New Hampshire in USDA Zones 3–6
New Hampshire spans Zones 3–6. Variety lists below are organized by zone — start with your zone for the most accurate recommendations.
Growing Microgreens in New Hampshire
Zone 5 gardeners have a unique advantage when it comes to microgreen cultivation - the moderate climate and decent growing season create ideal conditions for both indoor and outdoor production. With average temperatures that avoid extreme heat spikes, your microgreens won't bolt as quickly as they might in warmer zones, giving you better harvest windows and more consistent quality. The challenge lies in the shorter growing season and potential for late spring cold snaps that can stress young plants if you're growing outdoors.
When selecting microgreen varieties for Zone 5, prioritize cold-tolerant options that can handle temperature fluctuations and varieties that mature quickly to maximize your harvest potential. The best performers in this zone are those that thrive in cooler conditions - think brassicas, peas, and hardy greens that actually prefer the moderate temperatures. Avoid heat-loving varieties like some herbs during the peak summer months, as even Zone 5 can see temperatures that stress delicate microgreens.
The varieties I've selected for Zone 5 excel because they're either naturally cold-hardy, have short growing cycles that work well with the climate, or offer flexibility for both indoor winter growing and outdoor spring/fall production. These picks will give you reliable harvests whether you're growing on a windowsill in February or in a cold frame during shoulder seasons.

Zone 5 Growing Tips for New Hampshire
In Zone 5, you can start hardy microgreens like pea shoots, kale, and broccoli outdoors as early as mid-April, about 2 weeks before your last frost date. These cool-season varieties actually prefer the crisp spring temperatures and won't be damaged by light frosts. For more tender varieties like basil and amaranth, wait until after May 1st when soil temperatures have warmed and nighttime lows stay consistently above 45°F.
Take advantage of your moderate summers by succession planting every 10-14 days, but switch to heat-tolerant varieties like red cabbage and mustard greens during July and August when temperatures peak. During these warmer months, provide afternoon shade or grow indoors where you can control temperature. Come September, you can resume outdoor growing with fall crops - actually some of the best microgreen harvests happen in early fall when temperatures cool but you still have decent daylight hours.
Season extension is key in Zone 5. Simple cold frames, row covers, or even growing trays placed in an unheated garage can extend your growing season well into November and start it earlier in March. Many microgreens only need 7-14 days to harvest, so even brief warm spells in late fall or early spring give you harvest opportunities.
