How to Grow Arborvitae:
Arborvitae are easy to grow and maintain. Once established they will thrive
for years with a little pruning and care. While they prefer slightly acidic
soil, they will grow in a variety of soils, from clay to sandy loam. Moist,
well draining soil is preferred, but they will tolerate extremes. Arborvitae
grow well in full sun of partial shade.
Most arborvitae are grown either as foundation plants around homes and buildings,
or a hedgerow or fence rows. After selecting a location, dig a hole deep
and wide. Mix generous amounts of compost with soil from the hole. Place
the plant in the hole and fill with soil and compost. Tamp the soil lightly.
Water generously when planting. Keeping the soil moist in the first few weeks
after transplanting will help to promote new root growth.
Pruning Arborvitae:
Once established, your arborvitae will grow with little care for years. The
biggest task is pruning. While people tend to prune them a few times a year,
pruning is best done once in the fall or early winter. If pruned in the summer,
the tips of the pruned branches can turn an unsightly brown. If you can't
prune them in the fall or winter, do so early in the season while new growth
is still appearing.
Propagation:
New Arborvitae plants are propagated by seed or cuttings.
When growing from seed, collect seeds in the fall. Start in peat pots indoors
in early spring, or sow directly into a seedbed outdoors. Transplant seedlings
into a garden several weeks later.
To grow from cuttings, cut a 4-5 inch branch of new growth. Strip away the
lower leaves. Plant in coarse, well draining sand. Keep the soil most.

Arborvitae. Snow and ice buildup can damage or break individual branches,
or the whole tree. Shrub protection against foraging deer, rabbits
and rodents is also important.
Many people use burlap to cover the plants. It's effective, but unsightly.
It can also cause mold and mildew on the plant. Another alternative
is heavy duty, multi-strand netting. The netting is made of UV protected
material, and will last for years. Selecting a green netting results in a
barely visible protection against animals, as well as protection from breakage
of individual branches. when snow and ice buildup is a problem.
