Summer is peak season for growth—and stress. High temperatures, intense sunlight, and unpredictable rainfall mean your garden needs thoughtful attention. The most important aspect of summer plant care? Proper watering.
Watering at the wrong time or in the wrong way can cause more harm than good. Here’s how to keep your plants hydrated, happy, and thriving all summer long.
When to Water Plants During Summer
The best time to water your garden in the summer is early morning. This gives your plants plenty of time to absorb moisture before the sun evaporates it and allows the leaves to dry out—helping prevent common fungal diseases.
Avoid watering in the heat of the day when most of the water will evaporate, or in the evening when leaves stay damp overnight, increasing the risk of plant disease.
How to Water for Healthier Plants
Good plant care starts with watering the right way:
- Water the soil, not the leaves. Wet leaves invite fungal infections like powdery mildew and black spot.
- Water deeply and less frequently. A deep soak encourages roots to grow deeper, making plants more drought-resistant.
- Use mulch. A layer of mulch retains soil moisture and regulates temperature.
- Check containers more often. Potted plants dry out faster—especially in full sun. They may need daily watering during heatwaves.
Additional Summer Plant Care Tips
- Watch for signs of dehydration: wilting, yellowing, or dry leaf edges.
- Adjust watering based on rainfall and plant type—some need more, others less.
- Group plants with similar watering needs to simplify your routine.
Proper watering is one of the most powerful ways to improve your summer plant care routine. When done right, it keeps your garden looking lush and resilient, even through the hottest days.

Bonus tip:
If you’re going out of town and won’t be able to water your plants, pull your outdoor plants into the shade and water them very well before you leave. If you can, set them in plastic saucers full of water while you’re away. Or, if you are taking a longer trip, we have an experienced and versatile staff that can assist you!
