Best Types of Tree Hydrangea

If you’re someone who loves gardening and falls into the golden age group of 45-65 years old, then growing a hydrangea tree might be the perfect project for you. The best part is, it’s much easier than you might think! Let’s take a look at some essential tips to help you get started.

There are several types of tree hydrangeas to choose from, each with its own unique characteristics. Here are a few popular ones that you might consider:

  • Hydrangea paniculata ‘Grandiflora’: This variety can grow up to an impressive 25 feet tall and boasts beautiful pure white flowers.
  • Hydrangea paniculata ‘Limelight’: With a more modest height of 6 to 8 feet, this tree hydrangea produces lovely greenish flowers.
  • Hydrangea paniculata ‘Big Ben’: If you have a smaller garden, this dwarf variety is perfect, reaching only about 3 feet tall.
  • Hydrangea paniculata ‘Bobo’: Known for its stunning bicolor flower heads, this variety can grow up to 8 feet in both height and width.
  • Hydrangea paniculata ‘Pinky Winky’: This tree hydrangea stands tall at a maximum height of 8 feet and offers unique flower clusters in deeper pink colors.

Proper pruning is essential for maintaining a healthy hydrangea tree. Follow these simple tips for the best results:

  • Trim your tree during late winter or early spring, before the new growth begins.
  • Thinning out the shrub to five to ten main stems will encourage larger flower clusters.
  • If you prefer a tree with a single trunk, select a main stem and attach it to a sturdy stake. This will help the trunk grow taller and give it a more tree-like appearance.

If you want to expand your collection of tree hydrangeas, you can propagate them by taking cuttings. Here’s a step-by-step guide:

  1. Select a healthy stem that hasn’t bloomed yet and snip off a 6-inch section.
  2. Remove the lower leaves and cut the remaining leaves in half lengthwise.
  3. Dip the cuttings in rooting hormone and plant them in small containers filled with vermiculite, coarse sand, or a mix of both.
  4. Keep the soil slightly moist and cover the container with a plastic bag or dome to retain moisture.
  5. Place the container in a bright spot with indirect light and wait for about a month for the cuttings to develop roots.

Growing hydrangeas from seeds can be a bit more challenging, but if you’re up for the task, here’s what you need to do:

  1. Allow some flowers to develop on the plant and then harvest them, letting them dry in paper bags.
  2. After about a week, shake the bag to separate the tiny seeds from the flower heads.
  3. In the fall, you can sow the seeds directly into the ground or start sowing indoors in early spring.
  4. Spread the seeds over the surface of a container filled with potting soil and keep the soil slightly moist.
  5. Place the container in full sun and expect the seeds to germinate within a few weeks.

If you have a container-grown hydrangea, here are a few tips for repotting:

  • Spring or winter is the best time to repot your hydrangea.
  • Choose a slightly larger container with good drainage.
  • Use a mix of compost and a hydrangea-specific fertilizer as the growing medium.
  • Place the container in a shaded area for a few days before gradually exposing it to more sunlight.

To ensure that your hydrangea tree thrives, keep these tips in mind:

  • Hydrangeas prefer a balance of full sun and partial shade. In cooler climates, more sun is beneficial, while in warmer climates, partial shade works best.
  • Keep the soil moist but not overly wet. Avoid letting the soil dry out completely, as it can cause the leaves to wilt.
  • Hydrangeas thrive in slightly acidic soil but can tolerate alkaline soils as long as they are well-drained and rich in organic matter.
  • They can be grown in hardiness zones 3 through 8 and do well in areas with average humidity. In warmer climates, providing shade is recommended.
  • Fertilize your hydrangea once in early spring and again after the flowers fade in autumn. Adding compost in the summer will also benefit the tree’s growth.

Growing a hydrangea tree is a rewarding and enjoyable process that will add beauty and elegance to your garden. So grab your gardening tools and follow these tips to grow a stunning tree that will bring joy for years to come!
