Propagation (read first)
Legal note: Asexually propagating a plant that is still under an active patent requires a license. Examples on the market include specific bramble cultivars (e.g., ‘Von’, ‘Nantahala’). Check status before selling clones.
Blackberries (erect, thornless)
- Tip-layering: In late summer, bend a soft cane tip to the soil and pin; roots form in a few weeks; sever and pot in fall.
- Root cuttings: Take pencil-thick root sections 3–4 in long in late winter; lay horizontally in a tray with moist media; keep warm until sprouts form.
Raspberries (primocane)
- Division/suckers: Lift and split clumps when dormant; replant immediately.
- Root cuttings also work as above.
Mulberry
- Hardwood cuttings: Late winter, 8–12 in pieces of last year’s wood; stick in well-drained mix with bottom heat if possible; maintain high humidity.
- Softwood cuttings: Early summer under mist/rooting hormone.
Passionfruit
- Semi-ripe cuttings: 4–6 in tip cuttings; remove lower leaves; rooting hormone; high humidity and warmth.
- Seed: Germinates in warmth; note that seedlings vary. For yellow types, cross-pollination is often needed later.
Pomegranate
- Hardwood cuttings: Late winter, 8–10 in cuttings from 1-year wood; stick 2–3 buds deep; bottom heat speeds rooting.
- Suckers: From established plants; replant while dormant.
