to bounce back when temperatures drop.

Mulch everything

If you only do one thing from this list, mulch your beds. Two to three inches of organic mulch (shredded bark, wood chips, or even shredded leaves) does three things at once: holds moisture in the soil, keeps root zones 10 to 15 degrees cooler than bare ground, and breaks down slowly into organic matter that improves soil over time.

Keep mulch a few inches away from tree trunks and plant stems. Piling it against bark traps moisture and invites rot and disease.

Prioritize what matters most

You can't save everything in extreme heat, and you shouldn't try. Here's how to triage:

Save first: Trees and established shrubs. These represent years of growth and real money. A dead tree costs hundreds or thousands to remove and decades to replace. Give them a long, slow soak once a week. Even mature trees with deep roots can struggle in prolonged heat.

Save second: Perennials and anything you planted this year. New plantings are the most vulnerable because their roots haven't spread yet. Water these every other day if they're wilting.

Let go if needed: Annual flowers and your lawn's color. Lawns are built to go dormant. The brown doesn't mean dead. Most turf grasses can survive four to six weeks of dormancy and green back up with rain. Annuals are one-season plants by definition. If they crisp, replace them for a few dollars in the fall.

Check your irrigation system

If you have sprinklers or drip lines, now is the time to actually watch them run. Walk the yard while they're on. Look for:

Heads that are clogged, crooked, or spraying the sidewalk instead of the bed

Dry spots between sprinkler arcs (overlap should be head-to-head)

Drip emitters that have popped off or gotten buried in mulch

Timer settings that are still on a spring schedule

Fifteen minutes of checking can fix weeks of uneven watering.

Thinking longer term

If this heatwave has you rethinking your yard, that's a good instinct. Summers are getting hotter in most places, and yards that were designed for a different climate are going to keep struggling.

A few things worth considering once the heat breaks:

Native plants aren't just trendy, they're practical. Plants that evolved in your region are already adapted to its heat, its rainfall patterns, and its soil. They need less water, less fertilizer, and less babying than ornamental imports. A yard full of native plants isn't zero-maintenance, but it's dramatically less work in extreme weather.

Reduce lawn area gradually. I love a nice lawn, but turf grass is the thirstiest, most maintenance-heavy thing in most yards. Replacing even a small section with native groundcover, mulched beds, or a gravel path cuts your water use and gives you less to worry about next time.

Group plants by water needs. Landscapers call this hydrozoning. Put your thirsty plants together near a water source, and your drought-tolerant plants together where they can fend for themselves. This way you're not overwatering tough plants or underwatering needy ones.

The bottom line

Heatwaves are stressful for your yard and for you. The best thing you can do right now is stop doing damage (no mowing short, no fertilizing, no afternoon watering), focus your water where it counts most (trees and established plants, deep and early), and mulch everything you can.

Your lawn will probably go brown. That's fine. It will come back.

And if this summer has you thinking about redesigning for something that handles heat better, that's exactly the kind of thing we built Easy Landscape Design to help with. Upload a photo of your yard and we'll show you what it could look like with plants that actually thrive where you live. No sales pitch, just a starting point you can take to your local nursery when the weather cools down.

Stay cool out there.
