1、 Soil

It usually grows in sandy land, hills or valleys, so the general soil can meet the needs and has strong adaptability. But when breeding, it is best to use well drained fertile soil, which can be mixed with manure soil and peat soil

2、 Illumination

Elm likes light, and it should be provided with sufficient light time during maintenance, which should not be less than 8 hours a day. Otherwise, it will lead to the thinning of branches and leaves and the slow growth rate

3、 Watering

It cannot grow in the environment where the basin soil is too wet. It cannot be watered excessively during maintenance. It cannot be replenished at will even in the high-temperature season. A little dryness is conducive to growth. However, once the humidity is high, the root system is easy to rot, affect growth, and even lead to death

4、 Fertilization

It consumes a lot of nutrients in the peak growth season, so it should be supplemented with frequent fertilization. Apply rotten cake fertilizer once in half a month, and cooperate with nitrogen, phosphorus and potassium fertilizer. In addition, phosphorus and potassium fertilizer should also be applied once before winter to improve cold resistance

5、 Precautions

It is prone to fork branches and miscellaneous branches during growth, so it should be trimmed in time. The pruning time is usually all year round, but pay attention not to cut more in summer and rainy season, so as to avoid more nutrient loss under high temperature or high humidity, resulting in dead branches
