In this article, we will discuss the best time to prune lavender plants in New Zealand and the proper pruning techniques to use.
When Do You Prune Lavender Plants In Nz?
The optimal time to prune lavender plants in New Zealand is in late summer, after the plant is done blooming. This usually happens around February or March. It’s important to prune lavender before new growth starts in the spring so that the plant doesn’t waste energy producing shoots that will then be removed during pruning.
To begin pruning, gather a pair of sharp pruning shears or scissors. Carefully trim off the top third of the plant, being careful not to cut too much off the woody stem. This will help the plant keep a nice, rounded shape.
Next, lightly shear the sides of the plant, taking care not to cut into the woody stems. It’s important to cut back any long or straggly growth to encourage the plant to produce new growth and prevent it from becoming leggy.
After pruning, it’s important to dispose of any clippings or debris to prevent the spread of disease. You can compost the clippings if you’re sure they are disease-free.
It’s also a good idea to fertilize lavender plants after pruning to promote healthy growth. Use a slow-release fertilizer formulated for woody shrubs, and follow the instructions on the label.
In conclusion, pruning lavender plants in New Zealand should be done in late summer to early autumn, after the plant is done blooming. Be sure to use sharp pruning shears and follow proper pruning techniques to keep the plant healthy and looking its best. And don’t forget to fertilize after pruning to promote healthy new growth. By following these simple tips, your lavender plants will thrive in your garden for years to come.
