HOW TO PROPAGATE LAVENDER
There are three methods of propagation. By
cuttings, seed and layering.
Propagate Lavender By Cuttings
|
|
Cuttings are the easiest method and the chances of success are high. In
addition, you are guaranteed that the new plant will be exactly the same
as the parent plant.
The best method is to take a heel cutting in spring. This can also be
done in autumn but the cutting will take longer to root. First fill the
a pot(s) by filling with a sandy compost. Water it so the soil is damp
but not dripping.

To take a heel cutting, identify a healthy looking shoot which is
about 10cm (4in) long and pull it down and away from the main stem. You
will end up with a shoot which has a "heel" of the main stem at its
base. If the heel is a bit to long then trim it up a bit with a sharp
knife.
Dip the "heel" in hormone rooting powder or solution, make a small
hole in the compost with a pencil and place the cutting in the soil with
the "heel" lowermost. About 3cm (1in) of the cutting should be below the
soil. Gently firm the soil down around the cutting. Keep the cuttings in
a light airy position out of direct sunlight keeping the soil just
moist.
The lavender should show some signs of growth around 4 to 6 weeks
later. If it outgrows the pot, pot into a larger one. The rooted cutting
can be planted in its final position in early autumn.
Propagate Lavender By Seed
Lavender will not grow true to the parent type when grown from seed. For
this reason we do not recommend this method of propagation.
In autumn when the seeds are ripe (they should be dry and black),
collect them and place them in a compost filled pot (see cuttings above)
and a very thin layer of compost scattered over them. Place them in a
well-ventilated, warm and dark position. The seeds will take about six
weeks to emerge. Then treat them as cuttings and plant in their final
positions the next autumn.
Propagate Lavender By Layering
In early autumn select a long stem and gently bend it down to ground
level. Peg it onto ground with a hoop shaped piece of wire and cover
with 3cm (1in) of soil. The layer will produce growth the next spring.
When this has happened, sever the stem from the parent plant and pot
into soil as described for heel cuttings.
Transplant into its final position in early autumn. The plant will be
an exact replica of the parent and the chances of success are high.
