I have some very nice Hidcote lavender I got last year. It's growing in pretty big clumps...can I divide it? I want to add it around my roses, but would rather not buy as many new plants, if I can divide some of the ones I already have :)
Trying to divide a lavender plant would be like trying to cut a tree into vertical sections, from top right down to the bottom-most roots. Neither practical nor likely to be successful.
Your best way to propagate new plants is to take cuttings. I find that heel cuttings are best and easiest with lavender.
So I take it that's a no... :)
What exactly is a heel cutting and how do I go about getting one?
Take a healthy looking shoot which is about 10cm 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 too long trim it with a sharp knife.
Dip the 'heel' in hormone rooting powder (better still, some pure honey), make a small hole in the potting mix with a pencil and place the cutting in the soil with the 'heel' lowermost. About 2-3cm 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 and keep the soil just moist.
The cutting should show some signs of growth in about 4-6 weeks.
