Plant nursery winter ideas

I try to start a plant nurery coop. I have some interested people together. There is a art coop round here which works in the way that they share the rent etc and the work and everyone gets the profit from their own sales.
So far so good. I know that plants sell extremely bad in winter. I don't graft fruit trees and Christmas is in summer here.
I search for ideas what to sell in winter! Any input welcome!

Sprout citrus trees?

you mean seedlings?

What's your winter like?

We are in cool climate. That means it can go down to -5C at night. What I learned from market stalls is that plants do not sell very well in winter. Yes you can grow stuff in winter and you can garden, but most people don't.
In the Northern hemisphere you can offer Christmals decorations and the like, but not here.

sorry, I'm unclear on what you are asking. Do you want ideas on what plants to sell in the winter from the nursery? Or ideas on what to sell in winter instead of plants?

Plants I would buy in the winter here (which is somewhat colder than you) are coriander, parsley, corn salad. Easy to grow, low maintenance plants that provide nourishment at that time of year. You could market them as such.

Non-plant things to sell: books, workshops, garden consults, story telling, locally made crafts.

Is there a reason you want to sell things in the winter? Might be better to make income at other times of the year and use the winter time to build composts or clean and tidy infrastrucuture, or rest.

Where do you live? What is your community like? Will buyers be locals or people passing through? Is there a building at the nursery or is it all outside? etc

Something along the corn salad line... perennial edibles for example. At the moment I am actually selling at markets.
I think this is the right direction greens you need in winter like alexanders for example.

Here in the U.S., much of the fresh stuff we buy in winter is either imported from south of the border, or it is grown in hothouses. Hothouses are not cheap to set up, or operate, but it does give you the ability to grow things that people cannot otherwise easily find. Selling plants in wintertime is slow here as well. People are just not into the mindset of growing things until things begin to warm up in the spring.

Perhaps, some lovely houseplants would catch people's attention.

I have some old window panes and will make some hotbeds with manure... And I have got a connection further down with a warmet climate thankfully, I might be able to grow some houseplants.
