lant that
naturally remains small, although some varieties are more adaptable
than others to the purpose.
If seeds of the natural diminutive apple-tree are sown, a variety of
trees and apples may be expected. The fruits would probably be
inferior. Probably the stature would vary between different seedlings.
If we are to get the effect of dwarfness, we must be sure that the
stock is itself really dwarf. Therefore, to eliminate variation and
also because seeds of natural dwarf apples may not be had in
sufficient quantity, the stocks are propagated by layers rather than
by seeds.
The diminutive tree, when well established, is cut off near the
ground. Sprouts arise. Some kinds sucker very freely. If earth is
mounded up around the sprouts, roots form on them and the sprouts may
be removed and treated as if they were seedling stocks. Usually the
mounding is not performed until the shoots have made one season's
growth. Gooseberries and some other plants are often propagated by
mound-layers. In the case of the gooseberry, however, it is desired
that the layer reproduce the parent--it may be Downing or
Whitesmith--and therefore it is planted without further manipulation.
But in the case of the apple, we do not want the layer to reproduce
the parent, for the parent would probably bear an inferior fruit since
it does not represent an "improved" or recognized variety; therefore
the layer is grafted or budded with the particular variety we desire
to grow as a dwarf tree.
Dwarf trees are grown in America, if at all, only in gardens, where
extra attention may be given them. Only high-class kinds should be
attempted on dwarfs, for the quantity-production of commercial apples
must be obtained by less intensive methods on cheaper lands.
Better fruits often are grown on dwarf than on standards, for two
reasons: It is usual to propagate only the best varieties on dwarf
stock; the little tree must receive extra care in pruning and in every
other way. Its bushel of apples must be choice, every one, to make the
effort of growing the tree worth the while. Under European conditions
where land is high-priced and labor has been relatively cheap, it is
possible (and common) to raise apples on dwarfs for market, as it is
profitable to terrace the hillsides with human labor; but in North
America the conditions are practically the reverse and the dwarf tree
cannot compete with the standard orchard tree.
