The Empress Tree (Paulownia) is famous for being low-maintenance and a stunning addition to any backyard. But if you want that picture-perfect canopy, a little strategic pruning goes a long way. Not only does it keep the tree looking its best, but it also encourages healthy, natural growth. Here’s the lowdown on how to prune your Empress Tree like a pro.
Strategic Pruning Boosts Natural Growth
The Empress Tree is a seriously fast grower—we’re talking impressive annual growth rates. Because it’s so vigorous, it can actually handle a pretty radical pruning; even if you go a bit overboard, it’ll bounce back with new shoots. However, timing is everything. You want to prune when the tree can use its natural growth spurt to heal quickly without leaving it vulnerable to the cold.
Here’s what you’ll need in your gardening kit:
- A sharp pair of pruning shears or loppers
- Gardening gloves
- Tree wound sealer (optional, for larger cuts)
Generally, the sweet spot for pruning is between May and July. This timing ensures the threat of frost has passed, but the tree hasn’t started setting its new buds yet. You definitely want to avoid cutting off the buds of the Paulownia, or you’ll end up with way fewer of those gorgeous purple blooms next season.
Pro tip: If you notice any frost damage when spring rolls around, go ahead and trim those damaged shoots back immediately. If you have to cut back thicker branches during a cold snap, applying a wound sealer can help protect the tree.
Post-Pruning Care for Your Paulownia
When you head out to prune, try to pick a cloudy day rather than one with intense, direct sunlight. Once you’ve finished, the Paulownia is usually pretty good at jumping back into growth mode on its own. That said, a little boost of the right fertilizer can really help support that natural vigor. And don’t forget to keep it hydrated with regular watering!
By combining a good trim with consistent nutrients and water, you’re ensuring your tree stays healthy from top to bottom. Just a heads-up: make sure the soil drains well. These trees hate “wet feet,” and standing water can cause major issues for Paulownia roots, even leading to root rot. If your soil is heavy, adding a drainage layer is a smart move to keep your tree happy.
