How to Cultivate Dendrobium Orchids Well
This article provides a brief introduction to the cultivation and maintenance tips for Dendrobium orchids, and will guide you through the following details.
In the orchid world, Dendrobium orchids are quite famous. They are not only ornamental but also medicinal. There are three methods to cultivate Dendrobium orchids: rock planting, tree planting, and shaded greenhouse planting, using stones, tree trunks, and small greenhouses respectively. Dendrobium orchids are relatively delicate, and artificial cultivation requires shading, with an optimal growth temperature between 25-30°C. During the blooming period, the proportion of phosphorus and potassium should be increased. Fertilization should be stopped when new leaves appear at the top of the plant, otherwise, it will affect the quality of the flowers.
1. Cultivation Methods for Dendrobium Orchids
Rock Planting: Wrap the roots of the Dendrobium orchid with some fertilizer and place it in the crevices of a stone. If there are any debris in the crevices, clean them out before placing the orchid, and then secure it with a rope.
Tree Planting: Make a slit in 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 and rotten trees should not be used for planting Dendrobium orchids.
Shaded Greenhouse Planting: Set up a small shaded greenhouse and hang a curtain on the sunny side to facilitate shading in the summer. Use a mixture of small gravel and fine sand to create a high ridge inside the greenhouse and plant the Dendrobium orchid seedlings there.
2. Precautions for Cultivating Dendrobium Orchids
1. Light
Wild Dendrobium orchids usually grow in shaded areas or under 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. When the temperature drops below zero, the orchid plants may suffer frostbite, so it is important to keep the plants warm during winter. High temperatures in the summer are also not suitable, as the optimal growth temperature for Dendrobium orchids is between 25-30°C.
3. Fertilization
Fertilization starts from the second year after planting Dendrobium orchids, using decomposed manure with a ratio of 70% water to 30% fertilizer, following the principle of applying thin fertilizer frequently. Increase the proportion of phosphorus and potassium 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 flowers. After the Dendrobium orchids bloom, they will enter a dormant period, and fertilization should be stopped until new buds appear.
