Hot weather is in the forecast! Here are our top hot weather tips for keeping your yard healthy.

1. Take it slow. Deep soak your landscape so that moisture reaches the roots of your plants. Water slowly and deeply and watch for signs of plant heat stress. Use soaker hoses or drip irrigation if you can or hand water at the base of the plant below the leaves.

2. Prioritize your trees. Give your trees (especially young ones) some extra water and love during this hot weather. Follow these hot weather tree care tips from our friends at Portland Parks and Recreation.

3. Timing is everything. Water early in the morning (before 10 a.m.), when temperatures are cooler and water won't evaporate as much. But if your plants are showing signs of stress, give them an extra drink as soon as possible.

4. Don’t plant or transplant. Hold off on planting or moving plants during high heat to avoid additional stress on the plant. Move potted plants into a shaded area during the heat of the day and keep them well hydrated. Potted plants need more water than plants in the ground.

7. Pull those weeds. Weeds compete with your plants for water and resources. When it cools down in the evening, get those pesky weeds. Doing so will leave more water for the good stuff.

8. Don’t forget—you need water too! Take care of yourself and keep a water bottle close. Take breaks and keep hydrated. If you don’t have access to a cool space, you can find a cooling center, splash pad, or misting station near you.
