How to grow potted chrysanthemums

soil

The best soil for chrysanthemums is slightly acidic sandy soil that is well-permeable, loose, fertile, and easy to fertilize. In most cases the soil is made of rotten plants: garden soil: river sand = 4:4:2. If possible, you can also disinfect the soil.

Moisture

The water control of chrysanthemums is carried out according to the principle of "watering when dry and draining when flooded". Be sure to maintain adequate moisture before and after the buds are formed. You can also fertilize while watering. Another thing to pay attention to is the "balance of dryness and wetness", neither too wet nor too dry. Spray the leaves with water once every morning and evening.

fertilizer

In the early stage of chrysanthemum growth, base fertilizer should be used, and additional fertilizer should be mainly nitrogen fertilizer, with a small amount of phosphorus, potassium fertilizer and trace element fertilizer. The purpose of doing this is to make the branches strong and the leaves fat. In the middle and late stages of growth, use phosphorus and potassium fertilizers mainly. If conditions permit, you can use fertilizers specifically for flowers. Fertilization is done by combining soil and foliar fertilization. After fertilization, water should be applied in time. If the chrysanthemum leaves are small, thin and yellow, you can spray more 0.1% urea solution.

Position and lighting

The cultivation in pots needs to undergo some changes as the external environment changes. Chrysanthemums need about 12 hours of light a day, about 12 hours of darkness, and a night temperature of 10°C, which is suitable for germination and growth.

prune

Chrysanthemums planted in pots need to be pruned during their growth period as needed. In the early stages of growth, when the growth of branches is unstable, pinching and bud removal are performed to promote branch growth in order to better shape the flowers.

Care

After the chrysanthemum seedlings grow, there will be many tender shoots, which must be removed in time, otherwise it will affect the growth of the chrysanthemum. When small flower buds grow, you should choose to keep them according to your needs, and remove the unwanted ones as soon as possible. It can be handled later according to the situation.

Pests and diseases

High air humidity, insufficient sunlight, poor ventilation, and large temperature differences between day and night are all causes of chrysanthemum disease. Therefore, reasonable control of these is the main means of preventing diseases. In addition, chemical agents are also one of the main means of prevention and control.
