Rich trees like high temperature and high humidity climate, with poor cold tolerance and frost-free seedlings. Adult trees can tolerate light frost and long-term low temperature of 5-6℃. They can overwinter in the open air in the south, and they must move into greenhouses in the north to prevent cold in winter. Like fertile and loose sandy loam, it has air permeability and water retention; Love acidic soil, avoid alkaline soil or cohesive soil; More resistant to water and humidity, slightly resistant to drought.
Lighting requirements
Rich trees like high temperature, high humidity and sunshine, and cannot be shaded for a long time. Therefore, when maintaining and managing, it should be placed in a sunny place indoors. When placed, the leaves must face the sun. Otherwise, due to the phototaxis of leaves, the whole branches and leaves will be distorted. In addition, spraying water on the leaves with a watering can every 3 to 5 days is not only beneficial to photosynthesis, but also makes the branches and leaves more beautiful.
Pay attention to watering
Watering is an important link in the process of conservation management. Less water, stagnant branches and leaves; Too much water may lead to the death of rotten roots; If the amount of water is moderate, the branches and leaves will become bigger. The first principle of watering is wet rather than dry, followed by "two more and two less", that is, water more in summer and hot season and less in winter; Large and medium-sized plants with vigorous growth should be watered more, and small plants newly planted in pots should be watered less.
Excessive watering can easily cause plants to rot, leading to drooping leaves, loss of luster and even falling off. At this time, it should be moved to the shade immediately, and the watering amount should be reduced to a minimum. As long as the pot soil is not dry, spray water on the leaves several times a day with a watering can, stop fertilizing and watering, and it will gradually recover in about 15 to 20 days.
rational application of fertilizer
Rich trees are flowers and trees that like fertilizer, and the demand for fertilizer is greater than that of other ordinary flowers and trees. When changing pots every year, the proportion of fertile soil can account for 1/3 or even more. Rich soil has a wide range of sources, and it can be collected from deciduous humus soil of broad-leaved trees, mixed with a little pastoral soil, miscellaneous bone powder and bean cake residue. This fertile soil is efficient and easy to obtain, but it should be fully decomposed to avoid "burning" the leaves yellow.
