Companion planting is an excellent way to improve your garden. Running a hedge trimmer over a row of shrubs might make them look much neater and may even look like a hedge, but for a great hedge, a little extra care will go a long way. A well planned hedge will give better results for less work as the hedge matures. Choosing the most appropriate plant for your garden design and hedge requirements will be very important. By choosing a hedge plant with an approximate mature height similar to the desired hedge height will mean significantly less trimming is required to maintain the size and shape of your hedge.
