Why do salad greens wilt so fast?

Two failure modes: surface moisture left on washed leaves breeds bacteria and turns them slimy, while unwashed greens left loose in the crisper dehydrate and go limp. The fix for both is the same: wash, dry completely, and store airtight in the cold.

How to Keep Salad Greens Fresh for a Week (Not a Day)

The short answer: moisture control is the whole game. Greens rot when stored wet and wilt when stored dry and exposed. Wash them the day you buy them, dry them completely (this is the step everyone skips), and store them airtight in the coldest part of the fridge. Done right, greens stay crisp five to seven days instead of one or two.

Why greens die in your crisper

Two opposite failure modes, one cause:

Stored wet: surface water left on leaves is a bacterial playground. Wet leaves turn dark, slick, and slimy within a day or two. This is what kills pre-washed clamshell mixes fastest.
Stored dry and loose: leaves in an open bag or bare crisper drawer lose water to the fridge air, go limp, and never come back.

So the goal is precise: leaves that are dry on the surface, hydrated inside, and sealed away from circulating air.

The routine (10 minutes on shopping day)

1. Wash now, not later. Submerge greens in cold water, swish gently, and lift them out of the water so the grit sinks away instead of re-coating the leaves. Cold water also re-crisps slightly tired leaves.
2. Dry until actually dry. This decides everything. A salad spinner is the fastest route: spin until the lid stops throwing droplets. No spinner? Spread the leaves on a clean towel, roll it gently, and let it sit a few minutes. Damp is not dry.
3. Store airtight and cold. Airtight container, coldest shelf (back of the fridge, never the door). Drop a dry paper towel in to catch residual moisture. Swap it midweek if it feels damp.
4. Dress at the table. Salt and vinaigrette pull water out of leaves in minutes. Dress only what you're eating now.

The one-bowl version

This routine is exactly why the Jarelli Glass Salad Spinner ships with two lids. Wash and spin in the same vessel, then swap the spin lid for the airtight storage lid and put the whole glass bowl in the fridge. Wash, dry, and store collapse into one container, which is the difference between a routine you read about and one you actually do every week. The glass bowl also means you can see when you're running low.

Greens cheat sheet

Hardy greens (kale, romaine, cabbage)	Last longest: 7+ days washed, dried, airtight. Kale actually softens pleasantly after a day or two.
Medium (green leaf, red leaf, butter)	5-7 days with the full routine. The paper towel swap matters most here.
Delicate (spring mix, arugula, spinach)	3-5 days. Buy these closest to when you'll eat them and handle gently: bruised leaves rot first.
Fresh herbs (parsley, cilantro, mint)	Treat like flowers: trim stems, stand in a jar of water, loose bag over the top, in the fridge.

Common questions

Should you wash lettuce before storing it?

Yes, provided you dry it completely afterward. Pre-washed greens get eaten; unwashed greens get composted three weeks later. The only rule that matters: never store wet greens.

How long do washed greens last in the fridge?

Washed and thoroughly dried, in an airtight container in a cold spot: five to seven days for most lettuces. The same greens stored wet: one to two days.

Can you revive wilted lettuce?

Often, yes. Soak limp (not slimy) leaves in ice water for 15-30 minutes and they'll re-absorb water and re-crisp. Slimy or dark leaves are gone; discard them before they spread.
