Determine the placement of your hedgerow and dig planting trenches prior to purchasing your plants. Ensure that the trenches are deep enough to accommodate the roots of your chosen plants.
Plant your hedge varieties with a few feet between each plant. This allows the hedges to establish themselves without competition. Fill in open areas for the first few seasons -- until the hedge plants fill out -- with smaller flowering plants or grasses.
Edge your hedgerow with a mound of dirt on either side. This helps the hedge retain water.
Mulch the hedgerow at least once per season to prevents weeds. In the beginning, mulch and feed your hedges with diluted shrub food and root stimulator bi-weekly to encourage roots and healthy growth.
Water as needed for your species of plants. Most plants need daily watering during hot months and weekly watering in fall and winter.
Prune regularly to remove dead branches, to encourage growth and to maintain the shape of your hedgerow. Evergreens and plants that bloom in the spring should get a thorough pruning at the beginning of winter.
