Climate and soil requirements
Cotton lavender prefers temperate climates with sunny exposure (it does not like the shade). It is very resistant to cold (down to -15 ° C) and drought.
It adapts to different types of soil but prefers soils that are looser, well drained and calcareous; it grows well in well-structured clay soils but dislikes soils which are too compact as they are subject to waterlogging.
Fundamentals of cultivation techniques
Cotton lavender is propagated using herbaceous cuttings and plant division.
Cuttings of 5-10 cm are taken in late summer from the apex of the stems and transplanted with roots the following spring.
Plant division is done in the spring by using small pieces of root, which have at least one node, and planting them either in seedbeds or directly in the ground.
The planting distance between the rows is 70-80 cm and within the row 50-60 cm, with a density of 2-3 plants per m2.
Fertilization is usually only done using mature manure applied during the preparation of the land for planting.
Irrigation is necessary in the summer when there have been long periods of drought; however, it is advisable to leave the soil to dry between irrigations.
Dry the leaves in a place that is sheltered from the light, dry and well ventilated.
