2. The bottom of the substrate is made of coarse stones or bricks to facilitate drainage and ventilation; Use pebbles or broken bricks in the middle layer, and try to choose materials with good water absorption, such as ceramsite, sapphire and broken bricks; The upper layer is fermented pine trees.
3. When planting Dendrobium, be careful not to bury the stems of seedlings in the substrate, which can cover most of the roots, and then water them after planting.
4. Fertilization: Sprinkle a special slow-release fertilizer for orchids around the Dendrobium root, then cover it with a small amount of bark and water it again.
5. After planting, place the tin potted plants in a well-ventilated semi-shaded environment, such as a window sill with good light, a balcony without direct sunlight or a shade.
Note: When potted Dendrobium is in the open air, Dendrobium should always be placed under the big leaf plants on the balcony. Large-leaved plants block the strong light for Dendrobium. Growers usually only water it, and they have never used pesticides. Fertilizer is a slow-release fertilizer added when planting, and later some healthy and multi-fertilizer is added. Dendrobium buds grow rapidly in rainy weather and slowly in sunny days with high temperature and low humidity. Usually management is to water several times a day on a sunny day.
