1、 Control temperature
Oleander will stop growing in an environment below five degrees, and it will be frostbitten below zero. The temperature in spring is unstable and the climate changes rapidly. Therefore, the maintenance temperature should be reasonably controlled, and the growth temperature should be controlled at about 15 degrees. In case of open field maintenance, the plant shall be wrapped with straw and other cold resistant materials to avoid being frostbitten by spring cold. If possible, indoor maintenance shall be continued, and open ground maintenance shall be carried out when the climate is stable p>
2、 Increase illumination
It needs more light in spring. One is to meet its light needs, but to increase the curing temperature. It is a green plant with a large demand for light. Especially in spring, it is its growth period. It needs enough light to metabolize normally and grow fast. However, the amount of light does not need to be too much. It can be guaranteed for five hours a day p>
3、 Trim properly
It grows very fast in spring, especially the main branch. Combined with the top advantage, it will inhibit the growth of side branches. In this way, the ornamental of the plant is not high, so it needs to be pruned. To trim it, generally take "Trident" trim. The specific operation is as follows: in early spring, cut off the main branch at about half a meter, and the other branches from the ground. After the incision of the main branch is full of buds, only three healthy buds are left, and all the others are removed. These three buds can be cultivated p>
