When to plant Mountain Stewartia

Plant Mountain 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 8 range, spring means March to May and fall means August or September. Once settled, it blooms from July to August.

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