Article Guide: Discover how to care for Dendrobium orchids to make them bloom and simple methods for cultivating Dendrobium orchids at home. Let's take a look together!
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: planting on rocks, planting on tree trunks, and growing in shaded greenhouses, using stones, tree trunks, and small greenhouses respectively. Dendrobium orchids are quite delicate, and special care should be taken to provide shade during artificial cultivation, with an optimal growth temperature between 25-30°C. During the blooming period, the proportion of phosphorus and potassium should be increased. Stop fertilizing when new leaves appear at the top of the plant, otherwise, it will affect the quality of the blooms.
Method One: Cultivation Methods for Dendrobium Orchids
Planting on Rocks: Wrap the roots of the Dendrobium orchid with some fertilizer, place it in the crevice of a rock, clean any debris from the crevice beforehand, and secure it with a rope after placing it.
Planting on Tree Trunks: Cut a slit in the tree trunk with a knife, place the Dendrobium orchid in the slit, and secure it. The new roots of the Dendrobium orchid will grow along the tree trunk. It is not suitable to plant Dendrobium orchids on dried and decaying trees.
Shaded Greenhouse Cultivation: Set up a small shaded greenhouse, hang a curtain on the sunny side for summer shading. Use a mixture of small gravel and fine sand to create a high ridge in the greenhouse and plant the Dendrobium orchid seedlings there.
Method Two: Precautions for Cultivating Dendrobium Orchids
1. Light
Wild Dendrobium orchids usually grow in shaded areas or under tree shade, so it's important to provide shade during artificial cultivation.
2. Temperature
Dendrobium orchids enter a dormant state when the temperature is below 5°C and do not grow. At temperatures below zero, the plants can easily suffer frostbite, so it's 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
Start fertilizing the Dendrobium orchids from the second year after planting, using decomposed manure, with a ratio of 70% water and 30% fertilizer, following the principle of applying thin fertilizer frequently. Increase the proportion of phosphorus and potassium during the blooming period. Stop fertilizing 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 will enter a dormant period and fertilization should be stopped until new buds appear.
The above information provides guidance on how to care for Dendrobium orchids to make them bloom and simple methods for cultivating Dendrobium orchids at home, for reference by green plant enthusiasts. It is hoped that this can help solve your problems in green plant and flower management.
