How to propagate Thuja?
Thuja is propagated from the current year's growth when stems are firm but still flexible. Cuttings taken from older growth are less likely to root. Thuja requires a well-drained potting mixture such as equal parts peat and either coarse sand or vermiculite. Dipping the bottom of the stems in rooting hormone just before planting aids rooting. Plant six or seven cuttings in a 6-inch pot, just deep enough to keep the stems upright. Thuja requires warmth, and cuttings root best in consistently warm temperatures -- usually in about three months. If you have a heat mat, set the temperatures to 68 F. Otherwise, cover the pot with a plastic bag to create a warm, humid environment. Check the cuttings and mist lightly if the potting mixture feels dry. However, the bag keeps the potting soil moist for several weeks.
How to grow thuja from cones?
Thuja seeds germinate well in a small container filled with a seed-starting mixture consisting of three parts peat moss, one part fine bark and one part vermiculite or perlite. Germination requires temperatures between 54 and 59 degrees Fahrenheit. Keep the seed-starting mix slightly moist but never soggy. Seeds that germinate successfully reach heights of 1 to 2 inches in six to eight weeks.
How long does it take for thuja seedlings to harden?
Before planting outdoors, thuja seedlings grown in carefully controlled conditions must be acclimated to outdoor 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 adding about an hour every day until the seedlings spend at least seven hours outdoors. Plant the hardened thuja seedlings in their permanent home.
What type of soil does Thuja prefer?
Thuja tolerates nearly any type of soil, including acidic soil or soil that is consistently wet or dry and rocky. However, the best growth occurs in moist, well-drained, neutral to slightly alkaline soil with a pH 6.8 and 7.2. Amend the soil lightly with compost or manure before planting and then keep the area around the tree mulched with bark chips, pine needles or another natural mulch to keep the soil moist and cool. Don't allow mulch to pile up against the trunk.
What is thuja plant?
A stately, fast-growing evergreen, thuja, also known as arborvitae (Thuja spp.) is often planted to create an attractive privacy screen around a family gathering spot or children's play area. Although hardiness varies among species, most types of thuja are suitable for growing in U.S. Department of Agriculture plant hardiness zones 5 through 8. However, some are hardy to USDA zone 2. Propagate thuja by stem cuttings or seeds.
What is thuja evergreen?
The symmetrical profiles of Thuja (Thuja spp.) evergreens adorn landscapes and gardens in U.S. Department of Agriculture plant hardiness zones 3 through 8 with spheres, pyramids and columns of dense, yellow to deep green foliage. Five native thuja species -- commonly called arborvitae -- grow across the United Sates. Of them, American arborvitae (T. occidentalis) has produced the most commercial cultivars, including 1 1/2- to 2-foot "Nana" and 25-foot high "Fastigiata." Propagate pest-and disease-resistant arborvitae from stem cuttings.
How to propagate arborvitae?
To propagate several plants from one arborvitae, harvest a single large branch and make individual cuttings from its tip and twigs. The fewer cuts, the better; multiple wounds raise the arborvitae's exposure to fungal, bacterial and pest infestations.
What is the best way to grow arborvitae?
Arborvitae cuttings root best in sterile pots containing a sterile, moist mixture of 50 percent peat moss and 50 percent river sand. This mix encourages flexible, well-branched roots. Four-inch clay pots with drainage holes make inexpensive and effective containers. To kill any decay-producing organisms, oven-heat the pots until the center of the medium registers a temperature of 140 degrees for 30 minutes.
How to cut arborvitae?
The best arborvitae cuttings come from branches with healthy, well-shaped new growth harvested in the early morning. Use a sharp knife or pruning shears to remove a 4- to 5-inch length of the branch, measuring backwards from its tip and cutting just beneath a set of needles. Wrap the cuttings in wet paper towels and place them in a dark plastic bag to prevent them from drying out before you pot them .
When to harvest arborvitae?
Arborvitae stems are ready for harvesting in late summer or fall, when the plants have finished their active growing season. The branches are firm enough to snap easily when bent.
