Choosing the Location: For Boxwood Shrubs, select an area that gets partial shade where their roots can benefit from cooler temperatures. This is particularly important in warmer climates. However, they can tolerate full sun. In hot, humid tropical climates nematodes may be an issue. In severe winter weather, the wind may cause the leaves to experience winter burn. Covering the plants before this happens will serve them well.
Preparing for Planting: Boxwoods need the soil to be well-drained and fertile. Adding topsoil and organic compost will help add nutrients. Too much moisture may cause them to develop root rot. his is evident by patches of yellowing or off-color leaves. You may also add coarse sand to improve drainage, if necessary. Never plant them near downspouts or any area that stays wet, or is slow to drain. They can grow in soil from slightly acidic to slightly, preferable in the 5.8-7.5 range, although they can tolerate soils with lower pH.
It is a good idea to check your soil’s pH before planting your boxwoods. If necessary, you can add proper amounts of lime or sulfur and fertilizer to promote optimal plant growth.
Planting: For your boxwood to thrive, dig a hole as deep as the container and twice as wide. Fill in the hole with good soil that is porous, like good quality potting soil. This will enable the roots to grow more rapidly and get established sooner. Be sure not to plant than deeper than the surrounding dirt.
Once your Boxwood Plant is in its hole, gently firm the soil as you add water to remove any air pockets. Water 5 to 10 minutes to be sure the moisture goes deep. This will encourage the roots to grow deeper and be less effected by drought and heat. Cover the area around the boxwood with 2”-3” of mulch that extends about 12” out from the stem of the plant. Good mulch to use includes pine needles, pine bark or wood chips. This will help maintain even moisture and insulate the roots from damages of heat. This will also help reduce weeds that can compete with your shrub for nutrients and moisture.
