It is relatively loose and drainage well. It is ideal for planting soil.Pond sludgeAs the name suggests, is the bottom of the pond mud pond sludge. The organic matter content of this mud is high, and its disadvantages are relatively sticky. It should be mixed with garden soil or rotten leaf soil for reuse.

Q:What are the characteristics of vermiculite on flowers?
No, vermiculite can keep warm and moisturize, but vermiculite doesn't have the nutrients needed by plants, so you need to add fertilizer occasionally
Q:How to use vermiculite with orchid soil?
Bamboo root mud. Of the roots of a bamboo clump that has been planted for many years. This kind of mud because of bamboo root, rhizome and leaf and channeling bamboo sheath rot, become loose structure and good drainage, with certain fertility without too much fertile soil, suitable for the growth of orchid. The quality depends on the bamboo root mud from three factors: the first is the original soil, this is the predecessor and foundation of bamboo root mud, with sandy loam is the best; second is the bamboo planting time, lasted longer, bamboo leaves, bamboo role more fully; again from the bamboo stump far more near the bamboo stump soil better.
