Soil Amendments for Succulents
I just recently browsed the aisles of my local pet supply chain-store, and came across some products that might have some use as amendments when mixing up potting mediums.
There is a product called "crushed, oyster-shells" and it's gritty, flaky, and might be a source of calcium.
Also, there are bags of granulated walnut shells, also a fine grit. IF this has a use in potting mixes, do you think that the poison that comes from walnut trees will be in the shells also?
Activated, granular charcoal...removes toxins from soil?
Coconut husk chips, coir, sterilized corn cob granules, (could these be used as an organic supplement as it breaks down)?
Then there's the rabbit-type foods that really are pelletized plants, and vitamins. Can these be used as a type of green manure?
Hydroponic supply stores have hundreds of products, like seaweed pellets, bat guano, soil-improvers, plant/root tonics, Humic acid additives, macro-micro nutrient powders, etc. Any good?
What about expanded shale products for improving soil texture, and drainage?
I mentioned all these products because I am curious to know if they can have a place in growing mediums.
Thanks for any comments.
