First of all, water properly. Remember the principle that the soil will not be dry and will not be watered to the end. Water the leaves every day. In hot summer, water must be sprinkled in the morning and evening, so as to avoid no water for plants to drink. In winter, water should be sprinkled around noon. The temperature of water should be close to the temperature of soil, not cold or hot. Pay attention to no water in the basin.
Rational fertilization, which aims to see flowers, should be given sufficient fertilizer. Urea can be applied for 1-2 times when new branches are released, and phosphate fertilizer should be used as the main fertilizer after flower germination and before flowering. Before using fertilizer, the soil should be dry. It's better to make the soil soft and let the flowers absorb better. Water it again a day later.
Every 2 to 3 years, we need to change the basin to get some soil again, and remove some old roots and withered roots, so as to avoid unnecessary loss of nutrients. On the bottom of the flowerpot, a layer of carbon slag or roof tiles can be padded to facilitate ventilation and drainage, and the residue cake for pressing oil can be put as the basic fertilizer, and the soil will be evenly paved and compacted when changing the flowerpot..
Repair plastic, plastic general take the combination of qualitative and repair methods, the best is after autumn, the shape of the bad tree can be in 2 /3 or 3 /4 of the top of most of the branches cut, branches too many plants also need to cut sparse, flowers need to cut after the old and sick branches.
Then winter management, indoor winter temperature should be kept at 0-5 ℃, humidity should be kept at 50-80%. In winter, the light in the house is very important, especially in the early spring, before the sprouts recover, the sunshine is enough to remove the potted plants from the room at the end of the next spring.
