How to fertilize Dendrobium

1. Topdressing condition

First of all, make sure that the temperature is between fifteen and thirty, which is more suitable for topdressing. If you are not in this range, you need to be cautious. Nitrogen fertilizer can be added to it during the growing period, and potassium and phosphorus fertilizer can be added when flowers and fruits are produced. Topdressing can not be carried out at noon in summer and autumn, but preferably in the evening when there is no sun.

two。 Topdressing method

First of all, dig up the soil around it, then put the fertilizer in, and then fill the soil and water it. If it is a water-soluble fertilizer, try dissolving it with water, then sprinkle it on the leaves or pour it directly with water.

3. Topdressing principle

If you apply less each time, you can apply it several times.

4. Matters needing attention

① it will stop growing during the dormancy period, metabolism and photosynthesis will be relatively poor, if we add fertilizer to it, its dormancy will be broken, plant growth will be difficult to continue, so the plant nutrients will also be consumed, the next year flowering will be affected.

② should not apply fertilizer when it blossoms, otherwise the flowers and fruits will fall, and the more serious plants may die.

Newly planted ③ can not be fertilized, because there are so many wounds that it is difficult to heal after being stimulated, and the roots will rot away.

④ cannot be fertilized under its roots, so it will be difficult to absorb and utilize, and should be applied far away from its roots according to the growth of the plant.

⑤ cannot apply heavy fertilizer or raw fertilizer to it, otherwise it will die and it will stink.

⑥ should pay attention to comprehensive nutrition, if only nitrogen fertilizer is applied to it, its flowering time will be delayed, and the flowers will not look good.

⑦ weak plants can not be fertilized casually, which is harmful to it. And there is no need to fertilize it during the seed period, until the real leaves grow.
