1, the best propagation time: top branch cutting or stem cutting, which can be carried out all year round. Cutting is carried out in spring and autumn.

2. The most suitable soil for growth: Arowana generally requires that the substrate is rich in humus, loose and well drained.

3, growth humidity requirements: Arowana flowers should have enough water in the growth period, the basin soil should always be moist, and try to improve the air humidity.

4. Optimum growth temperature: The suitable growth temperature of snapdragon flower is 18 ~ 22℃, and low temperature is not allowed.

5, the best growth light: Arowana is shade-resistant, suitable for scattering light and avoiding direct light.

Precautions for goldfish flower:

1, fertilization

The demand for fertilizer and water is not much for goldfish flowers, so it is enough to apply thin organic fertilizer and water every half month or so. If more phosphate fertilizer can be added before Lei gets pregnant, the flowers will bloom much more and the colors will be gorgeous. Fertilization is mainly in spring and autumn, and dilute liquid fertilizer is applied every 10~ 14 days/time. In autumn, liquid fertilizer based on nitrogen fertilizer should be applied to promote lush foliage. After spring, more phosphorus and potassium fertilizers should be applied to promote colorful. Key points of watering: Arowana flowers need more water in the vigorous growth season, and the basin soil should be kept moist in spring, summer and autumn, so as to "see dry and see wet".

prune

After flowering, all weak branches, top branches and long drooping branches should be pruned. In winter, the withered flower stems should be cut off from the base and kept dry, which is beneficial to the germination and growth of new flower branches in the next spring.

3. Reproduction

The propagation of snapdragon flowers can be carried out by top branch cutting or stem cutting. It can be done all year round, and it is best to do it indoors after flowering. Cut off the annual branches about 10 ~ 15 cm, keep 3-4 leaves, remove several pairs of leaflets at the base and insert them into the sand. Cover with glass or plastic film, control the temperature at 20℃ and maintain high air humidity, and the roots can grow in about 3 ~ 4 weeks. After two months of survival, I began to pick my heart and promote more branches, so that I could bloom more and then plant them in pots. The seedlings do not bloom in the first year, and after two or three years, they spit out red flowers between the axils of the tips of the vertical branches.
