culata grandiflora_ should _always_ be cut back to
within two inches of the old wood.

[Illustration: _HYDRANGEA PANICULATA AND VAR. GRANDIFLORA._]

HYPERICUM.--These should be cut back fairly hard in early spring, as
they all flower on the young growth.

INDIGOFERA.--Cut down every spring, as they flower on the young wood.

ITEA.--Keep the growths thinned and cut away all old wood.

JAMESIA.--This should be treated as the preceding.

JASMINUM.--_J. fruticans_ and _J. humile_ are shrubs which should be
thinned regularly; and _J. nudiflorum_ and _J. officinale_ are climbers,
which should be spurred in after flowering.

KALMIA.--Remove seed-pods as soon as the flowers are past.

KERRIA.--Cut away the old wood to encourage the young growths, which
yield the best flowers.

LABURNUM.--These should be thinned after flowering, cutting away the old
or weakly wood, and shortening any long or straggling shoots.

LAVANDULA.--Cut away all flower-spikes after they are past.

LEDUM.--Remove seed-pods after flowering.

LESPEDEZA.--See DESMODIUM, which it much resembles.

LEUCOTHOE.--_L. axillaris_ and _L. Catesbaei_ flower much better if the
old growths are removed and strong young shoots encouraged. The rest of
the genus require no pruning.

LEYCESTERIA.--Thin out old growths every spring.

LIGUSTRUM.--_L. ovalifolium_ and its golden variety are all the better
for being cut down each winter while in a young state. The remainder
merely require an occasional thinning.

LIRIODENDRON.--Requires no pruning.

LONICERA.--The shrubby Loniceras are nearly all inclined to become very
thick and full of weakly shoots if not well looked after. A thinning out
should take place after flowering is past. The climbing Honeysuckles
should only be pruned sufficiently to keep them within bounds.

LYCIUM.--These should be served the same as the shrubby Loniceras, but
the operation should be performed in autumn or winter, as they flower
practically all the summer.

LYONIA.--Requires no pruning.

MAGNOLIA.--Generally speaking, the Magnolias should not be pruned, but
cut away useless or decaying wood. Every wound, however small, on a
Magnolia should be tarred over immediately.

MICROGLOSSA.--The solitary shrubby representative of this is _M.
albescens_, which should be cut down in winter, as it flowers best on
the young wood.

MYRICA.--An occasional thinning is sufficient for this genus.

MYRICARIA.--Flowering on the young wood; t
