What are the roles and effects of earthworms in orchid growing?

This article only discusses the traditional method of growing orchids

I. The living environment of earthworms:

Since I am an angling enthusiast, I have studied fishing bait quite a bit. The earthworm is a common and inexpensive fishing bait. There are many varieties of earthworms, and which fish like which quality of earthworm, so for me the earthworm's living environment is completely familiar, and there is no need to say more here. How can you dig up more earthworms? This article focuses on describing their living environment as follows.

Environments where earthworms find it very hard to survive: First, places with heavy standing water have none; second, places that are excessively dry also have none; third, land with no fertility, such as pure yellow clay soil or places of pure sandy soil and stones, has even fewer; fourth, land that is compacted and hard and where the soil layer exceeds one chi has almost none.

Environments suited to earthworm survival: under the black soil beneath the eaves, beside the soil heaps of rotting manure piled up in rural areas, in farmers' vegetable fields, under the leaf mold beneath trees, beside garbage dump sites, and so on, but these places must not have standing water and must not be too dry; the looser and more airy the soil, the more earthworms you can dig up.

II. The effects of earthworms on orchids:

1. Earthworms continuously till the soil in the orchid pot, keeping the growing medium in the pot from becoming compacted for a long time;

2. Earthworms can swallow and consume the not fully rotted growing medium and rotten orchid roots in the orchid pot, and earthworm castings are beneficial to orchid growth;

3. At certain times earthworms can also send out special signals: for example, if the orchid pot is too dry, too wet, or too hot and stuffy, they cannot help but crawl up onto the surface of the pot one after another, and it is up to orchid growers to decide how to deal with it;

4. Earthworms do no harm to healthy orchid roots. When repotting in the past I observed this, but unfortunately I have no physical photos (quoting ----- words after "Who Moved My Cheese" -- repotting (comic strip) conclusion by the orchid grower Xiashan Cao: earthworms have never gnawed orchid buds or orchid roots!), and they cannot be equated with root-eating pests such as cutworms and grubs.

III. Conclusion: Earthworms and orchids can coexist peacefully.

These are my personal views, and I hope to discuss them together with fellow orchid growers.
