Chap. 46 The Proper Mode of Manuring Trees
The same precautions, too, are to be regarded in manuring. Though manure is grateful to the tree, still it is necessary to be careful not to apply it while the sun is hot, or while it is too new, or more stimulating than is absolutely necessary. The dung of swine will burn3246 up the vine, if used at shorter intervals than those of five years; unless, indeed, it is mixed with water. The same is the case, too, with the refuse of the currier’s workshop, unless it is well diluted with water: manure will scorch also, if laid on land too plentifully. It is generally considered the proper proportion, to use three modii to every ten feet square; this, however, the nature of the soil must decide.
