Improper fertilization leads to defoliation, so it is necessary to remove the flowerpot from the happy tree, trim off the rotten roots, dry it and replant it in the soil, and the happy tree will gradually return to normal growth. Too much watering causes the leaves of the happiness tree to fall off, so it is necessary to change pots and soil in time. If the temperature is too high and leaves fall off, move them to the shade for maintenance in time to cool the plants.
In order to ensure the beautiful tree shape and sparse branches and leaves, reasonable pruning should be carried out. The 1 pruning should be carried out before spring germination, and some old leaves and over-dense branches and leaves should be pruned. If there are many lateral branches in the happiness tree, the core can be removed to make the plant round and beautiful.
cultivation techniques
1, temperature
Bean trees like warm and hot environment, and the suitable temperature for growth is 20-30℃. In midsummer, when the ambient temperature reaches above 30℃, it is necessary to build a shed for shade, spray water on the leaves, or move to a cool, ventilated and cool place for the summer. When the ambient temperature drops to 10℃ in late autumn, it should be moved into the shed in time.
2. Lighting equipment
Bean trees like light, but also slightly tolerant to shade, and can be used in full sunshine and semi-shade environment. Its seedlings are more shade-tolerant, so it is necessary to build a shed to shade them in summer. When displayed indoors, potted plants should be placed in front of well-lit windows.
Step 3: Moisture
Bean trees need relatively humid soil and display environment. Pay more attention to water supply in the hot and dry season after summer. In order to prevent potted plants from growing too high, watering can be properly controlled to keep the pot soil moist when new buds sprout in spring. Potted plants placed indoors should be sprayed with water 2-3 times a day in high temperature season.
4. Land
Potted soil should be loose and fertile, with good drainage and ventilation, and rich in organic matter. It is usually made up of 5 parts of garden soil, 3 parts of humus soil, 1 part of decomposed organic fertilizer and 1 part of river sand. In the growing season, loosen the soil twice a month to ensure that the roots are always in a good state of permeability. Small and medium-sized plants can turn over pots at the beginning of April every year to meet the requirements of their annual growth on soil fertility.
