How often should I water my garden hydrangea?

The Magical garden hydrangea loves moist soil. Hydrangeas in pots need regular water, and so do those in the ground. This is especially important during warm periods. It’s better to give the plant plenty of water a few days a week rather than a little every day. And make sure you keep the flowers dry when watering. On warm days it's best to water early in the morning or in the evening. This is when the plant is 'resting' and can absorb the water best. A well-drained soil also helps.
