1、 Breeding method

1. Soil: soft soil is the best choice for the better growth of safflower stars. Its roots need to breathe oxygen through soft soil, and alkaline soil is more suitable for its growth. Therefore, it is suggested that flower friends should choose lime or sandy soil when breeding

2. Watering: it is a plant with a large demand for water, especially when breeding flower buds. Enough water can help its flowers bloom brightly and greatly prolong its flowering period. Note: there shall be no ponding

3. Temperature: the temperature of about 25 ℃ can make it grow better. The mild ambient temperature can make it in a vigorous growth state, promote it to absorb the nutrients in the soil, and the flowering period will become longer. Too high temperature in summer will make it in a depressed state, while too low temperature in winter will make it go into dormancy

4. Fertilizer: for better plant growth and longer flowering period, in addition to the appropriate temperature, appropriate fertilization is also very important. Apply nitrogen fertilizer before it blooms. The effect will be better when nitrogen, phosphorus and potassium are used together at the flowering stage. It is best to apply fertilizer once every half a month

2、 Pest control

Compared with insect pests, the disease of safflower star is relatively few, which can also be said to be basically absent, because it grows faster and takes a short time to form. Most of the pests are aphids and red spiders, and the symptoms of pests are similar. After the pests are found, the diseased branches can be removed. Spraying with 1000 times of Omethoate emulsion with a concentration of 40% can also be used for control
