When to Plant Tree Hydrangeas

Tree hydrangeas are a popular flowering shrub that can add beauty and interest to any garden or landscape. These plants are known for their large, showy blooms that can range in color from white to pink, blue, and purple. If you're considering planting tree hydrangeas in your yard, the timing of when to plant them is critical for their long-term success.

Spring Planting

In general, the best time to plant tree hydrangeas is in the spring, after the risk of frost has passed. This is typically around mid-April in most regions of the United States. By planting in the spring, your hydrangeas will have ample time to get established before the hot summer months arrive.

When planting in the spring, it's important to prepare the soil before digging the hole for your hydrangeas. You'll want to till the soil and add organic matter, such as compost or peat moss, to help improve drainage and fertility. Adding a layer of mulch around the newly planted shrub can also help to retain moisture and suppress weeds.

Fall Planting

If you miss the spring planting window, fall is another good time to plant tree hydrangeas. While planting in the fall may seem counterintuitive, it can actually be a great time to establish new shrubs. The cooler temperatures and increased rainfall can provide ideal growing conditions for your hydrangeas.

The best time to plant in the fall is typically around September or October, depending on your location. However, it's important to plant early enough in the fall to allow your hydrangeas to become well-established before the first hard frost of the season. If you wait too long to plant, your shrubs may not have enough time to establish roots before winter sets in.

Planting Tips

When planting tree hydrangeas, there are a few tips to keep in mind to ensure their success:

Choose a planting location that receives partial to full sunlight, depending on your variety of hydrangea.

Make sure your soil is well-draining and has plenty of organic matter to provide nutrients for your shrubs.

Water your hydrangeas regularly, especially during the first growing season, to help them establish deep roots.

Apply a slow-release fertilizer in the spring to help promote healthy growth and abundant blooms.

Prune your hydrangeas in late winter or early spring to remove dead or damaged branches and to shape the plant for optimal growth.

In conclusion, the best time to plant tree hydrangeas is in the spring, after the threat of frost has passed, or in the fall, before the first hard frost of the season. By following these planting tips and giving your hydrangeas the proper care, you can enjoy their stunning blooms for many years to come.
