Choosing the Right Location

White snowball hydrangeas prefer full sun to partial shade. They will tolerate full shade, but their flowers may not be as large or as abundant. If you live in a hot climate, you may want to choose a location with morning sun and afternoon shade.

White snowball hydrangeas also prefer well-drained soil. They will tolerate some clay soil, but they will not do well in soggy or poorly drained soil. If you have clay soil, you can improve drainage by adding organic matter such as compost or peat moss.

Planting

White snowball hydrangeas can be planted in the spring or fall. If you are planting in the spring, it is best to do so as soon as the soil can be worked. If you are planting in the fall, it is best to do so in early fall so that the roots have time to establish before the ground freezes.

When planting, dig a hole that is twice as wide and as deep as the root ball of the hydrangea. Backfill the hole with soil, being careful not to bury the crown of the hydrangea. Water the hydrangea well after planting.

Watering

White snowball hydrangeas need regular watering, especially during their first year in the ground. Water deeply once a week, or more often if the weather is hot and dry. Mulching around the hydrangea will help to conserve water and keep the roots cool.

Fertilizing

White snowball hydrangeas do not need to be fertilized often. A light application of a balanced fertilizer in the spring will help to promote new growth and flowering. You can also use a fertilizer specifically formulated for hydrangeas.

Pruning

White snowball hydrangeas do not need to be pruned heavily. However, you may want to remove any dead, damaged, or diseased branches in the spring. You can also prune the hydrangea to shape it or to keep it from getting too large.

Overwintering

White snowball hydrangeas are hardy in zones 3-9. In colder climates, you may want to protect the hydrangea from winter winds and cold. You can do this by covering the hydrangea with a burlap sack or by wrapping it with a layer of insulation.

Troubleshooting

If your white snowball hydrangea is not blooming, there are a few possible reasons. First, make sure that the hydrangea is getting enough sun. Second, check the soil moisture. Hydrangeas need regular watering, especially during their first year in the ground. Third, make sure that the hydrangea is getting enough fertilizer. A light application of a balanced fertilizer in the spring will help to promote new growth and flowering.

If your white snowball hydrangea's leaves are turning yellow, it may be a sign of a nutrient deficiency. Try fertilizing the hydrangea with a fertilizer specifically formulated for hydrangeas. If the leaves are still yellow after fertilizing, you may need to have the soil tested to determine what nutrients are lacking.
