"The object of pruning is to control and direct growth, to improve health, to increase bloom, (or fruit) production and to shape
aesthetically. It should be done in a timely manner, not postponed until the day you confront the jungle that used to be your yard – which is your expensive landscape.
It is understood that spring blooming shrubs, particularly azaleas, must be pruned as soon as practicable after blooming in order to use the new growing season to produce buds for next year’s flowers. In the case of azaleas, wherever you cut you gain three new shoots for next spring’s display.
Deciduous woody shrubs such as forsythia, spiraea and flowering quince fall into this category. They should be renovated every spring by cutting to the ground the oldest, thickest stems, enabling new shoots to develop with access to light, air and water. Crowded, thick and crossing stems are injurious to the plant’s health, appearance and flower production.
