Weigelas are pretty, deciduous shrubs that are well-loved for their prolific pink, purple, white, or red springtime blooms. Due to their fast and often-sprawling growth habit, an annual trim can be beneficial to keep their size in check.
Pruning these flowering shrubs also allows you to remove any dead or diseased limbs, and open up more congested areas, too. All of this will improve the overall health of the plants and encourage lush growth and more blooms to brighten your yard.
When to prune weigela
Routine pruning to control the shape and size of your weigela can be carried out once a year.
It's important to note that these plants flower on the previous year's wood. So, wait to prune until late spring or early summer, after they have finished blooming, advises gardening expert Janet Loughrey of Garden Design. 'This should be done as soon as possible, as plants will begin forming new flower buds that will bloom the following year.
'Dead, diseased, or broken branches can be removed at any time during the growing season,' she adds.
How to prune weigela
Weigelas often look best when allowed to retain a somewhat natural shape, says Janet. So, bear this in mind as you prune.
'Before you begin, make sure you have sharp and clean pruning shears or loppers,' advises Harry Luther, the Founder of PlantPat. 'This will help you achieve clean cuts and minimize any potential damage to the plant.'
Begin by removing any dead or diseased stems, pruning them out at the base, says Harry. Then, cut back any errant stems that cause the plant to look misshapen, Janet instructs. 'Prune back to a healthy set of lateral shoots, which will promote lush, vigorous growth and more flower buds,' she says. Try to make your cuts at a 45-degree angle.
Every few years, you can also remove some of the old, thick, woodier branches by cutting them back to the base. This will help to rejuvenate the shrub and encourage better airflow and more sunlight into the plant.
When shaping or rejuvenating your shrub, remember to stick to the one-third pruning rule to avoid shocking it.
Once you've finished pruning your weigela, it's important to provide aftercare. 'Be sure to water the weigela well and add a layer of mulch around the base to retain moisture and suppress weeds,' Harry recommends. This will help it to recover quickly.
Add pruning weigela to your gardening tasks checklist and you'll be rewarded with a beautiful shrub that will bring plenty of blooms to your yard spring after spring. And while you have your pruners to hand, why not tackle a few other spring-flowering shrubs, too? Lilacs and viburnums, for instance, can also benefit from a trim once their flowers have finished.
