Hedges should be pruned from an early stage to help establish good structure and promote healthy growth. Whether the hedge is new or established, it should be tapered so it is wider at the bottom than the top. This will help ensure the lower parts receive adequate sunlight, while also helping to reduce the effects of winter damage. This is not always obtainable with older established hedges however by consulting a professional, ideally a Certified Arborist, they can assist in implementing a maintenance program to rejuvenate your cedar hedge. Remember do not trust just anybody, call a professional.
When to Trim Your Cedar Hedge
There is no written in stone answer to this question, some say spring others say fall but the truth is you can trim a cedar hedge most anytime of the year, it just depends how you are pruning it. Assuming the hedge is healthy and not under stress, May through September is the typical timeframe to trim hedges.
Should I Fertilize and Water my Hedge?
Fertilizing is a very important aspect to keeping and maintaining your hedge, fertilizing during May/June with a 30-8-8 (or similar product) will help provide your hedge with its nutrient requirements. Always ensure the nitrogen content is slow release, one application provides a boost for the entire growing season. The preferred method of application is deep root fertilization which also helps to reduce soil co mpaction. Like most trees, cedar hedges love water, during the hot/dry summer months watering once a week during the early morning or evening hours will allow your hedges to thrive. The best method to water is a drip hose installed at the base of the hedge.
