smooth hydrangea

Smooth Hydrangea plants require consistent water for the best growth and health. During the first growing season, water regularly to help establish deep and healthy root systems. The plant should receive about 1-2 inches of water per week, applied directly to the soil and not to the leaves. Water deeply and frequently enough so that the soil stays evenly moist. Once the plant is established, water deeply and less frequently, allowing the top few inches of the soil to dry between watering sessions. To check soil moisture, insert your finger an inch into the soil and feel for wetness.

Smooth hydrangea (Hydrangea arborescens 'Green Dragon') does best in bright but indirect sunlight or partial shade. Direct sunlight can cause the leaves to scorch and excessive shade can prevent blooms. To ensure the best blooms and avoid any leaf damage, this hydrangea should receive 3 to 4 hours of sunlight each day in the morning or late afternoon, when the sun’s rays are the least intense.

Smooth hydrangea (Hydrangea arborescens 'Green Dragon') should be pruned once each year, in the late winter or early spring while the plant is still dormant. Pruning should be light, only removing dead, damaged, or overgrown stems. If necessary, you can also remove up to 1-third of the oldest, thickest stems back to the ground level. If you are pruning to keep the shrub small, remove the new shoots with the smallest stems, typically within the center of the plant. Avoid pruning smooth hydrangeas later in the summer or fall, since this can encourage new growth that won't have enough time to harden off before winter.
