Planting
Plant evergreens in spring, summer or fall.
Dig hole a little larger than the size of the root ball.
Remove plastic pot; if roots appear matted use your fingers or cut the roots to loosen them. Doing this will also encourage root growth.
Set the plant into the hole at the same depth as the soil line on the plant; no roots should protrude about the soil.
Backfill with soil; compact the soil around the plant enough to hold the plant firmly in place.
Water thoroughly.
Do not put fertilizer in the planting hole. A slow release fertilizer is available in granules that can be sprinkled around the plant at the top of the soil and watered in.
Watering
Water newly planted evergreens regularly during the first year of planting; sandy soils may need more water, while clay may need less.
Water evergreens thoroughly in fall before the soil freezes to help prevent winter burn.
Mulching
Adding mulch around your plant will help retain soil moisture and reduce weeds. Organic mulches as they decompose will add organic matter to the soil.
Add 2-4 inches of mulch around your plant, keeping it 1-2 inches from the trunk.
Fertilizer
Apply fertilizer in early spring or late fall. Use a fertilizer specific to evergreens. Apply according to the label.
