Key points of cultivation of fortune tree:

Rich trees like high temperature and high humidity climate, with poor cold tolerance and easy to die below 6℃.

Nostoc flagelliforme is a strong positive plant, but it has strong shade tolerance and can be watched continuously for 2-4 weeks in a place with weak indoor light. Then put it in a place with strong light.

There should be enough water in the high temperature growth period; But it is drought-tolerant, and it will not suffer if it is not watered for several days. But don't drink water in the basin. Reduce watering in winter. Watering should follow the principle of intermittent dry and intermittent wet. In spring and autumn, the watering density should be controlled according to the weather, such as sunny rain, wet and dry. Generally, water 1 time a day. When the temperature exceeds 35℃, water it at least twice a day and fertilize it twice a month during the growing season. For new leaves, pay attention to spraying water and maintain a high environmental humidity. Shading should be carried out from June to September, and the light transmittance should be kept at 60%-70% or placed in a place with strong scattered light. After entering the room in winter, the temperature should not be lower than 5℃, and it is better to keep it at about 10℃, water it 1 time for 5-7 days, and ensure sufficient illumination. In addition, in the growing season, if there is poor ventilation, it is prone to the harm of red spiders and scale insects, so pay attention to observation. Pests should be caught or sprayed in time, and pots can be changed as needed in spring, preferably once every 1-2 years.

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. In addition, in the growth period of Nostoc flagelliforme (May-September), decomposed liquid fertilizer or mixed flower fertilizer can be applied once every 65,438+05 days to promote deep roots and lush foliage.

Common fertilizers are: bean cake (which can only be fertilized after decomposition), bone meal, plant ash, etc. Some wastes in daily life can be used as flower fertilizer.

1. Water from rice washing, leftover tea, bottle brushing and soymilk machine can all be used as topdressing to water flowers. The nitrogen, phosphorus and potassium contained in it can promote the development of flower roots, the differentiation of branches and buds and the robustness of plants. If the collected Chinese medicine residues can be mixed into the surface of the basin soil and the basin soil is kept moist, the basin soil can be gradually improved; If the residue of Chinese medicine is soaked and retted to make mature fertilizer water, it is the first-class topdressing of flowers. Second, bury human hair, nails, hoof horns of livestock, pig hair, chicken and duck hair, etc. The soil near the basin is an excellent phosphate fertilizer, and the fertilizer effect lasts for about two years. Eggshells, miscellaneous bones and fishbone scales can not only be used as basic fertilizers for potted flowers,

Three, peel, melon peel, and old leaves and rotten leaves in leafy vegetables, after accumulation, mixed with two-thirds of the sand, and put them in containers such as cans, barrels and cans. It is tightly sealed and turned into humus soil, which is the best potted flower soil.

There are some flower fertilizers on the market, such as Big Fat King, which are less than the prescribed dosage. Fertilize plants with less than more.
