Culture method and basin change of Dendrobium
Dendrobium culture should first supplement sufficient nutrients, can be diluted with compound fertilizer, cake fertilizer or fermented Amoy rice water, and then pay attention to shade maintenance to ensure sufficient scattered light. Then make sure the soil and air are slightly moist. In addition, the replacement of Dendrobium should be carried out in the dormant period and early growth stage, and should be fertilized with organic nutrient solution one month after changing the basin.
Detailed maintenance steps of Dendrobium:
1. Containers and soil
Select ceramic flowerpots with holes at or around the bottom and large caliber to ensure good air permeability and leachability. Chickens farmed with Dendrobium had better be a mixture of pine bark, sawdust, moss and small stones, in which soil can be properly mixed.
two。 Management of water and fertilizer
Dendrobium likes humid but does not have stagnant water environment, should often water moisturizing, can use sprayer to water in the form of spray. Compound fertilizer or self-made pancake water or fermented rice washing water can be diluted with water.
3. Light and temperature management
Dendrobium is a kind of plant that likes semi-shade environment, strong light can easily cause its leaves to burn and dry, or the phenomenon of short leaves and stem whitening. Therefore, attention should be paid to ensure the irradiation of scattered light during maintenance to avoid strong light. In addition, Dendrobium in the environment below 5 degrees will appear frostbite or death, so we should pay attention to keep warm in winter.
4. Management of changing pots of Dendrobium
Dendrobium needs to be changed when it has been cultivated for more than 2-3 years, and the best time is its dormant period and early growth stage. Fertilizer is not needed in the first month after the basin change, and special flower fertilizer is needed if the growth is exuberant after January.
5. Pruning of Dendrobium
Before Dendrobium germinated every spring, some withered branches and dense branches should be cut off to promote the germination of robust new stem species in the tree, and cut off dense branches to make the light transmittance moderate.
The above is about Dendrobium culture need to pay attention to some of the main points, we do a good job in the breeding period of these points basically no problem.
