Extended information:

1. Orchids can't be used without application, and it's even worse to apply them more or more. For example, when cymbidium grows in a pot, the soil in the pot is too fat to survive, and even if it can survive, it rarely blooms. If there is too much fertilizer in summer, the autumn leaves will be prosperous, which often leads to poor flowering of the leaves in the next spring. If autumn fertilizer is too little, it will affect the formation of underground flower buds at the turn of autumn and winter. If there is too much nitrogen fertilizer on weekdays and the leaves are too fat, so that the growth and nutrition of leaves and flowers are out of balance, there will be no flowering or less flowering.

2. Orchids like shade and are afraid of direct sunlight; Prefer wet, avoid dry; Likes fertility and is rich in humus; An environment suitable for air circulation.
