shrubs are to be set
It is ordinarily best to plow or spade the entire area in which the
shrubs are to be set. For a year or two the ground should be tilled
between the shrubs, either by horse tools or by hoes and rakes. If the
place looks bare, seeds of quick-growing flowers may be scattered about
the edges of the mass, or herbaceous perennials may be used.
numerous substances which contain these elements in greater or less
degrees
The food of plants consists of chemical elements, or rather, of
numerous substances which contain these elements in greater or less
degrees. There is not room here to go into the interesting science of
this matter. It is evident, however, as we have already seen that the
plants must get their food from the soil, that there are but two
sources for such food: it must either be in the soil already, or we
must put it there. The practice of adding plant food to the soil is
what is called manuring.
