PRUNING TIPS AND RULES OF THUMB
– Identify the purpose of each pruning job. (Table 2)
– The amount of living plant material that can be re-moved at one time depends on the age and level of establishment of the plant (Table 3).
– Dead, broken, or diseased plant material can be pruned at any time of the year.
– To rejuvenate multi-stemmed shrubs, remove one or more of the oldest stems at the base each year to stimulate new shoots to arise from the base of the plant. Many flowering shrubs bloom more prolifically on younger, 2 to 3-year-old wood. Shrubs that respond well to having some of the 3+ year-old stems removed include forsythia, weigela, deutzia, mock orange and beauty bush.
– Newly established hedges should be pruned early in the growing season to promote the desired growth and density. More established hedges may be kept vigorous and dense by thinning out older branches, which will encourage new growth.”
