A baronial , fast - growing evergreen plant , thuja , also know as arborvitae ( Thuja spp . ) is often planted to make an attractive privacy screen around a family assemblage spot or nestling ’s play country . Although hardiness diverge among coinage , most types of genus Thuja are suitable for grow in U.S. Department of Agriculture industrial plant hardiness zone 5 through 8 . However , some are unfearing to USDA geographical zone 2 . Propagate genus Thuja by shank cutting or seeds .

Stem Cuttings

Step 1

Thuja is propagated from the current year ’s growth when stems are firm but still flexible . cut taken from older growth are less probable to rootle . Thuja requires a well - drained potting commixture such as equal parts peat and either coarse sand or vermiculite . Dipping the bottom of the root in rooting hormone just before implant aids rooting . Plant six or seven cuttings in a 6 - inch pot , just deep enough to keep the stems upright . Thuja require lovingness , and cuttings root well in systematically warm temperatures — usually in about three month . If you have a high temperature mat , determine the temperature to 68 F. Otherwise , cover the pot with a plastic bag to create a fond , humid surround . Check the cuttings and mist light if the potting mixture feel dry . However , the bag keeps the potting soil moist for several weeks .

Seeds

Extract genus Thuja seeds from female cones , which are erect with hinged scales , in fall . Place the seed in a moldable bag replete with moist peat moss and chill the seeded player in the refrigerator until outpouring . genus Thuja seeds germinate well in a small container filled with a seed - starting commixture consist of three part peat moss , one part o.k. barque and one part vermiculite or perlite . sprouting requires temperature between 54 and 59 degrees Fahrenheit . Keep the seed - start mix slightly moist but never soggy . Seeds that pullulate successfully reach altitude of 1 to 2 in in six to eight week .

Hardening

Before planting outdoors , thuja seedling grow in cautiously see conditions must be acclimated to out-of-door temperatures . The hardening off process requires about a week . Begin by moving the seedlings into a protected outdoor location for an hour . Add an hour the next day and then continue bestow about an hour every twenty-four hours until the seedlings drop at least seven hours outdoors . Plant the temper genus Thuja seedling in their lasting home .

Growing Requirements

Although thuja grows in partial shade , the plant performs best in full sunlight . Thuja tolerates nearly any type of ground , including acid soil or soil that is consistently soused or wry and rocky . However , the good development occurs in moist , well - drained , impersonal to slimly alkaline territory with a pH 6.8 and 7.2 . Amend the dirt lightly with compost or manure before engraft and then keep the region around the tree mulch with bark chips , pine needle or another natural mulch to keep the soil moist and cool . Do n’t allow mulch to pile up against the luggage compartment .
