Pruning of lavender
The pruning of lavender is generally performed to guarantee the plant a balanced and harmonious growth. At the beginning of the flowering period, one can begin to think of pruning, since lavender has started the vegetative phase and there is therefore no danger of causing damage to its development. Usually two thirds of the vegetation born during the previous months are eliminated, in addition to the dry parts represented by the ears. A good pruning of lavender should be done in the middle of the foliage, taking care to leave at least four buds for each stem. The plant will remain bare for a few weeks but this operation is necessary to ensure its health. At the end of September, lavender will already be uniform and compact, ready for a new flowering. Moreover if well cared for, this species is able to survive for long years without losing its natural beauty. To obtain this result, lavender pruning should be done without cutting too much and leaving the old wood where the buds grow intact.
How to make cuts during pruning
Since the lavender reproduces on new wood, if the old wooden parts are cut, the plant could die, as it lacks new buds. It is very important to make exact cuts when pruning lavender using even the most suitable tools for this operation. In fact, shears or scissors must have sharp blades capable of making clean cuts that do not leave suspended filaments. A poorly executed cut exposes the plant to diseases, infections or attacks by parasites and fungi with great ease. For the same reason, all the instruments used must first be disinfected and cleaned carefully. The wound caused by the cut must be sprayed with cicatrizing product, which, in addition to closing it, acts as a protection barrier against parasites. The best time for lavender pruning is March, when vegetative growth occurs. The dried parts are generally cut three or four centimeters from the base. The pruning of lavender is however carried out with the sole purpose of allowing the plant to grow healthy and vigorous, with branches and flowers strengthened from year to year.
Because the lavender is pruned
Besides keeping the plant healthy, the goal of lavender pruning is also to guarantee the right reception of sunlight, and to promote the best possible ventilation. The removal of the dry leaf part and the trimming of the apical nodes are practiced in winter to give way to the plant to arrive at the end of the vegetative cycle without elements that can interfere with the absorption of the solar rays. Cutting branches and leaves then, gives rise to a higher and qualitatively high production of buds, reaching a perfect balance between reproductive and vegetative phase, and an aesthetic and functional harmony between roots and foliage. Although lavender is a plant that does not require excessive care, it must be said that its pruning must be practiced so as not to damage the branches and the stem. In addition to pruning, a good method for not making cuts on the plant is to bend old branches in such a way that the passage of light and air facilitates the production of new branches and spring flowering.
Lavender pruning: Growing lavender
There are different varieties of lavender, but the one that lends itself most to cultivation is undoubtedly French lavender, as, although less fragrant, it is more resistant to diseases and parasites. To grow lavender one first needs a rather large pot, as the plant does not tolerate constraints. The soil to be used is well mixed with limestone and draining sand. This last element is inserted because the plant does not tolerate stagnation of water, often due to the proliferation of fungi, and allows its correct outflow. In this regard the waterings must be done only when the soil is completely dry, so as to avoid leaf or root rot. Exposure to sunlight and especially in ventilated areas helps to recreate the hillside habitat to which lavender is accustomed. If the plant is kept in an interior it is better to add damp gravel, because lavender does not tolerate too dry environments.
