How Long Do Microgreens Actually Stay Fresh

Short answer: 5-7 days, refrigerated, if you store them right. Longer answer: it depends a bit on what you do between "when microgreens have arrived" and "when they get eaten," so let's actually walk through it.

Why the range, not an exact number?

Freshness isn't a light switch, it's more of a slow fade. A few things affect exactly where you land in that 5-7 day window: how quickly you refrigerate after pickup or delivery, how much moisture is sitting in the box, and honestly, which variety you've got, some hold up a little longer than others.

That's actually the whole reason we stamp a harvest date right on the box. On our end, once we harvest, your box goes straight into our fridge and stays there until it's picked up or delivered so the clock that actually matters is the one that starts once it reaches you, not before. Instead of guessing how old your greens are, just check the date and count forward.

The two things that actually determine how long yours last

1. Refrigerate them right away. Sounds obvious, but this is the single biggest factor. Microgreens left out at room temperature start losing quality within hours, not days. The moment your box arrives, fridge first, everything else second.

2. Don't rinse before storing. This one trips people up. It feels like the "clean" thing to do, but extra moisture sitting in the box is exactly what speeds up wilting and mold. Rinse right before you eat them, not the moment they arrive.

How to tell if yours are past their best

You'll generally notice it before it becomes a food safety issue — the leaves go from crisp to soft, color starts to dull, and you might see a bit of sliminess if they've gone too long. If something smells off or looks visibly slimy, that's your sign to toss it, same as you would with any fresh vegetable.

Getting the most out of your 5-7 days

• Keep the box closed in the fridge, ideally in the crisper drawer
• Check your harvest date stamp so you're not guessing
• Use the boldest-flavored varieties (like Zesty Radish or Spicy Fusion) earlier in the week if you're worried about timing, a little wilt matters less when the flavor's already intense.

The bottom line

5-7 days, refrigerated, unrinsed until use. We keep your box cold right up until it's in your hands, check the harvest date, trust your eyes and nose, and you'll get the full window every time.
