When to plant Mountain Frost Ruby
Plant Mountain Frost Ruby 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 3 to 9 range, spring means March to May and fall means August or September. Once settled, it blooms from May 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.
