Rock-hard kiwis? Don't toss them because ripening them at home is easier than you think, and OMG, the payoff is so delicious. In this post, I'll show you how to ripen kiwis on the counter, how to speed up the process, and whether you can still harvest kiwis after frost.

The first thing we saw? A canopy of giant velvety leaves overhead. Wait... is that... a kiwi tree?! Right above us?!
We stopped in our tracks, completely surprised. I mean, it was November. In Germany. Cold, wintry, definitely not the season you'd expect to stumble across a tree full of kiwis. But there they were: dozens (maybe hundreds?) of little brown fruits just hanging there like a scene from a storybook.
Honestly, the dreamiest home entrance ever!
Our next thought? If the apartment is even half as magical as this entryway, we're in. Spoiler: it totally was. We moved in within a month, and five years later... still here, still swooning.
Every year, that enchanting kiwi vine gets me all over again. No matter how hectic life gets, something about walking home under those heart-shaped leaves and jungle-like branches just melts the stress away.
Why Kiwi Trees Smell (Yes, Really)
Yes, we love our kiwi tree... even when it turns into a total stinker. And I mean STINKER with a capital S! We're not talking about a subtle, earthy aroma here. Nooope, this is an awful stench. I truly couldn't believe something so beautiful could smell that terrible.
On hot, humid days, the tree emits a smell that... well, let's just say it's funky. Like, "why does it smell like a swampy gym sock?" funky. At first, we blamed the pretty kiwi flowers (they look like delicate white anemones and camellias) but it turned out, they're innocent. The flowers barely smell at all, they give off just a faint, lily-of-the-valley sweetness if anything. A quick online search revealed the real culprit: the leaves! Apparently, during the flowering period, they let loose with that nose-wrinkling aroma.
But, you know, it only lasts a few days a year, and the rest of the time is pure fairytale vibes under those lush, leafy branches. So: Worth it.
Except... there's just one thing that always gets me: those gorgeous kiwis, dangling there like a promise, never ripen. Every November, they're small, rock-hard, and inedible (of course, I taste-tested). So close and yet so far! Eventually, they just drop to the ground.
Oof. Heartbreaking!
How to Ripen Kiwis
A few weeks ago, a lightbulb went off: Wait... some fruit ripen indoors! Bananas? Leave them out, and they magically go from green and hard to soft, sweet, and snackable. Persimmons - tropical fruits just like bananas and kiwis - transform from bitter little tooth-breakers to pudding-soft flavor bombs, sugary sweet. So why not kiwis?
I decided to run an experiment. I plucked five tiny kiwis from our tree and set them on the dining table. Every day, I gave them a little squeeze to check for softness. I didn't have high hopes. I mean, these weren't just unripe, they were barely grown (see picture below for size comparison between store-bought and tree-picked).
And then - surprise! - a few days in, one of the kiwis was... soft. Like, really soft. Was it rotten? Only one way to find out. I peeled it, gave it a cautious sniff, and took a tiny bite. WOOAAAH! Super sweet. Ridiculously delicious. Hands down, the sweetest kiwi I've ever tasted.
Gradually, the other four kiwis softened too, with the smaller ones ripening first. Naturally, I went on a kiwi-picking spree. I had to get them all from the tree! (Well, at least all within my reach, which I cleverly extended with the help of my 1.90m-tall partner.) Over the next few weeks, we enjoyed a steady stream of ripened kiwis, with two or three ready to eat each day.
What a green goldmine! This really is the apartment of our dreams.
Next year, I'll be prepared. Lesson learned: kiwis do ripen in winter-cold countries. Just pick them from the tree and let them hang out in your warm, cozy living room. It is really that easy! In fact, kiwis are meant to be harvested unripe. It might take a couple of days and up to 2 weeks for them to turn soft and sweet (depending on the temperature).
How to Ripen Kiwis Faster
Place the kiwis in a plastic bag with apples or bananas, and leave a bit of ventilation (air should get inside). Then watch as your kiwis turn soft and sweet in no time!
Can You Pick Kiwis After Frost?
OK, so you can pick them when they're still firm and unripe! But what if the frost has already arrived? Is it still okay to harvest them after a few frosty days or nights?
Kiwis can handle light frost, and a slight chill might even help kick-start the ripening process. But heavy or prolonged frost? That's another story, it can damage the fruit's cells and you get mushy, spoiled kiwis.
Bottom line: One or two light frost nights won't harm your kiwis. On the contrary, they'll be just fine, simply pick them and let them ripen indoors. But if you leave them hanging on the tree for months of frosty weather, the quality goes downhill. I find that the fruit starts tasting off: slightly fermented and not in a good way. It loses that fresh, true sweetness and turns into something... oddly sweet, but just wrong.
FAQs
You'll notice it when the fruit starts to give slightly under gentle pressure. Once a kiwi isn't rock-hard anymore, it's on its way. I usually wait another 2-3 days until it feels noticeably softer before eating.
Anywhere from a few days to several weeks. Don't give up too soon, some kiwis still soften after 3-4 weeks. Ripening time depends on many factors: when the kiwis were picked, whether they experienced frost, how warm your home is, and whether they're stored near apples or bananas.
Here in Germany, I've found the best time is shortly before the first frost or 2-3 days after it, usually in November. By then, the kiwis have stopped growing, and a little frost can actually help them ripen better indoors later on.
Yes - speaking from experience. One year, I picked a basket full of kiwis in mid-October, well before the first frost. Even after 6-7 weeks indoors, they softened only slightly and never became truly sweet. The batch I picked later, in mid-November, was infinitely better.
Yes. A few light frosty nights can even help kick-start the ripening process. Just don't wait too long as prolonged frost can damage the fruit.
Place them next to apples or bananas. These fruits release ethylene gas, which helps speed up the ripening process.
✨ Here's to gorgeous, green, sweet kiwis, the wonder fruit you can harvest unripe, let ripen indoors, and even pick after the first frost. So forgiving, so delicious. Yum!
