Choosing the right location

Star hydrangeas prefer full sun to partial shade. They will tolerate full sun in cooler climates, but they may need some afternoon shade in hot, dry climates. Star hydrangeas also prefer moist, well-drained soil.

Planting and fertilizing

Star hydrangeas should be planted in the spring or fall. When planting, dig a hole that is twice the width and depth of the root ball. Backfill the hole with a mixture of native soil and compost. Water the plant well after planting.

Star hydrangeas should be fertilized once a year in the spring. Use a balanced fertilizer, such as 10-10-10. Apply the fertilizer according to the directions on the label.

Watering and pruning

Star hydrangeas need regular watering, especially during the first year after planting. Water the plant deeply once a week, or more often during hot, dry weather.

Star hydrangeas should be pruned in the spring, after the flowers have faded. Prune the plant by removing any dead, diseased, or damaged branches. You can also prune the plant to shape it or to control its size.

Pests and diseases

Star hydrangeas are relatively resistant to pests and diseases. However, they can be susceptible to aphids, scale, and powdery mildew. If you see any pests or diseases on your star hydrangeas, treat them immediately with an appropriate pesticide or fungicide.

Overwintering

In cold climates, star hydrangeas may need to be protected from the cold in winter. To overwinter your star hydrangeas, mulch the soil around the plants with a thick layer of organic matter, such as leaves or bark. You may also need to cover the plants with a burlap sack or other protective covering.
