Composts, therefore, should contain these decomposing matters in such proportion, as to give the plants, to which they are applied, the vigour required. If leaves are re(juired to be largely developed, the compost can be scarcely too rich ; for the greater the quantity of food imbibed by the roots, the greater will be the surface of leaves requisite for its elaboration. But if flowers and fruit, as well as leaves, are desired, the composts, if excessively rich, will cause these to diminish in number and size, the flower-buds pass- ing into leaf-buds for the reason already alleged. Composts must also duly regulate the amount of moisture supplied to the roots, totally independent of drainage, as compost retains to them moisture b
