what planting zone is maryland

Maryland spans multiple USDA planting zones: it ranges from Zone 5b in the cold western mountains to Zone 8a along the warmer Chesapeake Bay and Atlantic coast.

What Planting Zone Is Maryland? 🌱

Maryland doesn’t fall into just one planting zone — it’s a patchwork of climates thanks to mountains in the west and water in the east.

Quick Scoop: Maryland’s Planting Zones

• Maryland includes six USDA planting zones.

• These zones range from 5b, 6a, 6b, 7a, 7b, to 8a.

• Western MD (Garrett County, higher elevations) is the coldest (5b–6a).

• Central belt (around Frederick, Hagerstown, parts of Baltimore area) is often 6b–7a.

• The DC–Baltimore metro and much of central/southern MD are mainly 7a–7b.

• Southern MD and coastal/Eastern Shore areas near the Bay and ocean reach 7b–8a and even small pockets of 8b listed for some counties.

Simple rule of thumb

If you’re in the mountains: think 5b–6a.
If you’re near DC/Baltimore: think 7a–7b.
If you’re close to Chesapeake Bay or the ocean: think 7b–8a.

Mini Guide by Region (Story-style)

Imagine driving west to east across Maryland in early spring:

1. Western Maryland (Garrett, Allegany)
   • Snow lingers longer, nights get pretty cold.
   • Zones 5b–6a , sometimes 6b in parts of Allegany.

 * You start seeds later and choose extra-hardy perennials.

2. Central Maryland (Frederick, Carroll, Washington, parts of Baltimore County)
   • Springs arrive sooner, but freezes still happen.
   • Mostly 6b–7a.

 * Plenty of fruit trees, roses, and veggies thrive.

3. Baltimore–DC Suburbs (Montgomery, Howard, Prince George’s, Anne Arundel, much of Baltimore area)
   • Urban heat and slightly milder winters.
   • Largely 7a–7b , some pockets nudging warmer.

 * Longer growing season, more variety in shrubs and flowering plants.

4. Southern Maryland & Eastern Shore (St. Mary’s, Calvert, Charles, coastal counties)
   • Water moderates temperatures; frosts are less intense.
   • Zones 7b–8a , with some listings including 8b segments in St. Mary’s.

 * Great for longer-season vegetables and more tender ornamentals.
