If you\u2019re looking to grow a hydrangea tree, there are a few essential tips you should know. And don\u2019t worry, it\u2019s easier than it sounds!<\/p>\n
Best Types of Tree Hydrangea
\nThere are different types of tree hydrangeas to choose from. Here are some popular ones:<\/p>\n
Hydrangea paniculata \u2018Grandiflora\u2019: This variety grows up to 25 feet tall with a 10-foot spread and has beautiful pure white flowers.
\nHydrangea paniculata \u2018Limelight\u2019: With a height of 6 to 8 feet and a width of 5 to 7 feet, this tree hydrangea features greenish flowers.
\nHydrangea paniculata \u2018Big Ben\u2019: This dwarf variety only reaches about 3 feet tall and wide, making it perfect for smaller gardens.
\nHydrangea paniculata \u2018Bobo\u2019: Known for its bicolor flower heads (pink on the bottom, white on the top), this variety grows up to 8 feet in height and width.
\nHydrangea paniculata \u2018Pinky Winky\u2019: With a maximum height and width of 8 feet, this tree hydrangea has unique flower clusters in deeper pink colors.
\nPruning Tips
\nProper pruning is key to maintaining a healthy hydrangea tree. For best results, follow these pruning tips:<\/p>\n
Trim your tree during late winter or early spring, before the new growth begins.
\nThinning out the shrub to five to ten main stems will produce larger flower clusters.
\nIf you want your tree to have a single trunk, choose a main stem and attach it to a sturdy stake. Remove any competing ground stems and buds protruding from the main stem. This will help the trunk grow taller and look more tree-like.
\nPropagating Tree Hydrangea
\nIf you want to grow more tree hydrangeas, you can propagate them by cuttings. Here\u2019s how:<\/p>\n
Select a healthy stem that hasn\u2019t bloomed yet and snip a 6-inch section.
\nRemove the lower leaves and cut the remaining leaves in half lengthwise.
\nDip the cuttings in rooting hormone and plant them in small containers filled with vermiculite, coarse sand, or a mix of both.
\nKeep the soil slightly moist and cover the container with a plastic bag or dome to retain moisture.
\nPlace the container in a bright spot with indirect light and wait for about a month for the cuttings to develop roots.
\nHow to Grow a Hydrangea Tree from Seed
\nGrowing hydrangeas from seeds is possible but can be challenging. Most gardeners prefer propagating by cuttings. However, if you want to give it a try, here\u2019s what you need to do:<\/p>\n
Allow some flowers to develop on the plant and then harvest them and let them dry in paper bags.
\nAfter a week, shake the bag to separate the tiny seeds from the flower heads.
\nIn fall, you can sow the seeds directly into the ground or start sowing indoors in early spring.
\nSpread the seeds over the surface of a container filled with potting soil and keep the soil slightly moist.
\nPlace the container in full sun and expect the seeds to germinate within a few weeks.
\nPotted and Repotted Tree Hydrangeas
\nIf you have a container-grown hydrangea, it may need to be repotted every two years. Here\u2019s what you need to know:<\/p>\n","protected":false},"excerpt":{"rendered":"
