Winter jasmine,Winter jasmine, Jasminum nudiflorum by its Latin name, ultra-luminous in midwinter with its cascade of yellow flowers, is a plant that multiplies easily. It can be layered, but propagation by cuttings of stems is a simple and effective way to multiply it, accessible to beginner gardeners.
To obtain new young plants economically and quickly to install in garden or to give as gifts, discover our advice and the technique to multiply your winter jasmine.

When to take cuttings of winter jasmine?
Winter jasmine is best propagated by cuttings late summer, in August or September from so-called semi-ripe shoots, which begin to lignify, that is to say to turn into wood. Cuttings can also be attempted in early spring, around March, from non-lignified shoots.
How to take cuttings of winter jasmine?
Equipment
- pruning shears well sharpened and disinfected with 70% alcohol
- a pencil or stick
- small terracotta pots or plastic buckets or biodegradable buckets
- a light mix of potting compost, turf and sand in equal parts or a special seed compost
- a spray bottle
Technique
- Fill pots with the potting mix : allow one small pot per cutting
- Moisten the compost slightly
- Take, using the pruning shears, cuttings from semi-ripe terminal shoots (stem still flexible but starting to turn to wood) : cut shoots 10–15 cm long.
- Remove small lower leaves
- Make a 5 cm hole in the compost using the pencil
- Insert the cuttings, pushing them two-thirds into the pot
- Firm the compost gently around the stem to keep it upright
- Moisten the substrate very lightly with the spray bottle so compost adheres to the cutting
- Place under cold frame, or in shade under cover, avoiding direct sun, and keep like this for about 4 weeks while rooting occurs. Moisten without excess with the spray bottle to keep substrate slightly damp
- Once rooting has occurred and young plant begins to produce new small leaves: after about one month, pot on individually into larger pots with a nourishing compost
- Overwinter them at a temperature between 7°C and 10°C
- You can plant your new young plants of jasmine in ground the following spring
N.B. : it is possible to make cuttings in a covered environment, which consists of surrounding the bucket or pot with transparent film or a glass cloche, airing regularly. This technique allows faster cuttings. After 3 weeks to 1 month, root system will be well developed and cutting can be potted on into a larger pot if needed.

How to layer winter jasmine?
Flexible long stems of winter jasmine lend themselves well to layering, a technique that causes new rooting from the parent plant: branches, buried but not severed, generate a new subject to leave in place or, more often, to transplant.
Winter jasmine grows to 3–4 m, giving good latitude for layering. In addition, stems bend easily.
When to layer stems of winter jasmine?
For layering Jasminum nudiflorum, proceed in spring, in April or May, when soil begins to warm and rains will favour rooting.
Equipment
- a hoe
- a grafting-type knife, disinfected
- a U-shaped peg like a tent peg or a stone, a large cobble
- a little sand to lighten substrate
- a small stake (facultative)
Technique
- Choose one of the longest stems arising from base of jasmine. Stem must be healthy and vigorous
- Prepare the layer: remove small leaves from stem over length to be buried, about 20–30 cm, then make a shallow incision to encourage root production
- Prepare soil by loosening and removing adventives and existing roots, and create a furrow 5–10 cm deep to lay the stem
- Place buried portion of stem in contact with soil, bending it so it is well covered; backfill with soil enriched with potting compost, lightened with a little sand, firming slightly
- Anchor the layer with a U-peg or, failing that, a large stone
- Raise the aerial tip of the stem and stake it if needed using a small stake (50 cm)
- Water regularly, without excess, throughout rooting period
- Stem will begin to produce roots after about one year, sometimes a little less: to check, watch for appearance of new shoots on the layer
- New young plant can then be “weaned” from parent plant by cutting stem where it enters soil
- Pot up layered plant with roots into a container while waiting for planting the following autumn.
