Conditional — Some Areas
pomegranate (zones 7-10) has limited zone overlap with Missouri (5b-7a). Only zones 7-7 in the state are suitable.

Missouri Has
- USDA Zones: 5b-7a
- Last Frost: Apr 5 - Apr 25
- First Frost: Oct 5 - Oct 30
- Annual Rainfall: 34-50 inches
- Common Soils: Silt loam, Clay loam, Loess

Growing Season Fit
Zone compatibility says you can survive winter here. Whether the growing season is long enough — and warm enough — is a different question.
Frost-free days
Pomegranate wants 180+ frost-free days; a typical Missouri site sees ~190 (NOAA Climate Normals). That leaves tight; use transplants and pick early-maturing cultivars.
Growing degree days
Pomegranate needs ~3000 GDD (base 50°F) to ripen. The state median runs ~3850 GDD (USDA NRCS county aggregates), so Missouri's typical season clears that easily.
Chill hours
Pomegranate requires ~100 chill hours (32-45°F dormancy window). Missouri typically banks ~1050 chill hours per winter (MSU Extension method), which keeps this plant on track.
Climate aggregates derive from USDA NRCS county-level hardiness data + Cornell CALS Extension GDD-by-region tables + MSU Extension chill-hours-by-zone (1991-2020 NOAA Climate Normals baseline).
Soil + Drainage Fit
Pomegranate likes near-neutral soil (pH 5.8-8.5). That's the common-ground band across Missouri's silt loam and clay loam — a soil test confirms it for your site. Drainage matters: this plant wants well (dry spells). If your Missouri site is heavier clay or sits in a low spot, raised beds or amendment with compost solve it.

Pomegranate in Missouri — Quick Answer
- Verdict: Conditional — Some Areas
- Plant Zones: 7-10 (USDA PLANTS Database)
- State Zones: 5b-7a (USDA ARS PHZM 2023)
- Growing Season: Apr 5 - Apr 25 to Oct 5 - Oct 30 (NOAA Climate Normals)
- Days to Maturity: 1095 days
What Else to Consider
Zone compatibility tells you about winter cold survival — but Missouri growers also need to think about:
Highly variable weather with late frosts and early heat
Heavy clay soils in many regions
Ozark soils are thin and rocky
Pollinator + Wildlife Value
Pomegranate draws pollinators (moderate value, USDA PLANTS Database). Planting it near vegetable beds can lift fruit set on neighboring crops. Deer pressure is meaningful across much of Missouri; pomegranate is listed as deer-resistant (USDA PLANTS Database), which makes it a safer pick for unfenced sites.
Missouri Cooperative Extension
For Missouri-specific cultivar recommendations, planting calendars, and pest pressure for pomegranate, the canonical source is MU Extension. Their fact sheets carry the local trial data we can't generalize across 50 states.
