What are the precautions for propagating lavender by cuttings?
Lavender is often propagated by the pollination and sowing method, but some growers have found that long-term use of seed propagation leads to variety degradation and makes it hard to maintain the plant's superior characteristics, so more and more growers are now choosing cutting propagation to propagate lavender.
Lavender
I. Cutting selection
The upper woody shoots of the current year are best. Cutting length 8-12 cm. Cut the lower end of the cutting into a slanted surface, and it is best to leave 6-8 leaves on the upper part of the cutting, which helps the cutting retain nutrients and speeds up callusing and rooting.
II. Cutting time
Best before the soil freezes. In the Dalian area, generally from late November to early December.
III. Cutting method
Use small flat beds for cuttings, bed width 1 m, plant and row spacing 5-8 cm, insert the cuttings to a depth of one third of the cutting length, with 3-4 pairs of true leaves exposed above the ground.
IV. Field management
After planting the cuttings, cover the bed with plastic film; there is no need to press soil on the film edges, which makes it convenient to remove the film regularly later, removing it every 5-6 d for ventilation and air exchange. Watering: after autumn cutting, irrigate once so the cuttings and soil are firmly in contact. After that, irrigate about every 15-20 d. The following spring, as temperatures rise and evaporation increases, begin irrigation management to avoid drought; this period is the key time for the plants to callus and root. When watering during the seedling stage, do not flood the seedlings, do not let water accumulate, and do not let the leaves stick to mud, otherwise the seedlings will suffocate and die. Cultivate and loosen the soil: in early spring the temperature is low and soil temperature rises slowly, so loosen the soil and weed in time to raise the soil temperature, which helps the cuttings callus and root and cultivates strong seedlings. When loosening the soil, avoid injuring the seedlings, work from shallow to deep, and do not loosen the cuttings, which would affect survival.
In April of the following year, temperatures rise and the seedlings grow faster, so water can be controlled appropriately to avoid excessive leggy growth. After that, harden the seedlings gradually, and by mid-April they can be transplanted and planted out in the open field.

Cutting propagation time for fernleaf lavender
Cutting propagation of fernleaf lavender is suitable in spring, autumn and winter.
Selection of cuttings for fernleaf lavender
Choose healthy, strong branches, which can be cut from the third stem node above the terminal bud.
Propagation method for fernleaf lavender by cuttings
If the cutting has flower spikes, cut off the flower spikes first, leave the lowest pair of leaves, moisten the medium and insert the cutting. After the cutting roots, it can be potted directly for planting or planted in a flower bed.
How to propagate lavender by cuttings, the cutting propagation method for lavender
Lavender is a flower with particularly beautiful blooms. Lavender can be grown not only as an ornamental plant but also used as a medicinal material. Lavender has fairly good growth habits and is also relatively easy to propagate. Lavender can be propagated by sowing and also by cuttings. Today let us learn how to propagate lavender by cuttings, the cutting propagation method for lavender.

That is all for how to propagate lavender by cuttings and the cutting propagation method for lavender. Lavender is heat-tolerant, drought-tolerant and especially cold-tolerant, making it a very good cultivated flower. Lavender also likes sunlight and needs sufficient light to grow well. Lavender fears dampness, so avoid water accumulating in the potting soil and avoid causing root rot.
