Culture method of emerald

At present, emerald is a kind of large foliage plant which is very popular with people. it is a trailing plant of Taro genus in Araceae. It has strange and changeable leaf shape, slender and dense aerial roots, whirling posture, and is very shady. It is placed indoors, which makes people feel as if they have entered the tropical rain forest. Let's take a look at the cultivation methods of emeralds.

Growth habits of emeralds

Emerald like warm, humid and semi-shady environment, although like light, but afraid of direct sunlight, shady but not cold-resistant, long-term dark growth will turn bad, poor ventilation is easy to get leaf spot disease and gray mold in high temperature and high humidity. The residual temperature of growth is 20-28 ℃, and the overwintering temperature is 5 ℃. The soil with fertile, loose and well drained slightly acidic soil is better. Will blossom, because it is not easy to blossom, easy to be mistaken for non-flowering, so the folk "rich tree" said.

Propagation methods of emeralds

The cutting propagation of emerald is easy to take root in the high temperature season, and it is generally carried out from April to August. When cutting, cut more than 3 to 4 stems for cuttings, remove the lower leaves and leave two upper molded leaves. When inserted in a basin with river sand or perlite as substrate, the leaves are often sprayed with water to keep the substrate moist. It can take root after 2-3 weeks, and the suitable temperature for rooting is 20-30 ℃. If the stem vine has grown roots can be directly on the pot, each pot planted 3 or more, and then moved to a slightly stronger light for normal management.

Culture method of emerald

1. Humidity: emeralds like a humid environment and should provide sufficient water during the growing period. Generally, it is watered once a day in spring and summer, and once every 3-5 days in autumn. Watering should grasp the principle that it is better to be wet than dry, so that the potted people often keep wet, and often spray water to the leaves to maintain a high humidity environment, which is not only conducive to plant growth, but also make the leaves fresh and bright, full of vitality. You can use a sponge to wipe off the leaf painting dust once a month to keep the leaf surface smooth.

2. Temperature: the suitable temperature for emerald growth is 20: 28 ℃, and the overwintering temperature is about 10 ℃. It should be placed in the warm and sunny place indoors in winter. The suitable temperature for rooting is 20-30 ℃.

3. Fertilization: during the growing period, emerald should apply dilute liquid fertilizer once or twice a month to promote the growth of branches and leaves. If you grow slowly or stop growing in winter, you should stop applying fertilizer.

4. Lighting: emeralds like bright light, but avoid direct sunlight. Generally, shading is needed in the growing season, but it can also tolerate the dark indoor environment, but when it is in the dark for a long time, the leaves become smaller and the leaf color becomes lighter, the internodes become longer, and the growth is weak and affect ornamental. So it is best to put it in the room where there is bright light, so that the leaves are large and colorful.

5. Change the basin: the basin can be changed once every spring, at the same time, when changing the basin in spring, the plant will be taken out of the basin and cut into several clumps for split propagation.

Matters needing attention in emerald culture

1. Emerald has a short dormancy in winter, so you should stop spraying water to the leaves and wait for the basin to dry before watering. Do not make the basin soil too wet and stagnant water, otherwise the leaves are easy to yellowing, and more water will cause rotten roots and stems to die.

2. If the weather is hot and the soil evaporation is large, water should be watered at the right time to keep the soil and water moist.

3. In order to ensure proper dryness and humidity, emerald is mainly watered by spray, except in cloudy days, which is sprayed twice a day to facilitate the germination of air roots and new buds.

4. Emerald cuttings send out new leaves for about a month, then the roots need to be fertilized with thin fertilizer once, and the subsequent fertilization is mainly foliar fertilizer, twice a month. Root application can be done 2 or 3 times a year.

5. Emerald is easy to get leaf spot disease under the condition of poor ventilation, high temperature and high humidity. The infected leaves initially had light green water-stained round spots on the leaf surface, and with the expansion of the disease spots, they developed into round or irregular brown spots, and in the later stage, there were small black spots in the middle of the disease spots. The prevention and treatment is mainly to remove the diseased leaves in time and reduce the infection source. At the same time, it can spray 500 times of chlorothalonil or 800 times of carbendazim.
