Summer, especially wet summers, can make the hedges at your commercial property go wild. Lush leaves and baby twigs can loom over your paths and generally make your landscape look overgrown. This is never pleasant for your customers.
It is also bad for the health of your hedges. Dead branches and leaves invite bugs and encourages plant disease. The brand new growth also directs nutrients away from the roots, where the shrubs need it most, spread it too thinly through the established leaves, and essentially leave your hedge less green.
So when do you want to have your hedges trimmed?
It depends on the type of shrubs you have on your property. The best advice for most hedges is to always have it trimmed before the new growth gets bigger than a foot. Slow-growing plants need more frequent trimming, especially weak-stemmed shrubs. Shrubs in mild weather may require two to three trimmings, but shrubs in cooler weather may need to be trimmed only once after July. Your new tree or shrub does not need trimming when it is first planted, but giving them a little trim after one year is a good idea.
Shrubs and hedges should ideally look solid and full. For new hedge shrubs, pruning half the new growth in the first couple growing seasons will encourage it to grow low branches and give it the right look. Pruning shrubs before they get to their full height will also maintain its appearance.
Proper trimming can right a plant that is starting to look a little scraggly, too. If your problem shrub is deciduous, have your landscapers prune it to a foot below the desired height in the spring and then let the experts trim judiciously over the years.
