Lavender is one of the most popular plants in New Zealand, known for its beauty, fragrance, and versatility. It can be grown in gardens, containers, and even as a hedge. Pruning lavender is an essential part of its maintenance, but many people are unsure when is the best time to do it. In this article, we will discuss everything you need to know about pruning lavender in New Zealand.
Why prune lavender?
Pruning is crucial for lavender as it helps to maintain its overall health and growth. Regular pruning ensures that the plant does not become woody and straggly, and it encourages the growth of new shoots and foliage. Additionally, pruning helps to prevent disease and pests from taking hold of the plant.
When to prune lavender?
The best time to prune lavender in New Zealand is in late summer or early autumn, after its flowering period has ended. This is typically around March or April, depending on the location and weather conditions. Pruning too early can encourage new growth, which may not survive the colder winter months, while pruning too late can affect the plant’s ability to produce new shoots and blooms.
How to prune lavender?
Pruning lavender is a straightforward process, but it requires some care and attention to ensure that the plant remains healthy and attractive. Here are the steps to follow:
Start by removing any dead or diseased branches, cutting them back to the main stem. This helps to prevent the spread of disease and promotes the growth of new shoots.
Using a sharp pair of shears or secateurs, cut back one-third of the plant’s overall height. This should be done by snipping the stems just above a leaf joint or node, to encourage new growth.
If the plant has become too woody or straggly, consider cutting it back more severely. This can be done by cutting back the stems to just a few inches above the ground, which will encourage new growth and rejuvenate the plant.
After pruning, give the plant a good watering to help it recover and start producing new growth.
Tips for pruning lavender
Here are some additional tips to keep in mind when pruning lavender:
- Do not prune lavender in winter or early spring, as this can damage the new buds that are forming.
- Never cut back into old woody growth, as this will not produce new shoots.
- Always use sharp shears or secateurs to get a clean cut, which promotes faster healing.
- If your lavender is overgrown, consider dividing it in early spring to encourage new growth and vigour.
- If you are unsure how to prune your lavender, consult a professional gardener or horticulturist for advice.
Pruning lavender is an essential part of its maintenance, and it can help to keep the plant healthy, attractive, and productive. By following the guidelines outlined in this article, you should be able to prune your lavender effectively and reap the rewards of its beauty and fragrance. Remember, late summer or early autumn is the best time to prune lavender in New Zealand, and always use sharp shears or secateurs for a clean cut. Happy pruning!
