Flowering trees, like the Golden Raintree, don't need regular pruning once they're established. The Golden Raintree, which grows to heights of 30 feet when mature, has a naturally domed or "rainbow" shaped top that shouldn't be pruned. However, like any tree, golden raintrees benefit from pruning to cut back crossing limbs, or branches that cross and rub against each other.
While the natural dome of the Raintree doesn't need pruning, there are other characteristics that you will want to pay close attention to when pruning. Limbs and branches that rub across each other can damage bark, leaving your tree open to pests and disease. Limbs that threaten to grow into structures or electrical wiring, or block the view of a driveway may also require pruning. Follow these guidelines because improper pruning, even with good intentions, can kill your tree.
Tips for Pruning Golden Raintree
- Prune crossing branches in the late fall or winter
- Prune diseased or pest weakened branches
- Prune branches that could fall or cause injury or that are poorly attached
- Prune branches when they are small so they heal faster and more effectively
- Use proper pruning tools
- Clean and sanitize your tools before cutting to prevent disease transmission
- Prune first for safety, then for health, last for looks
- When you're deciding what to prune, if the limb is under 5 cm, go ahead, but think twice about pruning branches between 5-cm and 10-cm
- Don't prune or cut a branch wider than 10 cm without an urgent reason (call a professional)
