COMPOST, in gardening, is a mixture of several earths, earthy substances, and dungs, either for the improvement of the general soil of a garden, or for that of some particular plants. Almost every plant delights in some peculiar mixture of soils or compost, in which it will thrive better than in others. The most remarkable and generally useful of these, are taken notice of under the description of the several botanical articles, as they occur in the order of the alphabet.
