As for water, lavender is quite drought-resistant and does not need much water once it is well rooted. It is important not to overwater the plant as this can cause the roots to rot. Wait until the top layer of the soil feels dry before watering. In summer, it is usually enough to water the plant once a week, depending on weather conditions.
Lavender also needs regular pruning to maintain its shape and encourage healthy flowering. Prune the plant in early spring, before new growth begins, to remove the old, woody branches. This allows more energy to go to the new shoots.
If you live in an area with harsh winters, you can protect the lavender’s roots by applying a layer of mulch around the plant. This helps insulate the roots from cold and keeps the plant from drying out during the winter months.
