Can orchids be grown with pine needles?

Pine needles can be used to grow orchids. Pine needles are very good for growing orchids. Pine needles are usually covered on the orchid soil after falling, which can have a certain insulation effect. The nutrients produced by the leaves after decay can also maintain the growth of orchids, but they need to be fermented in advance before use.

The pros and cons of growing orchids in pine needles

Advantages: Pine needles have good air permeability. Generally, there will be no root suffocation or water accumulation when used. They can also be used as an air layer for a small environment, which can avoid heat in summer and keep warm in winter.

Disadvantages: Pine needles will produce some bacteria or larvae when fermenting and rotting. If they are not disinfected, they will damage the roots of orchids. If they are not fermented, they will burn the roots of orchids.

How to grow orchids with pine needles

1. Fully fermented: Pine needles need to be fully fermented before use, because pine needles contain a kind of oil, which will affect the growth of the root system if used directly, but this substance can be decomposed after fermentation.

2. Prepare the soil: The fermented pine needles can be used directly. Generally, they can be spread directly on the surface of the soil when using them. They can also be mixed with the soil when planting orchids and then used as base fertilizer.
