It has also been said that this kind of plant is not able to withstand low temperature. Friends in the North must put them in the house in winter. They require a temperature of 12-15 ℃. If the temperature is too low, it will affect their flowering time and may delay their flowering.
However, if you have enough heating in your friends' home in the north, you should also pay attention to that if the indoor temperature exceeds 24 ℃, they will also be restrained from blooming. If you want to keep them blooming, you'd better keep it at about 15 ℃. If the temperature is too high, ventilate in time, or spray water around. In this way, it can cool down properly and make up water.
This safflower doesn't have a high demand for sunlight, and it is sensitive to the reflection of light cycle, so if you want them to bloom, you can keep the sunshine for eight or nine hours every day. If you can keep it for about a month, they have no problem in growth, and they can grow flower buds. If contact with the sun for a long time, they do not like to bloom, so we must control
The most common disease of this kind of flower is leaf blight, which is also the disease that other flowers love to live. If you find a disease, you can't sit back and ignore it. First, remove the leaves that have already suffered from the disease, but don't throw them directly into the flowerpot. Then spray with appropriate amount of medicine, so as to completely eliminate the disease and prevent the disease from happening again in the near future. If you see scale insects on the stems and leaves, you need to take them off. If it is serious, you need to take off the whole leaves. You can't put them in the flowerpot either. After processing the leaves, spray them with dimethoate.
