1. Sterilization is not strict. Lan Miao new pot on the basin without serious cleaning, cleaning, disinfection, drying roots, broken roots wounds too late to heal, the harmful bacteria infection and slowly decay. Fat New blue basin, should be soil cultivation, should not fertilize. After 1 to 2 years of cultivation, until the new root growth after fertilization. Because just after the pot of blue seedlings toss several times, the constitution is very weak, there must be a very long “service basin” process. Mainly by the root and the bulb storage of nutrients to maintain life, then too much fertilizer will reverse osmosis roots, resulting in the root system deflated
