watering

Smooth hydrangeas (Hydrangea arborescens 'NCHA2' INVINCIBLE SPIRIT II) should be watered twice a week, ensuring the soil remains moist but not saturated. During the summer or in drier climates, water more often – up to every day – during periods of no rainfall. During fall and winter, water less frequently, providing enough moisture to avoid wilted leaves, but not saturating the soil. For container-grown plants, check the soil daily for moisture and water as needed.

sunlight

Smooth hydrangeas (Hydrangea arborescens 'NCHA2' INVINCIBELLE SPIRIT II) do best in bright indirect sunlight or partial shade. They require at least 4 to 5 hours of direct sunlight per day. However, direct sunlight during the hot afternoon sun should be avoided, as this can scald the leaves. Combinations of morning sunshine and dappled shade in the afternoon should help the plant thrive.

pruning

Smooth hydrangea plants should be pruned in late winter or early spring when the plant is still dormant. In most cases, the floral buds for the next year are usually formed in the current growing season. Pruning before the buds form will reduce flowering for the next season. Pruning for smooth hydranagea plants should be done with careful attention and minimal pruning. Only select stems that are dead, diseased, or crossed should be removed. Also, take note not to remove more than 1-third of the whole plant. This will help maintain a healthy, full plant and promote lots of blooms in the next season.
