Light: Full (6+ hrs/day) to part sun (4-6 hrs/day). Siberian cypress is quite shade tolerant, but in deep shade, you may find that its habit is more sparse and open, and its foliage color is a bit muddy.
Soil: Any average soil will do, provided it is well-drained.
Water: Average water needs, some drought tolerance once established.
Fertilizing: Nothing special required. If desired, apply a granular (not liquid) fertilizer formulated for woody plants in early spring; one application per year is more than sufficient.
Pruning: Thanks to its tidy, low-growing habit, little to no pruning is required. Branches may be selectively removed if needed.
