Use Thuja occidentalis 'Technito®' when you want a tidy, compact arborvitae with rich green color through the seasons. You get a dense, pyramidal evergreen that works well as a privacy screen, hedge, or vertical accent in mixed borders. Mature size is typically about 96-120 inches tall with a 48-60 inch spread, so it fits where taller, wider arborvitae would feel oversized.
Plant it in full sun for the fullest habit, but it also performs in part shade, especially where you want some afternoon relief. Choose a site with average to consistently moist, well-drained soil. Once established, keep moisture steady during extended dry periods, and mulch the root zone to reduce competition and help the soil stay evenly damp.
Space plants with their mature width in mind if you are creating a screen. Water deeply after planting and through the first growing season so roots can establish. In winter, evergreen foliage can dry out in windy, exposed sites, so a sheltered location and winter watering during warm spells can help reduce browning.
Prune lightly for shaping in late winter to early spring, or just let the plant hold its natural outline. Avoid cutting back into old, leafless wood. If you are growing a hedge, periodic shearing is usually minimal compared with faster, looser cultivars.
In many areas, deer may browse arborvitae, particularly in winter, so protect young plants if browsing pressure is high. With steady moisture and good light, you will have a reliable, year-round evergreen structure for the landscape.
