How to cultivate African Chrysanthemum and its Culture methods and points for attention

Hearing the name, African chrysanthemum knows that the origin of this plant is not in China, it is a kind of flower variety introduced and cultivated from abroad in our country. African chrysanthemum has a high ornamental value, so it attracts a lot of people to raise it. But most people will have some problems in the process of breeding because of improper technology, so how to raise it to make it grow well?

How to raise Gerbera

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. Sunlight: 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.

3. 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.

Culture methods and matters needing attention of African Chrysanthemum

1. Culture methods:

1. 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.

2. 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.

3. 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.

2. points for attention:

Fertilizer should not be allowed to spread to the heart of the chrysanthemum, otherwise the growing point of the heart is easy to rot and die, and the fertilizer can not be spilled on the leaves, otherwise the leaves will be burned out.

The solution to the rotting Root of African Chrysanthemum

1. Reasonable watering. Rational watering is the fundamental measure to prevent the rotting roots of African chrysanthemum. When raising African chrysanthemum, you need to pay attention to the dry and humidity of the soil and keep it moist properly, but not too wet. In the dormant period to reduce watering, the soil is not dry, do not water. Pay attention to timely drainage in the rainy season.

2. Choose the right soil. To cultivate African chrysanthemum, it is necessary to choose soil with good drainage. The soil should be loose and breathable, and the rotten leaf soil rich in organic matter or slightly acidic sandy soil is the best.

3. Timely drainage. In the rainy season, rainproof measures to prevent rain and timely drainage are preventive measures to reduce soil water accumulation, not carelessly.

4. prevention and control of diseases and insect pests. To control diseases and insect pests and reduce the chance of gerbera disease can reduce the frequency of root rot to some extent.

Insect pests of Gerbera jamesonii and its control

1. Whitefly. Bemisia Tabaci is a common pest of African chrysanthemum. It is found that pests need to clean up the growth environment of African chrysanthemum in time, select chemicals and use them correctly to avoid the lack of insecticide repellent caused by drug resistance.

2. Thrips. Thrips are also a common pest of African chrysanthemum, and cooking pesticides is a good way to find thrips. Dichlorvos or imidacloprid can be sprayed.

3. Cabbage worm. The harm of Pieris rapae is mainly divided into larvae and advanced instar larvae, which need to be sprayed and sprayed several times in time to prevent the harm from further spreading.

African chrysanthemum in breeding must pay attention to the proportion of soil, and then reasonable light, timely fertilizer and water are the inevitable factors to ensure its growth. African chrysanthemum in the breeding process may also appear the phenomenon of rotten roots, generally caused by water, insect pests and other reasons, it is necessary to find out the cause and start from the root causes.
