Perhaps your love for the Zantedeschia species inspired you to learn how to prune calla lilies in the UK. Did you know that contrary to what most people think, these plants aren’t considered true lilies? If you’re not aware, calla lilies originate in South Africa, where they thrive in soil that’s both rich and moist.
Although they grow in partly shady areas, they also need to get full sun because this promotes flowering. In most cases, you see these immaculate-looking, trumpet-shaped calla blooms used in wedding arrangements, as well as bridal bouquets. While most of its flowers are white, Callas can also come in a variety of colours.
Tips in Pruning Calla Lilies
Tip #1. Prune your calla lilies after their blooms have withered
When it comes to pruning, timing is vital. Be sure to start the process only after you see the calla blooms wither. Get your tools pruning tools out once you notice that the flowers have already grown fully and have released their distinctive heavy scents.
Tip #2. Don’t prune more than 1/3 of the calla lily stem each year
If you want to eliminate potential blooms, avoid pruning during the late part of autumn or the early part of spring. In most cases, the calla lily bush has about 8 to 12 stems of different ages, with about 1 to 2 inches in diameter. Keep in mind that you shouldn’t be pruning more than 1/3 of its stem each year.
Tip #3. Remember to remove the dead branches
If you’re not aware, the most basic type of pruning involves removing dead branches. During springtime, it’s best to get rid of the shrub’s dead branches that look like they won’t likely live through the punishing winter weather. Except for cases where a major stem or an entire branch is dead, you’ll only need to cut off the dead parts.
Tip #4. Use a sharp knife to cut the dead stems
As mentioned earlier, one needs to eliminate only the dead parts. You can chop them off with a sharp knife so that you won’t be able to crush the healthy branches.
Tip #5. Give the calla lily shrub its proper shape
Once you’ve successfully cut off each stem and branch that has no signs of life in them, it’s time to give your calla lily shrub its proper shape. It’s important to note that in some cases, the branches tend to grow in a way that causes them to rub against each other.
For this reason, it’s best to prune the branches that grow taller than the other branches. To do this right, you need to cut above the node to bring it back to a decent length.
Tip #6. Remove the grown flowers.
If you want to help your calla lilies bloom much better, you need to deadhead them by getting rid of the grown flowers. Failure to remove them will cause your plant to waste most of its energy on seed production. Conversely, deadheading your calla lilies by snipping the flowers off once you see them starting to fade will help you make sure that it will produce more flowers in the next season.
