who is winter sowing?
Posted February 14, 2025 by womeninlove in Gardening

What are you sowing this year? What are you most excited about?

I'm pretty excited to grow lots of seed I collected from my Mom's garden when I got to visit her this past summer for the first time in years (usually it is a winter holiday when we visit). Lots are a bit experimental, like clematis and panicle hydrangeas. Some have been very successful in the past, like bleeding heart. It was just a wonderful time walking around her garden and collecting the seeds. Planting seeds that have memories attached and growing flowers from them is a very special thing.

I've also had hybrid hellebore seeds in jugs since the summer (lid off in summer obviously) and I hope they germinate in the spring.

I wish we didn't have our privacy issues here because I'd love to do a seed swap.

Thank you for reminding me to do this! I have some large five gallon water jugs that I used last winter (made the tops removable). Last year I planted vervain, hairy balls (lol) milkweed, rudbeckia, and sea holly this way.

You've inspired me to start brainstorming perennial varieties to try this year.

Here's a collection of winter sow perennials from Select Seeds (woman-owned, pretty sure) for anyone else who is interested. I also like Prairie Moon Nursery.

You're welcome! I have about 70 jugs going this year. I might have gone a bit overboard.

Select Seeds is a great source and very pretty seed packets. They're fantastic for browsing to find new interesting things to grow. I also like Swallowtail Seeds, very high quality, but no fun seed packets.

I did sea holly a few years ago and it bloomed the second year for me, but I have a lot of shade so it didn't want to stand up. I'm trying butterfly weed, which is a type of milkweed, this year.

I always wonder why people grow the "hairy balls"? Are they cut flowers?

The seed balloons of hairy balls milkweed can be used for cut flowers. It was fascinating to watch all the different bugs and pollinators that made use of that plant. It also has pretty flowers.

I'm hoping my sea holly flowers this year, since it did nothing last year. I've tried growing butterfly weed from seed twice but both times they failed to thrive (possibly not enough sun or fertility where I placed them).

I am browsing Swallowtail Seeds now, thanks for the tip.

Interesting! I had never seen the flowers before and they are quite pretty.

I hope your sea holly blooms this year! They're so unique in the garden.

I don't know anything about winter sowing, but I see you shared a link and will look intl it 😊

I have bought sooo many flower seeds this year. Hope to do dried bouquets 😊 and sunflowers. I also ordered waaaay too many dahlias and bulbs, but I'll find a way to fit them into my garden. Lack of space isn't a problem, just lack of pots and prepared garden beds. I'll have my usual veggie garden, and hopefully I'll start using my greenhouse this summer.

It sounds wonderful, sowing seeds from your mum's garden ❤️ I hope you will be successful with all of them.

Thank you!

I relate to having too many seeds and plants. I have somewhat limited space (less than 1/3 acre) and did not properly prepare my beds before I started my current garden a few years ago. It meant over the last two years I've had to lift everything and redo the beds with compost. I still had fun in the original beds that were just sod turned over but it was a lot of work to redo them so I can see why you'd want to wait. A greenhouse would be amazing!

What are you planning to grow to dry?

I had a lot of luck with lunaria as a dried cut. I had maybe eight plants and I have enormous bouquets of them everywhere in my house now--even huge floor vases. They're biennial but were very rewarding and had pretty purple flowers before the seed pods, which I wasn't expecting because nobody talks about their flowers.

We're having a very wet and cold February so I'm holding off for another couple of months.

Cold and wet it great for the "winter sowing" method of starting your seeds in little recycled greenhouses outside:

Oooch, so that's how that works.

I had to google for pics of milk jugs. Think the method might be used with plastic water bottles, but the jugs are really better suited.

womeninlove [OP]February 15, 2025

You can use any plastic container that you can make those modifications to (drainage, closed but with holes for moisture to get in). I've used those plastic containers fresh spinach/greens come in and they work great.

This year, I finally managed to think of sowing chili in time (it's germinated now, but since I have no plant lamp, I am not sure how it will fare) Very excited about it.

What I also definitely want to try is beans, corn, spaghetti beans and perhaps okra. (Never tried to grow okra before, don't even know if I like the taste, but it's allegedly happy in high temperatures, which is what we increasingly get in summer. Normal beans don't set fruit because it's too damn hot! Spaghetti beans/Vigna sesquipedalis/yardlong bean did very well in the heat, but I'd started them too late so that they died before I could get a real harvest. This year I'm gonna try sow earlier.)

Gardening with climate change is a challenge!

I am trying to deal with it by using corn varieties bred by Carol Deppe (great garden book author!) that deal well with not being watered and varieties of corn that ripen in a short time, like Yucon Chief, to minimize the risks.

Probably I will try carrots again, though I never succeed. I had very limited success even with the famously hardy Swiss carrot variety used in the famed carrot cake. The slugs like them, too. 😬

Vegetables and beans are a whole different challenge! I don't know much about them because I grow ornamentals mainly, but I am dipping my toe into some hot peppers this year. Have you tried the "winter sowing" method with recycled milk jugs or other containers if you don't have an indoor growing system? That's what I do. I've seen people on YT who germinate their vegetables this way, but not sure what your zone is?

Carrots are particularly hard to grow! I grew them years ago and they'd seem to be doing ok but when I went to pull them they were undersized and tasted of nothing. We have so many slugs in my current garden that I couldn't think of it.

VestalVirginFebruary 15, 2025

I haven't tried that method yet - do you cut the jug in two, put the seed in and tape them back together, or how does that work? (We don't have plastic milk jugs here, it's either glass bottles or waterproofed cardboard, so I am not sure what exactly you are describing)

Weather is relatively warm here, so I might risk some winter sowing of ornamentals in pots outside. 🤔

As of yet, I had better success with ornamentals than veggies, but even with ornamentals, I suck at growing them from seed. Somehow, they wither and die at some point before they really get going. And that's if I manage to water regularly enough so that they germinate at all.

(Any advice on how to grow poppies? They grow wild in fields all the time, so realistically cannot be hard to grow, but I fail at it all the time. Perhaps trying to transplant them was the mistake those times where they did germinate? But, with the slugs, I don't dare direct seed.)

womeninlove [OP]February 15, 2025

You can use any plastic container for winter sowing (doesn't have to be a milk jug) as long as you can add drainage holes or slits to the bottom and it has a lid of some sort you can reattach but have some holes in to let in moisture and vent a little. I use leafy green containers like this when I have them, too, and they work really well.

The virtue of winter sowing is that it gives you the cold stratification period outside (less helpful if you're in a warm zone obviously) and also that they're in mini greenhouses, so the humidity tends to be just where you need it for seed germination. Since they're already growing outside you don't have to harden them off, so you get very healthy plants, typically.

I've grown oriental poppies before in winter sowing jugs. They germinate very well this way. I haven't had any luck direct seeding them because of slugs, as you said, though some people seem to succeed with it. I would just transplant them to a larger pot as soon as you can prick them out to grow on a bit before you put them in your garden (because slugs), trying not to disturb the roots too much. I never up-pot to more than a 4" pot for perennials--once they're bursting from a pot that size they want to be in the garden. I don't have great conditions for poppies because my garden is shaded and tends to be wet, so I've let them fall to the wayside, but if you have full sun and well draining soil you should be able to grow them.
