Three things to do before next week’s heat

Your fall food garden starts now, even if your current garden looks finished.

Next week, temperatures are expected to climb above 100 degrees in North Texas.

That may not feel like gardening weather, but the next several days are actually important if you want to continue harvesting food this fall.

Here are three things to do now:

1. Water deeply before the worst heat arrives.

Do not respond to extreme temperatures by lightly watering every day. Your goal is to thoroughly wet the soil at least six inches deep, then allow the upper few inches to begin drying before watering again.

Check your beds with your finger or a small trowel. If only the surface is wet, your irrigation system has not run long enough.

2. Start your fall brassicas indoors.

Broccoli, cabbage, cauliflower, kale and related crops need time to grow into sturdy transplants before they go into the garden. Mid-to-late July through the end of August is the time to start these crops indoors under lights. Waiting until the weather feels like fall usually means starting too late. Our Indoor Seed-Starting Master Class is the best course available to gardeners on the subject and is available now for enrolled students inside our course library.

3. Decide what will replace your struggling spring garden.

Tomatoes, cucumbers and squash often look exhausted by this point in the summer. You do not have to keep nursing plants that are no longer productive.

Fall gives us another opportunity to grow tomatoes, cucumbers, squash, beans, root vegetables, leafy greens and much more. But the fall garden must be planned and planted on a North Texas schedule.

The Best-Ever Fall Vegetable Garden replay is now available inside the school.

The class walks you through what to plant, when to plant it and how to establish a productive vegetable garden despite the heat. I even share my personal 2026 fall planting plan with exact planting dates and varieties.

You can watch the replay now and use it to make your planting plan for the rest of the year.
