For the bound Rosa davurica fruit after shaping, except for the prominent damage of individual shaping branches, it can generally be lightly cut or not trimmed, as long as attention is paid to proper bending and shaping. This is because twisted branches can also stimulate the apical advantage of plants. If you want a part of the branch to expose new branches, bend it downward so that the top of the branch is lower than the bend, so that 1 ~ 3 new branches will grow at the junction soon.

Begonia likes warmth and is not cold-resistant. It grows best at around 22℃ during the day and around 65,438 05℃ at night. When it is kept at 65,438 05℃ to 20℃ in the greenhouse, it can bloom all year round. When the temperature drops to 65,438+00℃, its leaves will enter a semi-dormant state.

Matters needing attention in planting Rosa davurica

Rosa davurica don't like thick fertilizer. When planting, you can choose some hoof horns on the culture soil as the base fertilizer. In its growing period, it is generally enough to apply 1 times pancake fertilizer in 3-4 weeks. Too much fertilization, especially too much nitrogen fertilizer, will make the branches grow white and only the leaves will not bloom. Generally, fertilization can be stopped after beginning of autumn, and begonia can't use greasy fertilizer. In bud stage, the application of phosphorus and potassium fertilizer 1-2 times will lead to more flowers and bright colors.
