for many years. The plants tolerate both acidic and alkaline soils. They
prefer slightly acidic soil, and 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 or partial shade.
Ideal pH range: 6.0 - 8.0
Most arborvitae trees are grown 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. Set the
plant in the hole and fill with soil and compost. Peat moss works well, if
you do not have any compost. Lightly tamp the soil lightly. Water generously
after planting. Promote new root growth, by keeping the soil moist for the
first few weeks after transplanting.

and tidy appearance.

Once established, Arborvitae grow with little care for many years. The biggest

not be done in the fall or winter, do so early in the season, while new growth
is still appearing.
New Arborvitae plants are propagated by seed or cuttings.

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.
