The soil is mixed with peat soil 2, vermiculite or river sand 1 and slag 1, and an appropriate amount of sheep dung can be added as base fertilizer. For individual species and varieties with poor branching, such as New Guinea impatiens, they should be pinched properly at seedling stage. High temperature drying will make the impatiens leaves thicker and not stretch, the internodes become shorter, and when the plant shape is seriously affected, it will stop growing, so it is necessary to keep the environment cool and shade properly over the summer, the strong sunlight will burn the leaves, and if the light is too weak, the plants will grow too much, the leaves will become thinner and the leaves will be light green.
