The best orchid fertilizer (which organic fertilizer is best for growing orchids)

When is the best time to fertilize orchids?

Looking at all plants in nature, it is best to fertilize them during the growth stage , because the plants at this stage are more active, have stronger absorption capacity, and have a higher demand for nutrients.

If you apply fertilizer at this time, the roots can absorb it better and new leaves will sprout and grow faster. The same is true for fertilizing orchids. It is most appropriate to apply fertilizer during the growth period.

Since different orchid species have different growth periods, the time period for fertilization depends on the species of orchid you are raising. Most orchid species need topdressing in spring and autumn. In spring and autumn, the climate is suitable and the temperature is moderate, so you can apply an appropriate amount of topdressing to facilitate the orchid's better absorption and growth.

What fertilizer is best for growing orchids?

Inorganic Fertilizer

Inorganic fertilizers, that is, chemical fertilizers, can be applied appropriately during the growth stage of orchids. Chemical fertilizers are mainly nitrogen fertilizers and potassium fertilizers. Urea and potassium dihydrogen phosphate can be applied. The urea solution can be diluted 150-200 times with water. Water the roots of orchids, and dilute potassium dihydrogen phosphate 200 times with water and spray the leaves.

Organic Fertilizer

During the growth period of orchids, organic fertilizers are mainly applied, such as cake fertilizer, fish bones, orange stalks, fallen leaves, grass, human and animal feces, etc. , which can also provide orchids with sufficient nutrients and the fertilizer effect is relatively mild.

Organic fertilizer is mainly used as base fertilizer. It must be sterilized and insecticidal, fully fermented, and mixed into the soil when potting to ensure a good supply of nutrients. It can also be used as topdressing . You can dig a hole in the soil around the roots of the orchid, apply the fertilizer into it, and cover it with soil .

Water soluble fertilizer

Orchids can also be applied with water-soluble fertilizers. Mix the water-soluble fertilizers with water and then water them to the roots of the orchids. The water-soluble fertilizers can encourage the roots to fully absorb nutrients.

Special fertilizer

When growing orchids, you can use special slow-release fertilizer for orchids, which is specially developed for orchids and can effectively promote the growth of orchid roots.
