Culture method of red leaf evergreen

Pot soil: red leaf evergreen can be made of rotten leaf soil, garden soil and river sand mixed with a small amount of mature base fertilizer according to a certain proportion, and the basin can be changed once a year in spring. Temperature: the best growth temperature is 15-18 ℃, not less than 5 ℃. Lighting: like semi-overcast environment, should not be direct, pay attention to shade. Plastic surgery: timely pruning the lower yellow leaves, residual leaves and some old leaves of the plant. Water and fertilizer: apply liquid fertilizer every 10-15 days, water 1-2 times a day in summer and less in winter.

I. the culture method of red leaf evergreen

1. Basin soil

The potted red leaf evergreen can be cultivated with 2 parts of rotten leaf soil, 1 part of garden soil and 1 part of river sand mixed with a small amount of mature base fertilizer. In the growing period, must be more watering to ensure that the basin soil wet, rather wet than dry, but also foliar spray water, autumn need to control moisture, between dry and wet, keep the basin dry in winter, and change the basin once a year in spring.

2. Temperature

The temperature suitable for the growth of red leaf evergreen is 15-18 ℃. When it comes to dormancy in winter, it should be placed in a sunny place. The temperature should be kept above 10 ℃, and the lowest temperature should not be lower than 5 ℃. In the Yangtze River valley, you can spend the winter in the open field, and the leaves will be damaged by freezing, but new leaves can sprout again in the coming year.

3. Lighting

Red leaf evergreen likes to grow in a semi-overcast environment and should be protected from direct sunlight in summer. Greenhouse farming, except for winter shade should be more than 60%, winter shade 40%, because the light is too strong easy to burn, the light is too weak is not conducive to blossom and bear fruit.

4. Plastic surgery

According to the growth of the plant, pruning the yellow leaves, residual leaves and some old leaves in the lower part of the plant in time is beneficial to maintain the good shape of the plant and improve the ornamental value. Such as family farming, you can use a soft cloth dipped in beer to wipe the leaves, which can not only remove the dust, but also increase the nutrition to the leaves, making them cleaner and bright green.

5. Water and fertilizer

During the growing period, liquid fertilizer should be applied every 10-15 days. In summer, it is necessary to strengthen ventilation, prevent heat and cool down, ensure sufficient water, keep the basin soil moist, water 1-2 times a day in summer, and a small amount in winter without fertilization.

II. Methods of reproduction

1. Sowing method: generally, sub-sowing can be carried out in March-April, sowed in flowerpots of good culture soil, and then watered to keep the soil moist and placed in shade. Under the temperature of 25-30 ℃, it will germinate in about 25 days.

2. Split method: because of its strong sprouting power, the new sprouting and lateral roots of the rhizome can be removed together with a knife in spring and autumn, then apply plant ash on the wound, pour a small amount of water in the transplanting basin, and place it in the shade. After 1-2 days, it can be watered. You can also pour the whole plant out of the basin, divide it into several parts with a knife according to the size of the plant, and apply plant ash after the wound is dried, the pot method is the same as before.

3. Cutting method: cut off the small plants from the base of the plant in April-May in spring, wait for the wound to dry, apply plant ash and insert it into the plain sand soil, be sure to shade and moisturize, it will take root in about 30 days, and you can put it on the basin.

Matters needing attention in aquaculture

1. Because it is a fleshy root plant, it should not be overwatered. Stagnant water can easily lead to waterlogging and serious root rot.

2. If the leaf tip is yellow and scorched in winter, or even the whole plant withered, the reason is that the root can not absorb water, which affects its growth.

3. Indoor culture should keep warm, moist and semi-shady environment, and should be placed in the shade during the summer growing season to prevent direct light, otherwise it will easily lead to dry tip and scorched edge of the leaves, thus affecting the ornamental effect.
