Traditionally troughs were used to hold water and feed for enclosed livestock. Today most troughs are produced to be used as planters. A planter is a container that holds plants. What are garden troughs used for? Similar to window boxes, troughs are excellent for displaying different groups of flowering plants with their longest side often placed against a wall. As they can be very large, and sometimes deep, it is possible to create an array of artistic effects. One can plant larger, upright or climbing, plants towards the back, providing a great backdrop to the smaller plants in front. One can plant two larger plants around another, drawing the eye towards the center. In some, one can even plant trees that are perfect for lining paths. Plant troughs look great together and are often spread apart evenly when lining walls or paths. They can be placed in borders, providing a great visual stimulus in comparison to dirt. Sometimes troughs are placed on stands that can add verticality to the garden. What troughs do Primrose have for sale?
