Tardiva Hydrangea (tree form)

Tardiva Hydrangea in tree form should be watered once a week in the growing season. It requires an average of 1 inch of water every week during the growing season – April through August. In the cooler months of September and October, you can reduce watering slightly to about 3-quarters of an inch per week.

Make sure to thoroughly water the soil and don't just sprinkle water on the leaves.

Pruning for a Tardiva Hydrangea (tree form) is recommended sometime during late winter or early spring, when the plant is dormant. Pruning of the Tardiva Hydrangea tree form should be done selectively, removing just a few inches of growth each year. In most cases, no more than 3 to 6 inches should be removed from the old woody material surrounding the main stems of the tree. Additionally, any weak or crossing branches should be removed completely. The goal should be to shape the plant by removing only the necessary branches, rather than shearing off too much of the old wood. It is important to remove any dead and damaged wood during the pruning process.
