Choosing the Right Location

Hydrangea macrophylla prefers to grow in partial shade. Too much sun can scorch the leaves, while too much shade will prevent the flowers from blooming their best. A location that receives morning sun and afternoon shade is ideal.

The soil should be moist and well-drained. Hydrangeas do not tolerate wet feet, so make sure the soil has good drainage. If your soil is sandy or gravelly, you may need to add some compost or other organic matter to improve drainage.

Planting

Hydrangea macrophylla can be planted in the spring or fall. If you are planting in the spring, wait until the soil has warmed up to at least 60 degrees Fahrenheit. If you are planting in the fall, plant at least six weeks before the first frost.

Dig a hole that is twice as wide and as deep as the root ball of the hydrangea. Amend the soil with compost or other organic matter. Place the hydrangea in the hole and backfill with soil. Water thoroughly.

Watering

Hydrangea macrophylla needs to be watered regularly, especially during the first year after planting. Water deeply once a week, or more often if the weather is hot and dry. Mulch around the base of the plant to help retain moisture.

Fertilizing

Hydrangea macrophylla 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.

Pruning

Hydrangea macrophylla should be pruned in the spring, after the flowers have finished blooming. Prune to remove dead, diseased, or damaged branches. You can also prune to shape the plant.

Overwintering

In most climates, Hydrangea macrophylla is hardy to USDA zones 4-9. However, in colder climates, the plant may need to be protected from the cold. In the fall, before the first frost, mulch the base of the plant with several inches of leaves or straw. You may also need to wrap the plant with burlap or other protective material.

Troubleshooting

Leaf scorch: If the leaves of your hydrangea are turning brown, it is likely due to too much sun. Move the plant to a location that receives more shade.

Bud blast: Bud blast is a condition that occurs when the flower buds of a hydrangea are damaged by cold weather. If your hydrangea is in a cold climate, you can protect the bud by covering the plant with a burlap sack or other protective material.

Pests and diseases: Hydrangeas are relatively resistant to pests and diseases. However, they can be susceptible to aphids, spider mites, and powdery mildew. If you see any pests or diseases on your hydrangea, treat it immediately with an appropriate pesticide or fungicide.
