Can Chinese medicine residue be composted without soil? A detailed guide to composting methods

Many people compost Chinese medicine residue to use as fertilizer for growing flowers, and some even plant flowers directly in the composted Chinese medicine residue. So how exactly is Chinese medicine residue composted? Can Chinese medicine residue be composted without soil?

1. How exactly is Chinese medicine residue composted?

1. Prepare a container for composting the Chinese medicine residue, then spread a layer of dry soil on the bottom of the container (this step can be omitted if you are composting Chinese medicine residue fertilizer without soil);

2. After spreading the dry soil, spread the Chinese medicine residue evenly over the dry soil, then spread another layer of dry soil;

3. After spreading, cover the container with a plastic bag, then place it in a spot with direct sunlight for sun exposure;

4. Because the medicine residue itself contains water, there is no need to add extra water during composting;

5. If you want to compost Chinese medicine residue without soil, you need to crush the residue and dry it out a bit, so that not too much moisture remains, to avoid mold.

2. Can Chinese medicine residue be composted without soil?

Chinese medicine residue can be composted without soil, but it is somewhat harder than composting with soil; adding soil can speed up the fermentation of Chinese medicine residue. When composting Chinese medicine residue alone without soil, on the one hand you need to prevent the residue from molding, and on the other hand you must not be impatient. Generally, in winter it takes about half a year to compost, and in summer about 3 months. If the temperature is especially high, it can be composted in about a month.

3. Will Chinese medicine residue used as fertilizer burn roots?

If the Chinese medicine residue is composted with soil and used as fertilizer, it generally will not burn roots. An even simpler method is to spread the Chinese medicine residue directly at the bottom of the pot, then add soil on top for planting. This also helps with air and water permeability, and because a soil layer separates it, there is no need to worry about burning roots.

If pure Chinese medicine residue fertilizer is used for planting without mixing in soil, then whether it burns roots depends on the specific condition of the plant.
