Maryland spans more than one climate: Zone 7 is the most common zone, but the state runs 6b to 7b. That's why the planner works from your ZIP code's frost dates, not your zone: mountain and coastal gardens in the same state can be three weeks apart.
Maryland growing notes
Maryland's humid summer makes curing the hard part.
Zone 7 gives you a real choice of type
Maryland's winter, spanning zone 6b in the western counties to 7b along the Bay, is cold enough to satisfy a hardneck garlic's chill requirement almost everywhere in the state, which is not true of warmer, more southern mid-Atlantic ground. That makes Maryland one of the few states where both hardneck and softneck genuinely thrive, rather than one type clearly beating the other.
Hardneck types like Music and German Extra Hardy reward the grower with scapes, the curling flower stalk to snap off and cook, and slightly larger cloves that are easier to peel. Softneck types like Inchelium Red skip the scape but store 2 to 3 months longer in a home pantry, which matters more to a gardener planning to eat garlic through the following winter than one who wants scapes. Either way, plant cloves 2 inches deep and 6 inches apart with the pointed tip facing up, so the shoot has the shortest possible path to the surface.
The part that actually trips growers up: drying it out
Growing garlic in Maryland is not the hard part. Curing it is. Chesapeake humidity routinely sits well above the level that slows garlic from drying properly, and bulbs cured outdoors on a covered porch here can take twice as long to finish as the same bulbs would in a drier climate, with real risk of mold setting into the neck before the outer wrappers seal.
The fix is moving air, not more heat: hang bulbs in loose bunches or lay them on a screen with a box fan running nearby, out of direct sun, for 3 to 4 weeks rather than the 2 weeks a drier state might need. Check bulbs weekly by squeezing the neck; it should feel dry and papery all the way through, not soft, before you trim roots and tops for storage. A garage or covered shed with the door cracked for airflow works better than a closed porch, where humidity just pools right back around the drying bulbs.
Match the bed to your side of the state
West of the Bay, Maryland's Piedmont clay holds water long after a rain, and garlic cloves sitting in wet clay through a soggy winter are prone to basal rot before they ever get the chance to sprout. Raise the row 4 to 6 inches and work in compost so cloves are never sitting in standing water during the coldest, wettest months.
On the Eastern Shore, sandy loam drains fast enough that rot is rarely the issue, but the same soil leaches nutrients before spring growth kicks in. A light nitrogen feeding as soon as green shoots appear in late winter makes up for what the sand let wash through over the cold months. A 2-inch mulch of straw over the row through winter helps both soil types, holding moisture in sand and moderating the freeze-thaw cycles that can heave cloves right out of clay.
In Maryland: watch for
The pests that find garlic here.
A middle-length season, about 210 frost-free days, means garlic overlaps onion thrips for a stretch each summer. Check plants every week or two and treat early.
Silvery streaks and curled leaf tips in hot spells.
Organic fix: Insecticidal soap or neem; hang sticky traps.
Seedlings wilt; white maggots in the bulb base.
Organic fix: Float a row cover over the row; rotate beds each year.
Pale patches with fuzzy gray growth in damp weather.
Organic fix: Space for airflow, water early in the day, spray neem.
White rot
Yellowing and dieback, then wilt; fluffy white mold at the bulb base and roots so rotted the plant lifts straight out.
Organic fix: No cure once it is in the soil. Plant clean stock, never follow onions with onions, and keep infested soil off tools and boots.
Your season math: Maryland gives garlic about 210 frost-free days, and it needs roughly 240 days to a first harvest. It's a one-planting crop, so time that single sowing well.
