bigleaf hydrangea

Bigleaf hydrangea (Hydrangea macrophylla 'P11HM-11' BLOOMSTRUCK) should be watered once a week when the soil is dry, usually about 1 to 1.5 inches below the surface. To determine whether the soil is dry, stick your finger into the soil up to the second knuckle or until it reaches the first knuckle. If the top inch of soil is dry, it’s time to water. Avoid over-watering as it can cause root rot and other problems. When watering, pour water slowly and deeply over the root zone of the plant until the soil is saturated, and allow the soil to dry out in between watering.

Bigleaf Hydrangea (Hydrangea macrophylla 'P11HM-11' BLOOMSTRUCK) need an average of at least 5-6 hours of sunlight per day to thrive. However, it is important to avoid placing the plant in an area where it will receive full sun all day, as this can be too intense and can scorch the foliage or cause other damage to the plant. The best spot for a Hydrangea is 1 with morning sun preferably followed by light shade during the hottest times of the day. If your area gets more than 6 hours of direct sunlight, placing the plant in a light filtered area where the sunlight is not so intense is recommended.

Bigleaf hydrangeas should be pruned in late winter, just before new growth emerges in the spring. Remove any dead or diseased branches and thin out overcrowded areas of the plant. Pruning large branches should also be done in late winter. For best bloom production, remove about 1 third of the oldest shoots. Avoid cutting back too severely as this can damage the plant and reduce blooming. For a more compact bush, prune plants to the desired shape immediately after blooms have faded. Deadheading in the summer will encourage rebloom.
