Wintersweet propagation methods include seed sowing, grafting, division, cuttings, and layering. Grafting is the most widely used, because it can produce superior varieties.

1. Cleft grafting. Cleft grafting is commonly used for wintersweet. For cleft grafting, use dog-tooth wintersweet or wintersweet seedlings as rootstock. Select a sturdy two-year-old wintersweet branch, take the middle section and cut it into segments 6-8 cm long as scions. The key to a high survival rate with cleft grafting lies in choosing the right grafting time. Cleft grafting is most likely to succeed when the wintersweet leaf buds swell to the size of a wheat grain, and this suitable window lasts only about 1 week. If the leaf buds have already sprouted too much, the survival rate of cleft grafting is very low. The cleft grafting method is the same as general woody plant cleft grafting. When the grafted seedling grows to about 50 cm, pinch off the tip to encourage more side branches; after 2-3 years of cultivation it will bloom.

2. Side grafting. The best time for side grafting is from mid-June to mid-July. If done too early, it affects the tender scion's survival; if done too late, it may survive but is not conducive to overwintering. For rootstock, choose vigorous 1-2 year old wintersweet or dog-tooth wintersweet seedlings; for scions, choose tender vigorous current-year branches of superior wintersweet varieties. For side grafting, first make a slanted cut at the base of the rootstock about 5 cm above the ground, reaching deep into the xylem, with a cut about 2 cm long. Then cut the scion on both the front and back sides, forming a horse-ear shape, leaving one bud segment per scion, and cut off 2/3 of the top two leaves. Insert it into the rootstock cut, align the cambium, and tie it moderately with plastic strips from bottom to top. A pair of opposite buds is left exposed at the top. Finally, cover it with a plastic bag to help retain moisture. About 1 month after side grafting, the scion buds begin to swell, and at this point the plastic bag can be removed. To encourage scion sprouting, cut off the rootstock 2-3 cm above the graft union; when the buds grow 2-4 pairs of leaves, remove all the binding material, and promptly remove sprouts on the rootstock to promote healthy scion growth.

How to grow wintersweet: wintersweet care methods and tips1. Wintersweet care methods and tips: pay attention to wintersweet water and fertilizer management

Wintersweet is a flower that is particularly drought-tolerant. When grown in pots, wintersweet does not need much water. In spring and autumn, it does not need much water; if the water in the potting soil has not dried out, there is no need to water. In summer, when the weather is hot and evaporation is high, it needs to be watered once in the morning and once in the evening. Wintersweet is a flower that particularly likes fertilizer, but the fertilizer should not be too concentrated. Apply fertilizer once a month from April to November, and apply one extra time in late June, which is good for flower development. At this time, wintersweet is about to undergo flower bud differentiation.

2. Wintersweet care methods and tips require shaping and pruning

Wintersweet needs pruning. At the seedling stage, select thick branches and trunks to keep, and cut off the weak small branches, so that the strong branches and trunks can be retained. After the flowering period each year, pruning is also necessary. Only after cutting these branches can strong new shoots grow. At the same time, pay attention to pruning the tree shape of wintersweet, since wintersweet is generally a potted ornamental plant.

3. Wintersweet care methods and tips for pest and disease management

Although wintersweet does not have many pests and diseases, if pests or diseases occur, you can cut off these diseased branches after wintersweet enters dormancy.
