How does poinsettia survive the winter?

Poinsettia originated in Central America and was later introduced into China. Now that it has been widely planted in China, how does poinsettia survive the winter? Let's have a look together!

How to spend the winter with poinsettia

Poinsettia should be moved indoors immediately when the winter temperature is below 15 ℃. A protective film can be added at night and the temperature can be kept at 15: 25 ℃. Do not enter the room too early, after moving to the room, you should regularly ventilate and replenish the light, and the indoor humidity should not be too high. Do not prune after winter, even if the branches and leaves are too dense can not be pruned, a little carelessly will cut off the flower buds, affecting flowering.

2. Introduction of the method of embossing poinsettia

1. Striping propagation is a propagation method in which the branches close to the ground are pressed into the soil, and the higher branches are wrapped in moist materials such as moss, and after they take root, they are separated from the mother plant to form a new plant. The method of high pressure reproduction is generally adopted.

2. First of all, select the Lignified branches, generally choose the healthy and full branches of the first year, and peel the ring in the smooth part, the width of the ring peeling is about the same as the thickness of the branch, generally 3-4 cm; remove the phloem of the branch, the upper incision should be smooth, and then gently scrape the layer with a sharp knife. When finished, cover the incision with wet water moss or other loose and breathable materials. Generally use a 20-25 cm square polyethylene film which has good carbon dioxide and oxygen permeability, but also has a very low water vapor conduction, and can resist long-term climate change. The upper and lower ends are fastened with binding rope (especially the lower end). If the binding is not tight, the matrix is easy to dry, thus affecting the rooting of the incision.

3. Poinsettia can grow roots about two months after pressing. At this time, it can be cut off and planted in a basin to form a new plant. Poinsettia striping should be carried out from April to July.
