Apios Tuberosa (_Glycine Apios_).--An American climbing plant which
produces in the autumn bunches of purple flowers of an agreeable
odour. The foliage is light and elegant. The plant is quite hardy. It
enjoys a light soil and a good amount of sunshine. It may be increased
by separating the tubers after the tops have died down, and planting
them while they are fresh. Height, 12 ft.

Aponogeton.--_See_ "Aquatics."

Apples.--Apples delight in a moist, cool climate. All apples will not
succeed on the same soil, some preferring clay, while others grow best
in sandy loam or in well-drained peat. For a deep, good soil and a
sheltered situation the standard form grafted on the Crab-apple is
generally considered to be the most profitable. For shallow soils it
is better to graft on to the Paradise stock, as its roots do not run
down so low as the Crab. The ground, whether deep or shallow, should
receive a good mulching in the autumn; that on the deep soil being dug
in at the approach of spring, while that on the shallow soil should
be removed in the spring to allow the ground to be lightly forked and
sweetened, replacing the manure when the dry, hot weather sets in. The
best time to perform the grafting is March, and it should be done
on the whip-handle system, particulars of which will be found under
"Grafting." Young trees may be planted in the autumn, as soon as the
leaves have fallen. Budding is done in August, just in the same manner
as roses. In spring head back to the bud; a vigorous shoot will then
be produced, which can be trained as desired. Apples need very little
pruning, it being merely necessary to remove branches growing in the
wrong direction; but this should be done annually, while the branches
are young--either at the end of July or in winter. If moss makes its
