General Culture:

Easily grown in average, medium, well-drained soils in full sun to part shade. Somewhat wide range of soil tolerance, but prefers moist, well-drained loams. Intolerant of dry conditions. Best in full sun, but generally appreciates some light afternoon shade in hot summer climates such as the St. Louis area. Plants may open up in too much shade, however. Site in locations protected from cold winter winds.

Noteworthy Characteristics:

Although the species is a native American needled evergreen tree which grows 40-60’ tall, ‘Techny’ is a compact, broad-based, upright, conical-pyramidal, dwarf cultivar that typically matures to 10-15’ tall. It is noted for its rich dark green foliage that does not yellow in winter. Foliage is scale-like and appears in flat, fan-shaped clusters. This cultivar is synonymous with ‘Mission’.

Problems:

No serious insect or disease problems. Bagworms and spider mites are occasional visitors. Foliage of many arborvitaes develops winter burn (yellows) in cold, exposed sites, however this cultivar shows excellent resistance to this problem. Susceptible to damage/stem breakage in winter from ice and snow accumulations.

Uses:

Specimen, hedge or screen.
