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; this should be cut back every spring.
Neillia.—Thin out every year after flowering is past, cutting back the old wood to strong young shoots.
Neviusia.—This requires the same pruning as Neillia.
Notospartium.—Requires no pruning.
