smooth hydrangea

Smooth hydrangea (Hydrangea arborescens 'Hayes Starburst') plants should be watered on a regular basis, but the exact amount and schedule will depend upon the location and environmental conditions. Water the plants deeply every week or deeper and less frequent when the temperature is above 80°F. If the soil is dry, water the plants more often. During the summer months, the plants need 1–2 inches of water per week, and during the winter, 1 inch of water every 2 weeks is enough. You can also mulch around the plant to help conserve moisture. Make sure the soil is very wet when applying the fertilizer and then allow the soil to dry again before you water.

Smooth hydrangea (Hydrangea arborescens 'Hayes Starburst') should receive full sun for at least 6 to 8 hours each day for optimal growth. This will help to produce high-quality blooms. It can also tolerate some shade and partial shade, although growth and flowers will be reduced in these conditions. It does best in an area with full sun in the morning and partial shade in the afternoon.

Smooth hydrangea (Hydrangea arborescens 'Hayes Starburst') should be pruned once per year, preferably in late winter or early spring before new growth appears. This will help encourage a thicker, bushier growth for the upcoming season. Pruning is best done by removing any dead or diseased stems, cutting back the stems to a pair of healthy buds, and thinning the branches down to an even height. Be sure to use sharp, clean pruning tools to avoid damaging the stems and make the cuts at a 45 degree angle. You can also remove up to 1-third of the oldest stems down to the ground for renewal.
