How to grow Dendrobium orchids to bloom
A guide with tips and knowledge on how to cultivate Dendrobium orchids to bloom and the correct maintenance methods for these green plants, with a detailed introduction below.
In the orchid world, Dendrobium orchids are quite famous. They are not only ornamental but also have medicinal properties. There are three methods for growing Dendrobium orchids: rock planting, tree planting, and shaded greenhouse planting, using stones, tree trunks, and small greenhouses, respectively. Dendrobium orchids are quite delicate and require shading when grown artificially, with an optimal growth temperature between 25-30°C. The phosphorus and potassium ratio needs to be increased during the blooming period. Fertilization should be stopped when new leaves appear at the top of the plant, otherwise, it will affect the quality of the blooms.
I. Cultivation Methods for Dendrobium Orchids
Rock Planting: Wrap the roots of the Dendrobium orchid with a layer of fertilizer and place them in the gaps between stones. If there are any foreign objects in the gaps, they should be cleaned out first, then the orchids are secured with strings after placement.
Tree Planting: Make a slit on the tree trunk with a knife and place the Dendrobium orchid into the crack and secure it. The new roots of the orchid will grow along the tree. Decayed trees should not be used for planting Dendrobium orchids.
Shaded Greenhouse Planting: Set up a small greenhouse, hang a curtain on the sunny side to facilitate shading during summer. In the greenhouse, mix fine sand with small gravel to make a high ridge, and plant the Dendrobium orchid seedlings in it.
II. Precautions for Cultivating Dendrobium Orchids
1. Light
Wild Dendrobium orchids usually grow in shady places or under the trees, so artificial cultivation requires shading.
2. Temperature
Dendrobium orchids enter a dormant state when the temperature is below 5°C and do not grow. The plants can easily suffer frostbite when the temperature drops below zero. It is important to keep the Dendrobium orchids warm in winter. High temperatures in summer are also not suitable, as the optimal growth temperature for Dendrobium orchids is between 25-30°C.
3. Fertilization
Fertilization begins in the second year after planting Dendrobium orchids, using decomposed manure with a 70% water and 30% fertilizer mixture, applying thin and frequent fertilization. Increase the phosphorus and potassium ratio during the blooming period. Fertilization should be stopped when new leaves appear at the top of the plant, otherwise, it will affect the quality of the blooms. After the Dendrobium orchids bloom, they enter a dormant period and fertilization should be stopped until new buds appear.
