Swallow palm should change pots and add rich soil every spring. Swallow's paw grows fast. In order to keep the plant plump, it is not advisable to have too much fertilizer and water. Water 2-3 times a week during the growing period, and strictly control watering in hot and humid July-August. Poor ventilation or excessive water shortage in midsummer can also cause leaves to turn yellow and fall off, so they should be maintained in a semi-shady place. After autumn, watering gradually decreases. When cultivating outdoors, avoid heavy rain, or there will be too much water in the roots, which will easily lead to the death of rotten roots. When changing pots every year or putting houses in autumn, attention should be paid to shaping and pruning to make the plant shape more elegant. 1. Potted plants are used for planting. Before Yushu begins to grow in early spring, it should be planted or replaced with earthen pots. Potted soil should be loose, fertile and well drained. Generally, 2 parts of humus soil or peat soil, 2 parts of garden soil, 3 parts of coarse sand and 1 part of limestone gravel are selected as basin soil, or 3 parts of humus soil, garden soil, coarse sand, 1 part of mixed culture soil from plant ash are selected as basin soil. Before planting, put some broken tiles and bricks at the bottom of the basin for drainage, and cut off pests and diseases and rotten roots. Wait until the dry mouth is cut. Don't water it immediately after planting, shade it or put it in a cool place. After 4-5 days, water it 1 time, and gradually increase the light. When the root system in the basin soil is full and the drainage air permeability is poor, it is necessary to change the soil, and if possible, it is best to change the basin soil 1 time a year. 2. Light and temperature The suitable temperature for Yushu growth is 20-30℃. Spring and autumn are suitable growing periods. Shade the sun or put it in the shade when it is hot in summer to avoid direct sunlight. When the temperature exceeds 38℃, it grows slowly or enters a short dormancy. In winter, it should be placed in a greenhouse or indoor sunny place. The room temperature should be kept at 7- 10℃, and the minimum temperature should not be lower than 5℃. If it is as low as 0℃, it will freeze to death. In addition to the need for shade in hot summer, the growing season should be placed in a sunny place. 3. Water fertilization During the growth period of Yushu, water should be poured 1 time every 2-3 days, but the basin soil should not be too wet, and no water should accumulate. When the weather is hot in summer, we should strictly control watering and strengthen ventilation, otherwise it will easily cause leaves to fall. Water should be reduced in winter, and the soil in the basin should be slightly dry. Top dressing should be applied during the growth period, generally 2 ~ 3 times a month, and liquid fertilizer of decomposed pancakes should be applied. Sufficient base fertilizer should be applied before soil replacement or planting, and decomposed organic fertilizers such as chicken manure, pigeon manure, bone meal, manure and various cake fertilizers can be added to the cultivated soil as base fertilizer. In order to keep the plant plump, the fertilizer and water should not be too large to avoid excessive growth.
