Blue chrysanthemum, also known as African daisy, is a plant native to South Africa. Its flowering is very beautiful, a variety of colors, lovely and fresh flowers, loved by many flower friends. Blue chrysanthemum is a tropical plant, not cold-resistant is one of its major weaknesses, how to raise blue chrysanthemum? What are the precautions?

How to raise blue chrysanthemum

1. Temperature: given appropriate temperature according to the requirements of specific blue-eye chrysanthemum varieties, the germination temperature of most blue-eye chrysanthemum seeds is between 20-25 ℃. Too high and too low temperature will directly affect the germination rate of blue chrysanthemum seeds.

2. Humidity: the management of moisture is very important in the sowing of blue chrysanthemum seeds. Watering the bottom water with a fine sprinkler before sowing, the size of the water droplets should not impact the soil surface and keep the soil surface flat. After watering, use the fungicide to irrigate again, the commonly used agent is chlorothalonil. After sowing or covering, spray water again with a fine spray nozzle, watering thoroughly, so that the seeds are in full contact with the substrate and mulching material.

3. Light: the seeds of Chrysanthemum morifolium are beneficial to germination under light conditions. Seeds must be exposed to light after germination, otherwise the seedlings of blue chrysanthemum will grow too much. If sowing in summer, it must be shaded, otherwise the light is too strong and water evaporation is exuberant, which will affect the seed germination.

4. Cover: after sowing, cover the sowing pot with glass, plastic film or plastic film to maintain air humidity and keep warm in winter. Summer can not cover the film, cover the film can not be sealed, both sides must be ventilated. Remove the mulch in time after the blue chrysanthemum seeds germinate.

5. Transplant: when the seedlings of Chrysanthemum morifolium grow to be suitable for transplanting, they should be planted or planted in time, otherwise it is easy to cause excessive growth of seedlings and production delay.

Culture methods and matters needing attention of blue-eye chrysanthemum

1. Culture methods of blue-eye chrysanthemum

1. Growth habits

Blue chrysanthemum likes warm, sunny, fertile soil, but they can also grow tenaciously in barren, salty or dry environments. It should be noted that there are great differences in stress resistance among different varieties of blue-eye chrysanthemum. generally speaking, blue-eye chrysanthemum with strong stress resistance has spreading leaves, creeping plants, purple, pink, white and other colors, and the flower heart is mostly dark blue.

2. Mode of reproduction

There are two ways of reproduction: sowing propagation and cutting propagation. Generally, seeds are sown in autumn, winter or spring, and cutting propagation is generally in autumn and winter.

3. Maintenance

Because the flowering period of the current blue-eye chrysanthemum cultivation is relatively long, only keeping proper watering and fertilization can make the plant blossom continuously, and the withered flowers do not need to be cut off, otherwise it will not be conducive to fruiting. If you grow blue-eye chrysanthemum in a container, you must keep the soil moist. Once the soil dries up, the blue-eye chrysanthemum will go into dormancy, causing the buds to fall, and it is not easy to blossom again later. If the drought is watered again, do not water too much, the soil is too wet will lead to root rot.

4. Pest control

Because the cultivation and management of blue chrysanthemum is relatively simple, there are few diseases and insect pests. Aphids are common pests, and plants can be sprayed with 80% dichlorvos EC 800 times or 1000 times at a time.

II. Points for attention

1. it is safe to spend the summer.

Blue chrysanthemum is said to be afraid of heat, but last year both trees were safely placed on the windowsill.

2. There is no need for sunshine as long as the blue eye chrysanthemum has enough light, the windowsill without sunshine can be opened, and it can be opened on a cloudy day if there is enough scattered light.

3. The florescence is early and the number of flowers is not small.

The blue-eye chrysanthemum on the windowsill sees the flowers more than half a month earlier than the one in the open air, which may be due to the lower temperature in the open air. As for the amount of flowers, just watch the film. This is the picture from half a month ago, when there were already a lot of flowers.

When will the blue chrysanthemum blossom

Generally speaking, its flowers are in full bloom in summer and end at the end of autumn, but the temperature is higher in some areas, which can last from April in spring to November, which is equivalent to blooming for 2-3 years.

How to cut blue chrysanthemum

1. Season selection

The cutting of blue chrysanthemum branches should be carried out in spring, which is beneficial to its rooting and sprouting, but not in summer, which will greatly reduce the survival rate of cutting and affect reproduction.

2. Selection of soil matrix.

Blue chrysanthemum has strong adaptability to the environment and exuberant vitality. Therefore, the requirement for soil matrix is not high, generally speaking, sand, soil perlite and their mixed media can be used. Mixed sand is mainly to ensure the water permeability of basin soil and make it more convenient for branches to take root. Then a branch of the blue chrysanthemum can be cut from the mature and well-growing mother plant, and after simple treatment, it can be gently inserted into the basin soil.

3. Watering

When watering the cuttings, be sure to water thoroughly, and then place the plants in a ventilated and cool place to avoid the dry environment caused by water evaporation caused by direct sunlight. You can also choose to cover the plants with plastic film or plastic bags to maintain humidity. In the later stage, after the branches of blue chrysanthemum successfully grow new buds, they can be transferred to a warmer place with plenty of light. After that, you only need to keep the basin soil wet and water the blue chrysanthemum plant regularly, but pay attention to the frequency can not make the basin stagnant water.

4. Fertilization

The growth period of blue chrysanthemum is longer, which can continue from spring to late autumn, during which it will hit the top twice, and when it is planted, it can be properly applied with some base fertilizer, which is more conducive to flowering. If the light is sufficient and the humidity is suitable, the blue chrysanthemum can take up to two months from seedling to flowering.

Blue chrysanthemum is a rookie in the flower market and likes a warm, sunny growing environment. Its breeding method is not difficult, there are detailed explanations above, I hope to be able to help you. The soil must be kept moist if planted in containers.
