How Long Do Microgreens Last After Harvest?
Quick answer
Fresh microgreens typically last 5–10 days after harvest when stored in a sealed container in the refrigerator at 35–40°F; microgreens delivered the same day they are cut have the longest usable window and highest nutritional value.
Shelf life depends heavily on how fresh they were when you got them. Here's what to expect and how to get the most out of every delivery.
Typical shelf life of fresh microgreens
Fresh microgreens last approximately 5 to 10 days after cutting when stored properly in the refrigerator. The exact window depends on the variety — delicate varieties like pea shoots and sunflower tend toward the shorter end; sturdier varieties like radish and broccoli last toward the longer end.
The single biggest factor in shelf life at the point of purchase is how long ago they were cut. Grocery store microgreens are typically harvested days before they reach the shelf and have been in cold storage and transit since. When you get them home, the usable window is already shorter.
Microgreens from Robby Ds Lil Greens are cut Friday morning and delivered the same day — which means the full 5-to-10-day window is intact when they arrive.
How to store microgreens correctly
Store cut microgreens in a sealed container or resealable bag in the coldest part of your refrigerator — ideally between 35°F and 40°F. Do not wash them until you're ready to use them; moisture accelerates decay.
If you bought a living tray (still rooted), keep it at room temperature away from direct sunlight and water the base lightly every day. Living trays let you harvest on your own schedule and can stay fresh for seven days or more — you harvest as you need, keeping the rest of the tray alive.
Signs that microgreens have turned
Microgreens past their prime will show yellowing, limpness, a slimy texture on the stems, or an off smell. Yellowing is usually the first sign — the chlorophyll is breaking down. At that point the flavor and nutritional value have both declined significantly.
Slight wilting doesn't necessarily mean they're bad. A brief rinse in cold water and a few minutes in the fridge can revive slightly wilted microgreens. Sliminess or smell is the line — don't eat past that point.
When freeze-dried is the better choice
If you travel frequently, live outside the delivery zone, or want a daily supplement rather than a fresh green, freeze-dried microgreen powder is the practical alternative. The freeze-drying process removes moisture at low temperatures, preserving most of the nutritional profile in a shelf-stable form.
Robby Ds Lil Greens' freeze-dried organic pea microgreen powder ships to all 50 states with a shelf life measured in months. Two scoops in your morning coffee or smoothie provides the nutritional equivalent of a serving of fresh pea microgreens.
Frequently asked questions
How long do fresh microgreens stay fresh?
Approximately 5–10 days after cutting when stored in a sealed container in the refrigerator at 35–40°F. The window depends on variety and how fresh they were at purchase — same-day delivery maximizes the usable window.
What's the best way to store microgreens?
In a sealed container or resealable bag in the coldest part of your fridge. Don't wash until ready to use — moisture speeds up decay. Living trays can be kept at room temperature and harvested daily.
Can you freeze microgreens?
Fresh microgreens don't freeze well — the cell structure breaks down and the texture becomes limp. For a shelf-stable option, freeze-dried microgreen powder is the better choice. It preserves most of the nutritional profile without the texture loss.
Do microgreens continue growing after harvest?
Cut microgreens stop growing at harvest. Living trays — still rooted in their grow medium — continue growing and can be harvested over 5–7 days at room temperature. Robby Ds Lil Greens offers living trays for this reason.
Why do my grocery store microgreens go bad so fast?
Grocery store microgreens are typically cut days before they reach the shelf. By the time you buy them, the 5–10 day window is already partially consumed. Locally delivered microgreens cut the same morning give you the full shelf life window.
