Roses (Rosa spp.) are the world's most beloved flowering shrubs, grown for centuries for their exquisite blooms, fragrance, and versatility. Modern repeat-blooming cultivars deliver continuous color from late spring through the first hard frost, while old garden roses typically offer a single magnificent spring flush. Hardy shrub roses such as the Knock Out® and Canadian Explorer series tolerate Zone 3–4 winters without protection. With correct siting (6+ hours of sun, good air circulation), disease- resistant varieties thrive with moderate maintenance.

Roses Heat Requirements (GDD)

What are Growing Degree Days (GDD)?

Growing Degree Days measure the total warmth your plants receive during the growing season. Think of it as a "heat bank" — every day above 50°F deposits warmth that helps your plants grow.

Each plant needs a certain amount of accumulated heat to mature. If your county provides more GDD than the plant needs, it's a great fit. If it's close, you may want to choose faster-maturing varieties or start seeds indoors to get a head start.

Roses needs ~2,160 GDD — county provides 3,152 GDD Excellent fit

Growing Tips for Roses in Lawrence County

General growing tips

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.
