In gardening, few flowers can match the timeless elegance and charm of the hydrangea. Whether they grace the landscape with their cascading blooms or stand tall as tree beauties, these flowering wonders will captivate gardeners with their versatility and grace. Hydrangea cultivation involves a combination of art and horticultural knowledge, offering enthusiasts a variety of techniques to grow and propagate this charming flora.
Careful removal of excess soil from the root ball is crucial when transitioning or overgrowing hydrangea plants. Exposing the base and roots of the plant makes it easy to make strategic cutting points, which are essential for encouraging the growth of other shrubs and providing firm support with sturdy roots for the sides of the tree. This method lays the foundation for better survival rates and successful cultivation, allowing hydrangeas to flourish as multiple thriving entities.
The best tree varieties of hydrangea
Tree hydrangeas come in different varieties:
The pure white flowers of Hydrangea paniculata ‘Grandiflora’ grow to 25 feet tall and 10 feet wide.
The greenish flowers of Hydrangea paniculata ‘Limelight’ grow 6 to 8 feet tall and 5 to 7 feet wide.
Prized for its deep pink flowers, Hydrangea paniculata ‘Big Ben’ reaches a height of 6 to 8 feet as well as a width of 5 to 7 feet.
The dwarf variety Hydrangea paniculata ‘Bobo’ only grows to about 3 feet tall and wide.
With a maximum height and width of eight feet, Hydrangea paniculata ‘Pinky Winky’ is known for its two-tone flowers that are pink on the bottom and white on top.
Vanilla Strawberry: Height: 7 to 10 feet
Cropping
This plant can be made into a small tree by clever pruning. But when grown as a large bush with several stems, it looks best. Flowering occurs when the current season’s growth (new wood) is developing. So prune as needed between late winter and early spring. Some flowers that grow that season may not come back if you cut them too soon. If the bush is thinned to five to ten main stems, it will continue to produce larger clusters of flowers when kept in bush form.
Select the main stem and secure it to a sturdy stake to train the plant to grow like a tree. Cut the stems of your opponent’s land. After the main stem is about three-quarters of the way above the ground, remove any buds that stick out. Continue to scan the area around the base of the plant for buds and remove them as they develop. Your main trunk resembles a tree trunk as it keeps growing and has leaves on top. It can take up to two years to get a tree in the right shape.
Growing hydrangeas
Cuttings are one method of propagating tree hydrangeas. Before the plants bloom, the spring or early summer is the perfect time to do this. Not only can you grow more plants for less money with cuttings, but you can also grow more of your preferred varieties of tree hydrangea.
1. Using sharp, sterile scissors, cut off a section of healthy, non-flowering stem about 6 inches long.
2. Cut the remaining leaves in half lengthwise and remove the leaves under the cuttings.
3. After dipping the cuttings in the rooting hormone, immediately plant them in small containers filled with either coarse sand, vermiculite, or a combination of both.
4. Water the cuttings, being careful not to overwet the soil.
To keep moisture inside the container, cover it with a plastic bag or dome. Be careful not to let the plastic get into the cutout.
5. Place the container so that bright indirect light falls on it.
Keep the soil slightly moist but not soggy. Cuttings should take about a month to form a root system. It can then be moved.
How to plant a hydrangea seed tree
Growing hydrangeas from seed is doable, but be aware that it can be challenging. So most gardeners decide to use cuttings for propagation.
If you choose to propagate from seed, give the plant time to produce several flowers. The flowers are collected in paper bags after a few months. Now they can have time to dry. To ensure the flower heads are dry, keep them in the bag for another week. Then shake the bag well. This will help separate the flower heads from the tiny seeds. Note that these seeds can be hard to find as they are about the size of a grain of pepper or salt.
The seeds can be sown directly in autumn, or if they survive the winter they can be started indoors in early spring. After adding the soil to the container, spread the seeds evenly on top. Do not bury them in the dirt. Keep the soil slightly moist. After placing the container in direct sun, the seeds should begin to germinate in a few weeks.
Transplanted and potted hydrangeas in tree form
Depending on the size of the pot, container-grown hydrangeas may require repotting every two years as they mature. Transplanting hydrangeas is best done in the spring when the plants are not yet stressed by the summer heat but have gone through a dormant period. To give the hydrangea more time to acclimatize to the new environment, you can also transplant it in winter.
Choose a container that is slightly larger than the one used before. Unglazed clay works best for containers because it allows excess soil moisture to escape through the walls. If you are watering a hydrangea for the first time, use a pot with a diameter of 20 to 30 cm. Compost thoroughly mixed with a hydrangea-specific fertilizer is an ideal growing medium. When planting, fill the stems and roots with soil. Keep the container in the shade for the first few days. Then gradually open it to more sunlight so the plant can get used to the light and humidity. Do not allow the soil to become waterlogged.
Keep the soil moist until it freezes to help the plant survive the winter. Add three to four inches of mulch to the roots, but be sure to remove it once the weather warms.
Brightness
Paniculatas prefer partial shade and full sun. Whether your hydrangea needs more sun or more shade depends in part on your local climate.
Hydrangeas thrive in full sun in cooler climates and partial shade in warmer climates.
Ideally, they should get at least four hours of direct sunlight each day. When the buds are not exposed to the strongest light during the day, they usually last longer.
Water
Each variety of hydrangea prefers moist to slightly moist soil. The leaves will drop and wilt if the soil dries out completely.
It is important that you keep the soil hydrated during summer and heat waves, although your hydrangeas will naturally receive plenty of moisture during the spring and summer when rainfall is good.
Hydrangeas are best watered with a hose, making sure to wet only the roots and avoid getting water on the leaves.
Water that remains on the leaves for an extended period of time can promote bacterial and fungal infections. It is therefore ideal to water in the morning and let the leaves dry until the evening.
Soil
Although they can grow in alkaline soils as long as they are well-drained and rich in organic matter, hydrangeas prefer slightly acidic soil.
Ensuring adequate drainage is essential to prevent hydrangea roots from becoming waterlogged and rotting.
Humidity and temperature
Hardiness zones 3 to 8 are suitable for hydrangea growth. They have much more energy than other breeds.
In warm climates, they grow well in average humidity and benefit from shade.
Application of fertilizers
Fertilization is not necessary for hydrangeas. Fertilize once in early spring and once in fall when the flowers have faded. Composting in summer improves soil quality for hydrangea plants.
Different formulations and dosing recommendations are available for hydrangea fertilizers. It may be necessary to use some weaker solutions every two weeks.
Make sure the dosage is followed to avoid burning the fertilizer and damaging the crop.
