Lavender plants are quite easy to prune, but there are a few tools you’ll need to gather to get the job done. Below, you’ll find all the essentials.

The best time to prune lavender is in the spring and late summer. You should prune lavender twice a year to help it hold its shape. Lavender should be trimmed after flowering in the summer and again in the spring. Otherwise, the plants can become leggy and woody, which can have a negative impact on its lifespan and ability to grow new blooms.

Lavender only requires a light trim in its first year, though it’s a crucial step in creating the proper shape and encouraging new growth. Fresh lavender plants should be pruned in their first summer, which you’ll learn all about below.

After your lavender plant flowers in the summer, it’s time to prune it. For young and mature plants, the process can be quite different. For both, you’ll need a sanitized pair of pruning shears and gardening gloves.

To prune a new plant, gently cut each stem back by a third, ensuring that there is still plenty of green on the plant. You should also try to create a dome shape to help the plant grow, keeping stems longer in the center and shorter around the sides.

If your plant is mature, the pruning process is a bit easier. Instead of cutting one stem at a time, you can grab handfuls of the plant and snip them off. Again, remove about a third of the stem and leaving plenty of green. Avoid cutting the stems back to the woody base as this can affect how the plant survives through the winter, and its ability to regrow.

Pruning lavender in the spring looks a bit different, but it’s just as important. This should be done early in the spring to ensure the plant has plenty of time to develop new growth. Start by taking a stem and looking for the woody base — its length will depend on the plant’s age and how well it has been pruned in the past.

While you’ll still need a sharp pair of pruning shears, you’ll cut the stem around 2 to 3 inches from the woody base. Again, you can chop handfuls at a time; try to create a rounded shape. Any dead branches should be completely removed.

If you want to harvest the flowers, you should do so in the summer when around half the buds are in bloom. Otherwise, you shouldn’t prune the plant until the flowers have faded. If you want to dry the flowers, tie the stems into bunches and hang them upside down. Also, if you harvest lavender just as it has flowered, you may get a second flush of flowers.

Over time, lavender plants can become more and more woody and leggy. If you notice this, after around three to five years of growing your plant, you may want to cut the plant down and start again from scratch. You can also cut the plant right back to the wood in the spring to give it another chance.
