So what should you pay attention to when pruning lavender?
Lavender pruning time in the cool season such as spring and autumn, generally pruning in the spring, pruning in the fall will affect the cold hardiness. When pruning, be careful not to cut into the woody parts to avoid weakening and death of the lavender plant.
Lavender generally flowers from June to August and must be pruned after its flowering. The plant can be pruned to 2/3 of its original size, and the plant will be sturdier and more conducive to growth.
Lignification is the flowering plants to resist the harsh environment, from grass to wood has evolved, trees are more tenacious than grass life. Due to insufficient ventilation around the roots, or the top of the leaves are not pruned in time resulting in nutrient delivery, the roots and leaves will wither and fade, and lignification of the branches will occur.
The way to prevent lavender lignification is to prune in time, pruning once a week with a length of 0.5cm to 1cm each time.
After the lavender winter, the upper branches gradually withered, must be chime pruned, reducing nutrient consumption, in order to facilitate the next spring’s new sprouting growth.
When pruning, the branches above l0~15cm from the ground are cut off and cut into a conical shape with a low perimeter and a high middle. Generally in early winter or before the freeze combined with soil pruning is better.
Soil cultivation makes adventitious roots occur at the base of the stem, expanding the scope of water and nutrient absorption, facilitating drainage, reducing field density, and mitigating disease, while protecting seedlings safely overwintering.
