Propagation is one part of your overall lavender care. Here’s how you can propagate your own plant so that you can grow or share your personal crop:
How to Propagate Lavender
Decide whether you want to harvest your lavender in the spring or autumn. Harvesting softwood cuttings in the spring is less likely to cause damage to the parent plant but they are less reliable than hardwood stems when taking root. Hardwood stems can be harvested in both the spring and the fall, but are less plentiful than spring softwood.
Find the healthiest part of your plant to harvest the best cuttings. This will give you the best chance for rooting. Cuttings should be at least 3-4 inches long and should be cut just below the bump of a leaf node.
Remove the leaves from the lower 2 inches of the cutting.
Use a butter knife to gently remove some of the skin from one side of the bottom of the cutting.
Dip the tip of the cutting into a rooting hormone then gently place it into a small pot that has been filled with a mixture of half vermiculite (or perlite) and half peat moss. You should also add a little bark to aid with draining.
It typically takes about 2-4 weeks for your lavender cutting to take root (it will be a little longer if you used hardwood cuttings). While waiting, place the plants in a sunny location and ensure that the soil remains moist. You will know when they have taken root when they don’t budge when you gently tug on them.
