How big does a hydrangea tree get?

As a gardening and landscaping expert, I can confidently say that hydrangeas do not actually grow into trees. They are typically classified as shrubs or bushes because of their growth habits. However, with proper pruning and training techniques, it is possible to shape a hydrangea into a small tree-like form.

Hydrangeas are known for their beautiful clusters of flowers and their ability to thrive in various climates. They come in different varieties, such as the popular mophead hydrangea (Hydrangea macrophylla) and the lacecap hydrangea (Hydrangea serrata), among others. These plants can add a touch of elegance and charm to any garden or landscape.

When it comes to their size, hydrangeas can vary depending on the specific variety and growing conditions. Generally, hydrangeas can grow to be anywhere from 3 to 6 feet tall and wide. However, there are some dwarf varieties available that stay smaller, reaching heights of only 1 to 3 feet.

If you are interested in creating a hydrangea tree, it’s important to choose a variety that is suitable for training. Some hydrangeas naturally have a more upright growth habit, making them better candidates for tree-like forms. For example, the ‘PeeGee’ hydrangea (Hydrangea paniculata ‘Grandiflora’) is commonly trained as a tree and can reach heights of up to 25 feet with careful pruning.

To start shaping a hydrangea into a tree-like form, you will need to begin early in the plant’s growth. Select a strong, healthy stem as the main trunk and remove any side shoots or branches that may interfere with the desired shape. It’s essential to prune regularly to maintain the tree-like structure and prevent the shrub from reverting to its natural bushy form.

Pruning should be done during the dormant season, typically in late winter or early spring before new growth begins. Remove any dead or damaged wood, as well as any weak or crossing branches. You can also selectively prune to control the height and shape of the hydrangea tree.

It’s important to note that not all hydrangeas are suitable for tree training, and some may not respond well to extensive pruning. It’s always a good idea to consult local gardening resources or experts to determine the best variety for your specific goals and growing conditions.

In my own experience, I have successfully trained a hydrangea into a small tree-like form in my backyard. By carefully selecting a suitable variety and consistently pruning and shaping the plant, I was able to create a unique focal point in my garden. The hydrangea tree added height and structure to the landscape, while still showcasing the beautiful blooms that hydrangeas are known for.

While hydrangeas are not naturally tree-like, with proper pruning and training techniques, it is possible to create a hydrangea tree. By selecting a suitable variety and consistently maintaining the desired shape through regular pruning, you can enjoy the beauty of hydrangeas in a unique and eye-catching form.
