Russian Cypress is a low, spreading evergreen groundcover with soft feathery sprays that bronze in winter. Extremely cold-hardy and useful for slopes, foundations, and bright-to-part-shade evergreen carpets.

Care guides
Watering
Russian Cypress (Microbiota decussata) needs deep, thorough root irrigation during its first 1–2 growing seasons in Steinbach so roots push well below the prairie frost line. Water slowly at the base until moisture reaches the outer root zone—typically a deep soak once or twice a week in hot, windy weather rather than daily shallow sprinkling, which encourages weak surface roots. After establishment, water deeply during prolonged drought and while fruit or new shoots are sizing in July–August. Avoid chronically waterlogged clay, which smothers roots. This selection is rated around Canadian zone 2; snow cover helps, but dry open winters still demand that late-fall soak.
Sunlight
Russian Cypress (Microbiota decussata) should be placed in full sun, part sun, or part shade. Aim for strong morning sun and lighter afternoon conditions—about 4–6 hours of direct light is usually ideal. In Steinbach heatwaves, unfiltered late-afternoon sun can pause flowering or crisp soft foliage, so a site with dappled afternoon relief often outperforms an all-day reflective south wall. Deep shade, however, stretches stems and cuts bloom count sharply. At a mature size around 25–30 cm, give neighbouring plants enough space so they do not shade out the crown as the season progresses.
Pruning
Maintenance on Russian Cypress is minimal. In early summer after the main flush, lightly tip-prune only to maintain outline if required. Do not cut back into bare brown wood that lacks green needles or sprays—those areas rarely resprout. Remove snow-broken or winter-burned tips cleanly in spring. A deep watering before freeze-up does more for winter appearance than frequent midwinter pruning.
