First of all, light
Strengthen plant light. Elm likes sunny environment. If the sunshine is insufficient, it will make its branches white and long, its leaves ugly, and it is easy to breed various pests and diseases.
Second, water.
Keep the soil in the elm basin moist, but don't accumulate water. Elms like to live in wet places, but they are also afraid of water stains. So water it once in the morning and once in the evening in summer. If water accumulates, it needs to be treated as soon as possible.
Third, fertilization.
Elms should be properly fertilized. Fertilization should be liquid fertilizer, or peanut cake should be broken into thumb size and buried in the soil, or some compound flower fertilizer can be used. Fertilization should be applied once in early spring and early autumn, not more.
Fourth, pruning
Keep elm trees in good condition and prune them frequently. Elm has a strong growth ability. If the buds are not pruned, the pile landscape will lose its ornamental value. Trimming and shaping can be done in autumn. Cut off useless branches and diseased branches first, and then trim them in a formed or formed posture.
Verb (abbreviation for verb) pest
Aphids and scale insects are the most common pests in elm trees. When these two pests occur, omethoate can be sprayed with 1000 times of liquid medicine. Elm can be used as a bonsai for viewing and can also be used to decorate the courtyard. However, the big stump should be transplanted with foreign soil before the leaves germinate in winter and spring. After planting, wrap the stalks with straw mixed with yellow mud water and water them frequently to ensure the soil and stalks are moist.
