Question

I tried and I didnt succeed. I use IBA pottassium salt . Most of cuttings are live but no cutting has rooted yet.

Answer 1

Many plants are slow to root from cuttings. This is a plant that you could also try from seed according to sources on web. Good luck.

Propagation

Cuttings of semi-ripe terminal shoots, 5 - 8cm long, August in a frame. Protect from frost. Forms roots in the spring[78].

Cuttings of mature terminal shoots, 5 - 10cm long, September/October in a cold frame. Takes 12 months[78].

Cuttings of soft to semi-ripe wood, early summer in a frame. Slow but sure.

Seed - stratification will probably improve germination so sow fresh seed in the autumn in a cold frame if possible[80]. Sow stored seed as early in the year as possible in a cold frame[78]. A position in light shade is probably best[78]. Seed should not be allowed to dry out and should be stored in a cool place[80]. Prick out the seedlings into individual pots when they are large enough to handle and grow them on in the greenhouse or cold frame for their first winter. They can be planted out into their permanent positions in early summer of the following year, or be placed in an outdoor nursery bed for a year or so to increase in size. They might need protection from spring frosts.

Answer 2

Take cuttings of new growth about 6 inches long. Strip the leaves (needles) from the bottom half of the cutting. Dip in Rootone and place in moist potting soil. Put pot inside a zip-type storage bag, seal, and place on a sunny (south) window. When you see new growth on the cutting you will have roots.

good luck
