Green Giant thujas (Thuja plicata "Green Giant") are fast-growing, pest-resistant evergreens with scaled foliage. They survive conditions that seriously set back needled evergreens, and tolerate sunny sites, pollution and brief drought. Homeowners, however, often underestimate the mature size of these trees, which can reach 50 feet tall or more. Crowded trees encourage mites, bagworms, blight and other problems, as well as detract from the landscape. Plan your privacy screen, windbreak or greenbelt and enjoy the long-lived Green Giant for many years.
Things You'll Need
Graph paper
Pencil
Gloves
Measuring tape
Shovel
Tarp or wheelbarrow
Call your utility company and request that it mark any underground utility lines in the planting area. This service is usually free, but it often takes at least a day to schedule and complete. Ask the utility company representative about planting or digging regulations if the utility lines run through the planting area.
Plot the thuja planting site on graph paper, to scale. Determine how many mature plants the area will support. Sketch in potential thujas where they will block unwanted views but will not interfere with overhead power lines or underground utilities.
Set container-grown thujas in the landscape according to your sketch. Space the planting sites 12 to 15 feet apart for the best privacy screening. Measure the distance between plants and adjust them as needed to keep the appropriate distance from any neighboring plants and utility lines.
Dig the planting holes, placing the excavated dirt on a tarp or in a wheelbarrow. Make the holes only as deep as the root ball of the container and two to three times as wide. Remove the container and cut or release any bound or circling roots.
Place the root ball in the planting hole and backfill firmly. Keep the root ball slightly above ground level to allow for settling. Form a watering basin at the thuja's drip line with the remaining dirt, and water the plant well.
