The more you pick, the more the plant produces. Letting fruit overripen tells the plant it's time to stop.
Peonies (Paeonia lactiflora) are the crown jewels of the spring garden — magnificent, fragrant blooms in white, pink, and red that can last 100 years or more in the same spot with minimal care. Extremely cold-hardy and requiring a period of winter chill to bloom, they are most productive in Zones 3–7. Each established clump produces dozens of lush, fully double or semi-double flowers over a 2–3 week window in late spring. Virtually pest-free beyond the cosmetic presence of ants on buds (which are harmless). Once sited correctly, peonies rarely need dividing or moving.
Monroe County, Alabama is in USDA Zone 8b. The average last spring frost is March 14 and the first fall frost is November 14, giving you a growing season of approximately 245 days.
At an elevation of 177 feet, Monroe County receives approximately 51.5 inches of rainfall annually with predominantly clay loam soil.

Peonies 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.

Growing Tips for Peonies in Monroe County
Direct sow Peonies outdoors after March 14 in Monroe County when soil has warmed and frost danger has passed.
With Monroe County's clay soil (26% clay), work in 3-4 inches of compost before planting Peonies. Avoid tilling when soil is wet to prevent compaction.
With summer highs reaching 96°F in Monroe County, provide afternoon shade for Peonies and water deeply in the morning.
General growing tips
Plant bare-root divisions in fall (late September through October in Zones 3–7; November in Zone 8) with eyes facing upward and positioned exactly 1–2 inches below soil surface — deeper planting is the most common reason peonies fail to bloom. Choose a site with full sun and excellent drainage. Peonies require 6+ weeks of temperatures below 40°F (cold stratification period) for reliable bloom — they do not perform well in Zone 9+. Do not expect full bloom the first or second year; Year 3+ plants deliver the most impressive flowering. Avoid moving established plants. Stake double- flowered types before heavy blooms cause stems to flop. Cut stems to ground in fall after frost kills foliage to prevent botrytis overwinter.
