Emerald tree likes loose and fertile soil with good drainage and rich humus. The soil configuration of the emerald tree purchased directly from the outside is generally garden soil + rotten leaf soil + rotten organic fertilizer + river sand, mixed according to 5:3:1:1. But now most of them will add perlite or vermiculite to the soil to avoid soil hardening.
Emerald tree likes a humid environment. During its growth, it not only keeps high environmental humidity, but also needs to maintain certain soil humidity. However, in spring, during the process of bud germination and new shoot growth, it is necessary to properly control the water content to avoid excessive growth of branches.
In spring, water should be poured once every 2-3 days. When the temperature is high in summer and autumn, water should be poured once every 1-2 days. In winter, water should be controlled properly. Water should be poured once every 7-8 days. When watering, pay attention to the weather conditions, choose to water in sunny days, not in cloudy days. In addition, in the dry and hot season, spray water to the plant every day to keep a certain humidity, so as to prevent the leaves from evaporating and falling off.
Happiness tree likes warm and humid environment, and its growth temperature is between 20 and 30 degrees. When the environment is more than 30 degrees, it is necessary to properly cover the temperature, increase the environment and spray water on the leaves, or move it to a cool and ventilated place. When the temperature drops below 10 degrees, move the emerald tree to the shed. During the winter, the indoor temperature shall not be lower than 8 degrees, and the minimum temperature shall not be lower than 5 degrees, so as to avoid cold damage or falling leaves.
Emerald tree like humid environment, air humidity is generally kept at 70-80%, the humidity of well ventilated toilet is very good! Home indoor placement, can often use slightly warm water spray plants, to keep the leaves beautiful, but also to increase air humidity.
Emerald tree likes light and bears shade a little. It can grow in full or half shade environment.
Happiness tree has different performance in different growth periods. It can grow well only when it is shade resistant in seedling period; it is better to put adult plants in front of the window with sufficient indoor light, sometimes full light, sometimes scattered light. If emerald tree grows in dark environment for a long time, it is easy to cause falling leaves.
In April of each year, the temperature rises, the emerald tree is moved to outdoor breeding, combined with turning basin, and certain compound fertilizer is added to the soil; in the growth season, the rotten liquid fertilizer is killed once a month, and after the Mid Autumn Festival, the phosphorus and potassium fertilizer is applied, so as to enhance the cold resistance of the plant and ensure its safe wintering.
It should be noted that the temperature is higher than 32 ℃ in summer and lower than 12 ℃ in winter, and fertilization should be stopped. Because at this temperature, the growth of emerald tree is slow, and the absorption capacity of fertilizer is poor. The fertilizer stays in the basin soil for a long time, which is easy to cause fertilizer damage.
1. Avoid frostbite. summer and winter are the most difficult seasons for emerald tree, either hot or cold, the heat is good, but once cold, the plant is easily frostbitten. Therefore, after winter, the happiness degree shall be moved to indoor maintenance in time, and the temperature shall be kept above 10 ℃. If the heat preservation measures are improper and the temperature is below 5 ℃ for a long time, it is likely to cause cold damage and defoliation.
2. Diseases and insect pests. emerald tree is afraid of freezing in winter and being stuffy in summer. The sultry environment is easy to cause various diseases and insect pests. Prevention should be done in time. Once insects are found on the leaves, spray chemicals immediately and strengthen ventilation. In case of yellow leaves falling off, clean the yellow leaves in time and spray bactericide.
