Emerald Introduction Emerald, native to the tropical region of South Africa, is known as the "Emerald", commonly known as "Emerald". It is a kind of foliage plant. It is not uncommon in the place of origin, but it is difficult to flower in the north, just like iron tree blossom. Generally very rare. The emerald is about two months old, and the flowering period is only 12 hours. It is extremely precious, and the floral fragrance has a strong bactericidal effect. Emerald eucalyptus is a vine species with thick stems and gas roots on the nodes; leaves long heart-shaped, 25-35 cm long, 12-18 cm wide, endlessly pointed, base deep heart-shaped, green, whole, Shiny.

The breeding method of emerald 1. The soil is mixed with humus soil and garden soil, and mixed with a small amount of river sand.
2. Management In the daily cultivation management, it is necessary to support the column wood or bamboo, plastic tube, and wrap the outer circumference of the column with brown skin or shading net, plant 3-5 seedlings beside the column wood, let the small seedlings attach to it. The column grows upwards. After planting, place it in the scattered light for conservation, or hang it. Avoid direct sunlight, otherwise it will burn the leaves or cause the shadows to die, which will hinder growth and beauty.
3, humidity gems like wet environment, the supply should be supplied with sufficient water. Watering is usually done once a day in spring and summer, and once in 3-5 days in autumn. Watering should master the principle of dampness and dampness, so that the pots are always kept moist, and often spray water to the foliage to maintain a high humidity environment, which is conducive to plant growth, and will make the leaves fresh and bright, full of vitality. The sponge can also be used to wipe the leaves once a month to keep the leaves smooth. Emerald has a short period of dormancy in winter, should stop spraying water to the foliage, and wait for the pots to dry and then water, do not make the basin soil too wet and accumulated water, otherwise the leaves are easy to yellow, water will also cause rotten roots Rotten stems to death.
4. The temperature growth temperature is 20-28 °C. The wintering temperature is safer at around 10 °C, and the winter should be placed in the warm sunny place of the room. The suitable temperature for rooting is 20-30 °C.
5, fertilization of emerald in the growing season should be applied 1-2 times a thin liquid fertilizer to promote the growth of foliage. If the growth is slow or stops growing in winter, fertilization should be stopped.
Breeding methods and precautions for emeralds 6. Light green gems like bright light, but avoid direct sunlight. Generally, it needs to be shaded during the growing season, but it can also endure the dark indoor environment. However, when it is in the dark for a long time, the leaves become smaller and the leaves become lighter, the internodes become longer, and the growth is weak and affects the viewing. Therefore, it is best to place it indoors in bright light, so that the leaves are large and colorful.
7, cutting emerald can be used for cutting and ramets, easy to root in the hot season. Generally, the cuttings are carried out between April and August, and when the cuttings are cut, 3 to 4 knots of stems are cut into strips, the lower leaves are removed, and two upper leaves are left. Inserted in a basin made of river sand or perlite, the water is often sprayed on the leaf surface to keep the substrate moist. The root can be rooted after 2-3 weeks, and the suitable temperature for rooting is 20-30 °C. If the stems have long roots, they can be directly placed on the pots, and 3 or more plants per pot. Move to a slightly stronger light for normal management. If you use the top cuttings, insert 2-3 per pot, and live in a short-term inner-machi to fill the basin, the viewing effect is better. The plant grows fast, and it is full of hoops in 2-3 years.
8. Change the basin every spring. You can change the pot once a year. At the same time, when the spring is combined with changing the pot, the plant will be taken out from the pot and cut into several small clumps for sub-plant breeding.
Precautions for emerald farming:
1 In the case of soil planting, yellow leaves occur due to rotten roots. Soilless culture can also cause diseases due to soil contamination, causing the plants to produce dead roots and causing yellow leaves.
2 climatic conditions are not suitable. If the room temperature in winter is below 10 °C, rotten roots and yellow leaves will be produced at low temperatures for a long time.
3 air humidity is not suitable. If the flower pot is close to the heating, stove or air conditioner, the air will be too dry and the leaves will be yellow or even dead.
4 insufficient light. Although ruby ​​emeralds do not like glare, leaf yellow occurs when placed in dark places for a long time.
5 Long-term poor ventilation, environmental hypoxia caused by yellow leaves.
6 Insufficient insulation in winter, the plants are blown by cold wind, or the summer heatstroke is improperly cooled, and the high temperature time is too long, which will cause the leaves to be acutely dehydrated and dry and yellow.
7 improper fertilization. One is the soilless potted plant, the concentration of the nutrient solution is too high to cause the yellow leaf; the second is that the pH value of the nutrient solution is too high, and the yellow leaf is also seriously deficient in iron. Therefore, after the yellow leaves occur, the cause should be analyzed in detail, and corresponding measures should be taken.
