The right time to prune weigela

La ideal time for pruning it's fair after the main flowering, which usually happens between late spring and early summer (usually in June or July). Why is this so important? Because the flower buds develop in autumn to bloom the following year. If you prune in fall or early spring, you could be removing the buds that bear future flowers.
- Pruning after flowering (June or July): Ideal for maintaining shape and stimulating flowering next year.
- Maintenance pruning in late winter: Only if you need to remove dead, weak or very old branches.
Avoid pruning weigela in fall or early spring if you don't want to reduce flowering. Only perform drastic pruning in the off-season when the shrub is severely damaged.
Techniques and steps to prune weigela correctly
Now let's get down to practical matters. How do you prune a weigela step by step? Please note that the technique varies slightly depending on the objective (maintenance, rejuvenation or training):
- Wait until flowering is over and make sure the flowers have completely withered before touching the scissors.
- Check the general condition of the bush, locating dead, damaged, or diseased branches. These will be the first to be removed.
- Cut off branches that have flowered about 40 cm from the end, making the cut just above a bud facing away from the bush. This helps future growth take an open, airy direction.
- Remove the inner branches that are crossed, grow towards the center or are too close together to avoid excessive density and improve air circulation.
- Give it the desired shape the shrub, balancing size and symmetry. If you're looking for a formal hedge or a specific shape, trim only as much as necessary to maintain the look.
- Perform rejuvenation pruning Every few years, shorten the oldest branches to the base (15-20 cm from the ground) if the shrub is very bare or flowering has decreased significantly. Keep in mind that after severe pruning, there will be fewer flowers that year, but the plant will appreciate it in the medium term.
- Disinfect your tools before and after using them, especially if you have cut diseased branches, to avoid infecting other specimens.
Tips for a perfect cut: Always use clean, sharp pruning shears to avoid tearing the stems. Make cuts at a 45-degree angle, just above a shoot or bud facing outward. This will help the wound heal faster and the new growth will be more aesthetically pleasing and healthy.
Pruning according to the condition and age of the shrub
Not all weigelas need the same type of cut. The condition and age of the shrub determine the intensity of pruning.:
- Young weigelas: It only requires cutting tips to form the structure and removing weak branches.
- Adult weigelas (3-5 years): Perform annual maintenance pruning to control size and shape after flowering.
- Aged or neglected weigelas: If the center is very clear or the tips have lost vigor, it is advisable to trim rejuvenation pruning, removing old branches from the base.
If the bush is very untidy or hardly blooms, do not hesitate to cut all the branches back to a few 30 cm above the groundAlthough you'll have fewer flowers that year, you'll be rewarded with younger shoots and much denser blooms in subsequent seasons.
