Once established, lavender is a low-maintenance plant, it is then considered drought tolerant and requires minimal watering. Aim to water the lavender at least once a week in summer. Lavender that you have planted in pots should be watered every second day.
When watering, focus on the soil and try not wetting the foliage.
After flowering you should prune lavender start by cutting back a third of the flower. If your plant is flowering progressively, you can lightly trim it in order for it to look neat.
Pruning promotes new healthy growth so do not be afraid of it.

Lavender bushes typically last between seven and ten years before needing replacing.
Where and when to grow lavender
As lavender is a Mediterranean plant, it does prefer warmer conditions. It is best to plant it in the warmer seasons.
The varieties of lavender thrive best in slightly different conditions depending on how tolerant they are however all lavender likes the sun.
Perfect the pruning
If you want to keep your flowers looking neat and fresh, make sure to prune them into shape once they have flowered.
If the plant becomes woody and dry, cut it back by about half its height in the spring to promote fresh new growth and full-bodied flowers. Make sure when you are cutting back, you cut the flower stalks and not the woody stem.
Plants that aren’t pruned can lose their flowers, so make sure to cut off those dying flowers in summer to encourage repeat blooming throughout the season.
Remember earlier we mentioned how dried lavender can be a component for a variety of things including food, scents and medicinal purposes. In order to obtain these uses, it is best to know how to dry it out but don’t worry its super easy. Here it is explained perfectly by Gardening etc.
- Snip the flowers. Follow the stem down from the flower bud until you reach a junction where two side leaves or new buds have begun to form.
- Snip the stem just there and the plant will continue to produce more fresh flowers. For longer stems, simply snip deeper into the plant.
- The simplest way to dry fresh lavender is to hang it up in small bunches.
- Secure each bunch loosely with twine, then hang them upside down in a warm, dry spot where the air can circulate around them.
- Alternatively dry your bunches of lavender in vases, making sure there is plenty of room for air to circulate around the stems to prevent them going mouldy.
