A young lavender plant will be made up of entirely green sections. It’s important to have old and new growth so that stable roots are able to grow out of the younger plant.
Having 3-5 leaf nodes is important so that the cutting is mature enough to grow strong roots.
Avoid using scissors as they can damage the plant and partially close up the stem making it hard for the roots to grow properly.
Remove the bottom section of leaves easily by taking the stem between your fingers and pulling down on it gently. Removing the bottom leaves lets you put this section of the stem into the soil.
The lavender buds will start off green and turn purple as they continue to grow.
Purchase a rooting hormone from your local gardening center, big box store, or online.
Try using terracotta pots instead of plastic ones as they breathe better. Lavender cuttings do well in soil that’s airy. Make sure the cuttings will have at least 2 in (5. 1 cm) of space around them in the pot.
For example, if your cutting is only 3–4 in (7. 6–10. 2 cm) tall, your hole only needs to be about 1 in (2. 5 cm) deep so that it’s roughly 1/4 the length of the stem. Making the hole is important so that the rooting hormone doesn’t rub off when you’re sticking the cutting into the soil.
You can place several different cuttings in one large pot, but make sure they’re not touching.
Check the soil every couple of days to be sure the soil is still moist but not soaked through.
Lavender cuttings do well in humid environments as opposed to dry ones. Consider putting a clear plastic bag over the pot to create a greenhouse effect, if desired.
How fast the cuttings take root depends on the temperature and humidity of their environment.
If you planted several cuttings, move each of them into their own pot. Giving each cutting their own pot will allow their roots to flourish and grow.
If you want your cutting to continue growing faster, snip off any flower buds that pop up. Otherwise, let the lavender flowers grow.
