The best time to prune a weeping willow (Salix babylonica), sometimes called a Laura Pendulum, is
in late winter or early spring, before new growth emerges.
Here's why:
* Dormant Pruning: Pruning during this period minimizes stress on the plant and allows it to focus its energy on new growth.
* Avoid Spring Sap Flow: Pruning during the spring, when sap is flowing, can lead to excessive bleeding.
* Shape and Structure: Pruning in late winter helps you better see the plant's structure and shape, making it easier to prune for desired form.
However, you can also prune throughout the growing season to remove dead or damaged branches.
Here are some additional tips for pruning your weeping willow:
* Remove dead, diseased, or damaged branches.
* Thin out branches to improve air circulation and sunlight penetration.
* Prune to shape the tree, but avoid removing more than 1/3 of the plant's foliage in a single year.
* Use clean, sharp pruning tools.
* Make cuts at a 45-degree angle just above a bud or branch collar.
* Don't prune in late summer or fall, as this can encourage new growth that may not have time to harden off before winter.
Remember: Always research the specific pruning needs of your weeping willow variety as there can be slight variations.
