Is there such a thing as all-purpose potting soil?
Plants have various soil preferences, and in cases where these are pronounced, special soil mixtures are suggested. If you perform a search for your plant species, the results will include this information. However, a good general-purpose mixture can be made by combining 2 parts loam, 1 part humus, and 1 part sand or vermiculite. Additions of small amounts of well-rotted manure and bone meal help to enrich the soil, but are not essential.
