an arborvitae plant in the winter will help to encourage more
arborvitae growth in the coming growing season. Pinching back
leaves or growth tips will also encourage the new growth.
New arborvitae growth will appear a bright yellow green, contrasting
with the rest of the plant, and be very soft. As it ages,
the arborvitae growth will become harder and the color will
darken to match the tree.
arborvitae growth can be trimmed down to encourage the plant
to split and grow two branches from that location. Pruning
arborvitae growth should be done at a forty-five degree angle,
and only about a quarter inch above a lateral bud that is
pointing outward. This will not only even up the tree or shrub,
it will also help to encourage it to grow in a more steady
and complete form the following growing season.
