The answer to 'how to install hedge' is to follow these steps to properly plant and establish a new hedge. First, choose the right hedge plants for your climate and soil conditions. Measure the area and space the plants 12-24 inches apart, depending on the mature size. Dig a trench or individual holes 2-3 times the width of the root ball and the same depth. Carefully remove the plants from their containers, place them in the holes, and backfill with the original soil. Water thoroughly to settle the soil and apply a 2-4 inch layer of mulch around the base. Prune the tops of the plants by 1/3 to encourage bushy growth. Finally, water regularly for the first year as the hedge becomes established.
Proper installation and care is important for a healthy, long-lasting hedge. If you're unsure about plant selection or have a large area to cover, it's best to consult with a professional landscaper for guidance.
