Lavender is a small shrub, from 30 cm to more than 1 m in height and diameter depending on the variety, with a naturally rounded habit. The small leaves are more or less rough to the touch, sometimes soft, narrow, green to gray, and very strongly aromatic.

The bloom is in summer, in small ears carried by long peduncles, light blue to intense purple, very scented.

How to grow a lavender plant

This Mediterranean species requires heat, apart from winter when its resistance to cold is high, and light to bloom well.

The drought exalts the production of aromatic essence. Its only known enemy is the excess of water; this is why, even if it grows on ungrateful, rocky and poor ground, the soil must be perfectly drained.

Pruning is essential to maintain clumps of dense vegetation; otherwise, the plants quickly tend to “open up”. Pruning on old wood to make up for this phenomenon is generally ineffective.

Make a light pruning, by removing 10 to 15 cm of vegetation on all the plant, at the end of the winter, and repeat the operation in summer, at the time of the harvest of flowers.

To strengthen the young plants at the time of the plantation, prune them of a third, 2 to 3 times between February and May, even if it means sacrificing the first bloom.

How to grow lavender shrubs in pots

This method of culture is easy but its success depends on the control of watering. When repotting, place a 5 cm thick drainage layer at the bottom of the pot (clay balls, for example) and use a potting soil lightened with 1/5 sand.

Keep the potting soil just moist between February and flowering and cut out every other watering in August during the summer rest period.

For the culture in pot, use preferably the dwarf lavenders.
