The title says it all. Can squash and other cucurbits survive winter?
I have been taking the seeds from any squash or pumpkin and burying them under our woodchip mulch. Now I'm wondering if there's actually any point in doing so. I am in zone 5b so our winters are pretty cold and they may kill the seeds...
Do you have experience with this? Do you collect cucurbit seeds or do you let them self-seed?
In NC (zone 7) we would have volunteers of pumpkins and cukes (and many other things) pop up in random places around the yard after the squirrels got through with the fruits.... so they can certainly take freezing. below 0F, I'm not sure.

Im curious how you overwintered the tomatoes? Row covers or greenhouse or something?
Brenda, that's why i'm slowly making a seed stock of pumpkins and squashes which are edible and do not cross pollinate. Even not with other edible. One of them right now i have is fig leaf pumpkin (http://en.wikipedia.org/wiki/Cucurbita_ficifolia). This one do not cross pollinate with any other. Pumpkins and squashes really do like to pollinate. If edible cross pollinate with other edible it might be good. But if it cross pollinate with ornamentals which are bitter, then fruits are not good anymore.
Rob, i have not overwintered the whole tomato plant. I was referring to the question in the title. So, tomato fruits easily stay out over winter on ground, where i want them to grow next year. Seeds are then viable and they germinate in spring.
gotcha, so you just put the whole tomato where you want it to grow next year. I assume if its heirloom it will be just as good as the prior year? Have you ever experimented with the genetic evolution of the plants to achieve a certain result? For example, saving seeds from the earliest ripening fruit to develop a whole crop of early ripening fruits, or cold hardy etc.?
Yes, whole tomato where i want it to grow next year. Do not cover them with mulch. Do that in spring. I have done this the first time last year from 2009-10 season. As genetics go, I don't go in such details. I just save healthy fruits and put them on ground for next year. And i save them from first ones to latest ones. Most important point for me is to grow seeds from my own climate, soil etc. So year after year i'm growing new seeds which were growing on my place.
Great book called 'SEed to Seed' by Suzanne Ashworth discusses the sexual habits of a wide range of common and uncommon annuals by species.
Tomato (Lycopersicon lycopersicum) - flower structure varies among varieties - many modern varieties have retracted styles that limit cross breeding. Double blossomed varieties of early beefstake have exposed stigma and are more succeptable to crossing. Other species like L. pimpinellifolium (current tomato) cross more readily.
Most squash come from 3 species: Cucurbita pepo (acorn, crookneck, zucs), C. moschata (butternunt..), and C. maxima (hubbard, turban, pumpkin...). Cucumis sativus (includes a variety of cucs), Each species is as promiscuous as the bees that move the pollen, but ONLY WITH other varieties within species. A cross can produce unpredictable results, but you could grow a butternut, a pumpkin, and an acorn next to eachother and have true seed unless your bees are visiting other varieties within species...
Also in zone 5b here.
We get -13F as our avg. lowest temp several times each winter.
We get volunteer squash every year. From loose seeds, not rotted fruit, though most are probably buried. We've had volunteer squash, beans, peas, potatoes, lettuce, kale, onions, tomatoes and something that's either garden huckleberry (likely) or tomatillo. (Can't quite tell which at this point. Possibly some of both.) Some I'm sure are from compost (we bury it raw) or visiting critters, while others are from "escapee" seeds, lost while planting or washed away. And others yet from plants gone to seed. Hard to tell which is which sometimes, though I'm positive the petunias in my vegetable garden came in with some visiting critter or other.
Lots of other volunteers, too, but not really vegetables.
in michigan i have found that a discarded fruit will reseed in spring, but it is intact inside the fruit that rots over winter and in spring is ready to fruit..as far as planting the seed, directly I doubt it. The seed would likely sprout way too early and then the plant would die over winter.
often if you have a ..say winter squash..that has gone bad and you toss it out...you quite often will get volunteers from it the following spring..but that is intact, not planted.
Bloom where you are planted.
Hi, yes, they can unexpectedly. I had some squash seeds come up on their own in the garden when they didn't grow last year, though I was puzzled where they'd disappeared... Unfortunately they didn't make it this spring because of frosts.
Ok, the difinitive from the old farmers, mother and father.
Mom is more of the fruit and veg farmer. She says plainly that you should be getting volonters. But doubtfull if it was in a compost pile. The drying of the freeze helps the seeds survive. A wet fall will probabbly destroy the seeds in the Mellon or ground.
The viability will depend on the background of the seed. The old/heirloom varieties will be far more likely to make it. She says she has seldom had a hybrid do well. Even when we were kids, the old ladies had cross breed fruit and veg that was particular to that garden and local area. Flowers too.
I have never met a stranger, I have met some strange ones.
Not looking good. I think this might be the end. Wait! Is that a tiny ad?
