Royal Empress Trees: A Guide to Pruning and Care
Introduction
Royal empress trees (Paulownia spp.) are fast-growing trees with beautiful lavender flowers. They can grow up to 50 feet tall and wide. To keep these trees healthy and under control, it’s important to prune them properly.
When to Prune
The best time to prune a royal empress tree is in the early spring, before new growth begins. You can also prune in the fall, but avoid pruning in the winter, as this can damage the tree.
How to Prune
There are several different ways to prune a royal empress tree, depending on the desired outcome.
-
To prune into a shorter garden-size plant: Cut the tree back to about 4 feet, leaving a few branches on the main trunk. This will slow the growth of the tree and make it more manageable.
-
To prune severely: Cut the tree back very hard in the winter. This will cause new leaves to open every spring.
-
To strengthen the flowering tree: Cut back dead wood in early spring. After flowering, you can prune more severely to remove damaged and overlapping branches, as well as branches with poor collar attachment.
-
To remove lower branches: Cut off lower branches to allow passage below the tree.
-
To regrow a spindly or crooked tree: Cut the tree back to the ground and allow it to regrow. When it does, prune back all except the strongest shoot.
Pruning Techniques
When pruning a royal empress tree, use sharp, clean pruning shears or a pruning saw. Make clean cuts at a 45-degree angle. Avoid leaving stubs, as these can become infected.
Benefits of Pruning
Pruning a royal empress tree offers several benefits, including:
-
Improved growth: Pruning can help to control the growth of the tree and make it more manageable.
-
Increased flowering: Pruning can encourage the tree to produce more flowers.
-
Reduced risk of disease: Pruning can help to remove dead and diseased branches, which can reduce the risk of disease spreading to the rest of the tree.
-
Improved appearance: Pruning can help to improve the appearance of the tree and make it more attractive.
Additional Care Tips
In addition to pruning, there are a few other things you can do to care for your royal empress tree:
-
Water regularly: Royal empress trees need regular watering, especially during the hot summer months.
-
Fertilize: Fertilize the tree in the spring and fall with a balanced fertilizer.
-
Mulch: Mulch around the tree to help retain moisture and suppress weeds.
By following these tips, you can help your royal empress tree thrive for many years to come.
