Soil: it is the best to use fine permeable and fertile micro acid sand. Water content: according to the principle of drought is irrigation, flood is drainage, sufficient water should be maintained before and after flower bud breeding. Fertilizer: the basic fertilizer should be used in the early stage of growth, and the additional fertilizer is mainly nitrogen fertilizer, with a small amount of phosphorus, potassium and trace element fertilizer. Lighting: about 12 hours per day.
soil
Chrysanthemum soil with good permeability, loose, fertile micro acid sand is very good. In most cases, the soil of rotten plants: garden soil: river sand = 4:4:2. If you can, disinfect the soil.
Moisture content
The water control of chrysanthemum was carried out according to the principle of "watering in case of drought, draining in case of flood". It is necessary to maintain enough water before and after the bud is gestated. While watering, we can also apply fertilizer. We also need to pay attention to the "balance of dry and wet", neither too wet nor too dry. Spray the leaves with water early and late every day.
fertilizer
In the early stage of chrysanthemum growth, the basic fertilizer should be used, and the additional fertilizer should be mainly nitrogen fertilizer, with a small amount of phosphorus, potassium and trace element fertilizer. The aim is to make the branches strong and the leaves fat. In the middle and later stages of growth, phosphorus and potassium fertilizers are mainly used. If conditions permit, flower specific fertilizers can be used. The method of combining soil and topdressing outside the root is adopted for fertilization. After fertilization, water in time. If chrysanthemum leaves are small, thin and yellow, spray 0.1% more urea solution.
Location and illumination
The culture in the basin should change with the change of the external environment. Chrysanthemums need 12 hours of light, 12 hours of darkness and 10 ℃ of night temperature for germination and growth.
trim
The chrysanthemum planted in the pot can be pruned according to the needs during the growing period. In the early stage of growth, when the growth of branches is not fixed, the processes such as coring and wiping buds are carried out to promote the growth of branches in order to better shape the flower shape.
Take care of
After the chrysanthemum grows, there will be a lot of buds, which must be removed in time, otherwise it will affect the growth of chrysanthemum. When growing small flower buds, you should choose to keep them according to your needs. If you don't want them, you should remove them as soon as possible. In the later stage, it can be handled according to the situation.
High air humidity, insufficient sunlight, poor ventilation and excessive temperature difference between day and night are the main reasons for chrysanthemum disease. Therefore, reasonable control of these diseases is the main means of disease prevention. In addition, chemical agents are also one of the main means of control.
