How do you fertilize and keep old privet hedge plants healthy and productive?
It is by fertilizing at least twice a year and by pruning yearly that old privet hedges (Ligustrum spp) can be kept healthy and productive.Specifically, privet hedges benefit from fertilizer applications in fall and in spring. A summer of droughts calls for an extra fertilizer application, such as during the hottest month. Additionally, privet hedges respond well to yearly pruning away of competing, damaged, dead, decaying or dying branches.
