Growing Chinese Stewartia

Plant it in part sun. It prefers moderate water. It is hardy in USDA zones 5–7. Expect it to reach about 15 ft tall and 13 ft wide at maturity, in roughly 15 years.

When to plant Chinese Stewartia

Plant Chinese Stewartia in early spring as soon as the soil is workable, or in early fall at least six weeks before your first frost, so roots establish in cool weather. For the middle of its hardy zones 5 to 7 range, spring means March to May and fall means August or September. Once settled, it blooms from June to July.

Month-by-month timing for your zone is on the planting calendar: for the middle of its range, start with zone 6 in March.
