I’m appalled at how much my wife and I end up letting produce sit around for too long and losing it. It’s not half the produce we buy, I’d say, but it’s a lot. Sometimes the stuff goes bad way sooner than we thought it would, sometimes we forget we have it, sometimes we’re too lazy to make that dish we thought would be so awesome in time.
Our compost bin reaps the rewards.
You?
The “crisper” in the fridge is known as the “rotter” at my house.
I picked “I refuse to buy produce” precisely because I always waste so much of it.
“Less than half” is the lowest possible option. Really?!?
I thought I was bad because I probably throw out a cucumber or some lettuce once a week or so. That’s maybe 5% of the produce I buy. I guess I’m in the minority.
I’ve found the trick to produce is that you need to buy no more than 2-3 days worth at a time. If you’re buying it once every week or two, yeah, it goes bad. Buy what you’re going to eat in the next few days, and plan on buying it at least twice a week.
I buy it for cooking projects that somehow never get started.
There’s always “none.”
But anyway in my opinion too many poll options dilutes the poll.
Grocery stores: we have a running list, impulse buys are not nonexistent but kept to a minimum. We can mostly go through what’s in our veggie drawer and root bin before it goes soft/black/dried out. There’s certainly the occasional “Oh, hey, I totally forgot was in here.” “Really? We had some ? Is it still any good?” "Well… " but for the most part, we’re okay.
Farmer’s Market: oh, Lawdy. All those piles of lovely, healthy, farm-fresh veggies. We definitely shop with our eyes when we go … which is why we try to keep those trips to a minimum. Every time, we get home, pile all the fruits and vegetables on the counter, and then groan a little. Then make a big bowl of gazpacho! 
We’re usually pretty good at my house, with one exception – if something gets pushed to the back of the fridge, my wife will never see it again until it’s too late.
I do almost all the cooking and food shopping for the family. I usually have a weekly menu roughed out before I go to the store; I shop from a list and buy only the foods I plan on cooking. I have thrown out produce 2 or 3 times so far this year.
You poll is deficient. It needs one more option between less than half and never. Obviously I waste almost nothing but jeez I won’t eat produce that’s gone bad.
I eat fresh vegetables almost every day and buy locally whenever possible.
I’m terrible at it. I cook and shop, so it’s all my fault. There’s only two of us, so that’s part of it, but damn - I try and try and try, but I throw a lot out.
It depends on what it is. Since as of right now I don’t do much of the shopping then I would say half goes to waste. Especially the veggies. I think when I have to start shopping for myself then it will get a bit better. Mostly because I’ll not be buying it. 
I’ve made adaptations to my shopping to reduce my produce wastage - green peppers get chopped up, aliquoted, and frozen as soon as I buy them. I buy bagged salad because I know I won’t wash it and eat it otherwise. I buy limited amounts of produce and try to remember to prepare and eat it. And the compost heap still gets fed occasionally, but I do try to limit it.
I subscribe to a CSA membership so I get a big box of random vegetables each week for a good portion of the year (starts next week!). Last year I just got waaaay too much lettuce, and radishes galore later in the season. Plus all the carrots and beets and turnips and so on came with the greens on top.
I’ve solved the issue by buying two pet rabbits.
Here is the trick: frozen veggies. Peas and carrots freeze wonderfully, and canned potatoes taste just as good as the real thing - though you have a different texture, so they can’t be used, say, for mashed potatoes.
But I almost never throw out veggies now.
Pretty much my approach. In addition to not going bad, I think they are picked when mature.
Corn, peas, carrots, brussel sprouts, and expensive broccoli are fine frozen. Spinach is only okay frozen but fresh spinach goes bad before you get it home.
Sprouts and greens must be used the day they are bought. Must.
Must.
Potatoes and carrots and mushrooms do not go bad. They shrivel up a bit, but never get moldy. (Unless you leave them in a plastic bag in a dark warm enclosed space - that was scary.)
However, I must argue that composted vegetables are not wasted. A healthy compost needs fresh material.
I don’t consider it wasted if goes to either the chickens, the sheep and goat, or the compost bin. But we eat more than half of what I buy. We give away bushels of stuff in the summer from the garden; I really only buy lettuce then.
We’ve gotten much better at it lately. When we decided to do a little life-style changing and eat healthier, we started doing a lot more meal planning that used up the left-overs more effectively. Not only has this saved us money by cutting down wastage, it has also cut down my waistage. I’m down 8 pounds since the end of April.
I’m not a fan of frozen vegetables, and I live alone, so I probably end up throwing away about 1/4 of the produce I buy. I’ve been eating tons more raw vegetables lately, though, so that number has gone way down. I live in a condo, so I’m pretty sure I don’t need compost, but if someone can make a case for it I’ll listen.
I wish there was a reply between “less than half” and “never waste.” I waste very little, but it happens every now and then. I didn’t answer the poll since my answer would be less than 10%.
I’m a big time meal planner, I buy the stuff I need to make specific recipes, then I cook the meals I plan. If I have leftover produce, I plan meals around the leftover produce. I make two trips to the grocery store a week (Sunday for Monday - Friday lunch, and Friday for Friday night through the weekend).
Sometimes, stuff goes bad before I can get to it for whatever reason, but it really doesn’t happen very often.
I don’t let myself buy produce anymore because it always ends up badly. I’m single, and while I have a roommate (who happens to be a vegetarian), he always eats out.
The only thing we keep in stock is bananas. Neither of us is turned off by brown bananas, so we always have them on hand. I try to buy a lot of them, and buy unripe ones. On occasion I buy myself a bag of baby carrots, which have an incredible shelf life.
I only shop every two weeks or so, so there’s no way to buy fresh produce and keep it around unless I consume it all quickly. And I never do. So I just don’t buy it.
I do keep frozen veggies on hand. I also keep V8 juice on hand. If I’m out anywhere, I try to eat veggies because I know I won’t be getting them at home.
