How to grow African chrysanthemum

African chrysanthemum flowers are larger than ordinary chrysanthemums, and the flowers are rich in color, very beautiful, and have high ornamental value. Its flower language is mysterious, mutual respect and love, perseverance, not afraid of hardship. So, how to grow gerbera?

First, how to grow gerbera?

In March-May or September-October, select full-grained seeds, soak them in warm water for 24 hours, remove them and plant them in nutritious soil. The suitable temperature for germination is 18-22 ℃ and can germinate 7-10 days after sowing. After germination, the seedlings were moved to the sunny place, and the seedlings were divided after the cotyledons were fully expanded. the seedlings could be planted when they grew 2 true leaves. The best time for colonization was May-June, and flowering could be seen 2-3 months after planting. Do a good job in daily maintenance after flowering.

Second, what are the points for attention in the daily maintenance of African chrysanthemum?

1. Soil: gerbera is sensitive to water and should use a medium with good permeability and drainage, preferably a mixture of peat and perlite. The pH value is 5.5 to 6.0 and the EC value is 0.7 to 1.0, which is beneficial to the absorption of trace elements.

2. Watering: African chrysanthemum is very sensitive to water, so it must be watered at the right time, in the morning or evening, and make the plant relatively dry at night. When the plant begins to grow roots, it must be watered from the bottom, which can be infiltrated from the bottom. Water can be watered from above the plant during high temperature, but care should be taken to prevent fungal mildew from the center of the plant.

3. Sunshine: the most suitable sunshine length in the growth process of African chrysanthemum is 11 hours to 13 hours, so artificial light can be replenished in low light, and the general requirement of artificial light is 3500 to 4000 lux per square meter.

4. Temperature: the most suitable temperature for the growth of African chrysanthemum is between 15 ℃ and 25 ℃, the highest is not higher than 30 ℃ and the lowest is not less than 13 ℃. High temperature will affect the normal flower bud differentiation, and low temperature will cause plant death.

5. Fertilization: African chrysanthemum is a fertilizer-loving perennial flower, which has a large demand for fertilizer. the ratio of nitrogen, phosphorus and potassium is 15:18:25, once every 5-6 days and once every 10 days. If the plant is semi-dormant caused by high temperature or low temperature, fertilization will be stopped.

6. Diseases and insect pests: the diseases of African chrysanthemum include leaf spot, powdery mildew and virus. Leaf spot disease was sprayed with 70% methyl topiramate wettable powder 800-1000 times or 50% carbendazim wettable powder 500 times. Powdery mildew was controlled with 1500 times of thiophanate methyl or 1000-1200 times of 1000-1200 times of 70% thiophanate methyl, once every 7 days, two to three times in a row.

7. Pruning: the withering and senescence of the lower leaves of Gerbera gerbera basal leaves should be removed in time, which is not only conducive to the germination of new leaves and flower buds, but also conducive to ventilation and enhance plant growth. In addition, if the branches and leaves of the plant are too luxuriant to cover each other, some of the leaves can be removed properly.

In warm areas, African chrysanthemum has excellent results in garden planting, flower border arrangement, lawn edge decoration and so on.
