Deeply and only when needed.
- Monitor soil moisture. If the first 2.5. cm (inch) or so is dry, you need to water. Reduce frequency of watering when there is a lot of rainfall.
At the base of the plant
- Water at the base of individual plants. Don’t spray leaves. Wet leaves can cause disease.
Early in the day
- Water early in the day if you can. This helps keep water in the ground instead of evaporating into the air.
Gently
- Spraying the soil with too much force can damage soil structure, expose roots and harm seedlings. Try not to splash water up onto the leaves.
