A raised bed may be the solution for planting on excessively wet sites. Plant an evergreen with the ball of soil an inch or two higher than it grew in the nursery. Dig the planting hole at least 1 foot wider in diameter than the soil ball. After the plant has been put in position, backfill around it with good topsoil. If good topsoil is not available, mix 25 percent peatmoss, compost or similar organic material with the existing soil to provide a suitable substitute.
Winter drying is a problem of all evergreens.
The evergreen foliage may lose moisture in the winter when cold or frozen soils make it difficult for roots to replace moisture as fast as it is lost. If the summer or fall has been dry, thoroughly soak the area around the plants in late November so the plants go into winter with an adequate moisture supply to help prevent the problem. Less winter-hardy evergreens should be planted in areas protected from winter sun and wind to prevent winter damage and ensure their survival. The burlap may be left on the ball for planting. Loosen the burlap from around the trunk and tuck it under the sides of the ball.
