Growing Tips for Chisago County
Plant bare-root roses in early spring as soon as soil is workable, or set container-grown plants from spring through early fall. Dig a wide, deep hole; amend with compost and a handful of bone meal. Set the graft union 1–2 inches below soil level in Zones 3–6 for winter protection, at soil level in Zones 7+. Water deeply twice weekly until established. Fertilize with a balanced rose food every 4–6 weeks during the growing season. Prune hybrid teas and grandifloras to outward-facing buds in early spring when forsythia blooms. Deadhead to encourage repeat bloom. Fall planting (Zones 5+) can improve establishment in subsequent years. Year 2+ plants deliver the fullest bloom display.
