1. Cultivation soilWhen cultivating cosmos bonsai, you must choose soil suitable for the growth of the plant, otherwise its growth will deteriorate. It is best to use soil with good air permeability and drainage, which helps the plant roots breathe and grow more healthily. 2. LightingIt prefers sunlight, so it needs more sunlight during the growing period to grow better. When there is sufficient light, it will not only grow more luxuriantly, but also bloom more and the colors will be brighter. However, you should pay attention to shade in summer, otherwise the strong light will burn the leaves. 3. Temperature controlThe indoor temperature for cultivation should be controlled within an appropriate range. The temperature most suitable for its growth is 10-30℃, and the temperature suitable for flowering is 12-14℃. The temperature rises in midsummer and needs to be cooled down by spraying water, opening windows, etc. The temperature in winter should be above 5℃. 4. Reasonable fertilizationIf you want the marigold bonsai to grow better, you need to add some fertilizer. When planting for the first time and repotting, you need to add some base fertilizer to the soil, and fertilize every 7-10 days during the growing season. Fertilizers must be decomposed and not raw. |
