How to water a potted Dendrobium orchid? Treat yellowing leaves this way
Dendrobium orchid is a well-known plant of the Orchidaceae family. Its flowers are graceful and noble, and its colors are elegant and beautiful, making it deeply loved by everyone. Many people like to grow potted Dendrobium orchids at home, but this flower requires certain care skills and patience, so how should a potted Dendrobium orchid be watered and fertilized? Let's learn about Dendrobium orchid care tips together with the editor below!
How to water a potted Dendrobium orchid
In spring, summer and autumn, watering is best done in the morning from 9-11 o'clock. When the summer temperature is higher than 30°C, pay attention to ventilation and moisture retention, and do not water during high temperatures. Also, after watering, turn on a circulating fan to dry the moisture on the leaves as soon as possible, so as to avoid disease.
When the winter temperature drops below 10°C, the plant will enter a certain dormant period, and watering should be stopped. If the winter temperature exceeds 10°C, watering can be done appropriately. The time for watering should be set during sunny daylight hours.
When there is too much water, the plant's growth will become slow and the roots will easily rot. You can stop watering to increase air in the substrate, and start watering again after the plant resumes growth.
What to do when Dendrobium orchid leaves turn yellow
As for the environment in which Dendrobium orchids grow, we know which environments they are suitable for. Dendrobium likes humid and semi-shaded environments, and wild Dendrobium orchids especially have higher requirements for the environment.
1. Only in a humid and semi-shaded environment will the respiration of Dendrobium orchid aerial roots be helped. If Dendrobium orchids are always grown in an environment with high temperatures, dryness and strong direct sunlight, the leaves will easily turn yellow, so the choice of environment is crucial.
2. The influence of weather and seasonal changes will affect the color changes of Dendrobium orchid leaves. When seasonal changes occur, pay attention to adding organic fertilizer. Ensure the moisture level of the leaves and help the plant improve its resistance.
3. When Dendrobium orchid leaves turn yellow, you must pay attention. If not handled in time, it will cause the entire Dendrobium orchid to dry up, so it is necessary to adapt measures to local conditions reasonably and gradually solve the main problem of yellowing Dendrobium orchid leaves.
How to handle root rot in Dendrobium orchids
1. Ventilate and control humidity to reduce root rot
Dendrobium orchid root rot may have multiple causes. You can soak the plant with fungicidal drugs such as streptomycin, then replace it with new substrate and replant it. Control the humidity of the substrate well and pay attention to more ventilation to reduce root rot.
2. Improve the care environment
Dendrobium orchids like warm and humid environments, and the environmental humidity where they grow should be above 80% to be suitable. In environments with too strong or too weak light, too high or too low temperatures, or poor soil or poor water retention, they will grow and develop poorly.
3. Disinfect in time
Cut off the rotten roots and quickly disinfect the cut surfaces. In daily care, pay attention to increasing environmental humidity and applying less fertilizer. Be sure to grow them in a semi-shaded environment, prevent direct sunlight, and lower the temperature as much as possible.
How to propagate Dendrobium orchids
1. Division propagation
So-called division propagation is to separate those plants growing together and plant them individually. Generally, they are divided from the base of the clustered stems of the old roots, reducing damage to the root system as much as possible, with the main plant becoming a separate plant. For Dendrobium orchids that grow and reproduce vigorously and have a high germination rate, division is a very suitable propagation method.
2. Bud division propagation
Older Dendrobium orchid plants often grow some new buds at the top or base, and these new buds also have root hairs. In this case, propagation by bud division is very suitable. The specific operation method is: choose division buds with more leaves and root hairs and cut them off from the mother plant.
3. Cutting propagation
The cutting principle for Dendrobium orchids is similar to general cuttings. Select fresh Dendrobium orchid stems, cut them into several sections, each section containing 2~3 nodes, and apply plant ash or disinfect appropriately at the previous cut. According to the growth direction of the Dendrobium orchid stems, insert the root part into the substrate. Because the nodes are where new buds grow, try to keep them exposed outside the substrate.
Through the above content, I believe everyone has gained a certain understanding of Dendrobium orchid care tips. Although flowers are very beautiful when blooming, behind this beauty there is always a hardworking gardener. Without this gardener, the flowers would not bloom so beautifully.
