Louisiana in USDA Zones 8–10
Louisiana spans Zones 8–10. Variety lists below are organized by zone — start with your zone for the most accurate recommendations.
Growing Microgreens in Louisiana
Zone 9's warm, extended growing season creates unique opportunities for microgreen cultivation that gardeners in colder zones can only dream of. With nearly 290 frost-free days and mild winters, you can grow heat-sensitive varieties like cilantro and basil microgreens well into November, while starting cool-season favorites like pea shoots as early as February. However, the intense summer heat presents real challenges – temperatures above 85°F can cause rapid bolting and bitter flavors in delicate greens like arugula and mustard microgreens.
The key to success in Zone 9 is selecting varieties that either thrive in heat or can be grown during your generous shoulder seasons. Heat-tolerant options like amaranth, sunflower, and mung bean microgreens excel during summer months, while your long spring and fall seasons allow for multiple successions of cooler-weather crops. Smart variety timing lets you harvest fresh microgreens year-round, something that sets Zone 9 apart from most growing regions.
Our recommended varieties balance heat tolerance, flavor intensity, and growing reliability specifically for Zone 9 conditions. Whether you're dealing with scorching July afternoons or mild December mornings, these selections will keep your microgreen trays productive through every season.

Zone 9 Growing Tips for Louisiana
In Zone 9, timing is everything for microgreen success. Start your first cool-season varieties like pea shoots, broccoli, and kale microgreens in late February after your last frost risk passes, then plant successive crops every 10-14 days through April. As temperatures climb toward summer, transition to heat-tolerant varieties like sunflower, amaranth, and mung bean microgreens, which actually perform better in warm conditions. Indoor growing becomes crucial during peak summer – a cool basement or air-conditioned space will prevent the rapid deterioration that outdoor heat causes.
Summer growing requires extra attention to ventilation and watering frequency. Your microgreens will germinate faster in the heat but also dry out more quickly, so check soil moisture twice daily during June through August. Consider shade cloth if growing outdoors, or time plantings for late afternoon harvests before the day's heat peaks. Come September, you can resume outdoor growing with fall plantings of radish, mustard, and cilantro microgreens.
Take advantage of your mild winters by continuing production through December and January. Even when temperatures dip into the 40s, hardy varieties like kale, Swiss chard, and purple kohlrabi microgreens will germinate and grow steadily. Cold frames or row covers provide just enough protection during occasional cold snaps, extending your harvest window even further.
