Thanks so much for all these awesome replies. My primary goal is not to make money. The truth is that I had been gardening for a number of years in a rented first-floor apartment when I was displaced by a new owner. I had completely transformed the back courtyard (with the original landlord's permission) into a shared garden (for the occupants of the triplex). It practically destroyed me because I had become so rooted to that spot, and I spent a ton of time in the garden designing new beds, planting all kinds of different things. I just fell in love with cultivating. I am also an oil painter and I felt that the garden was my canvas in the summer. Now I am in an apartment in Montreal with no access to outdoors, not even a balcony. That is why I have decided to move to the only area of Quebec where I can afford to buy a good house on a decent piece of land. My priority is to be able to cultivate something in the soil. I don't feel that I can live without doing that.
Someone above mentioned that their first move wouldn't be to truck in soil. I'm wondering why not? The soil would be coming from a local source that I have already found. It's not recycled soil. It's likely sourced in the boreal forest close to the coast.
I really like the idea of a fast-growing hedge I could grow as a windbreak. I have started a data-base for potential plants and I will research Eleagnus Umbellara and add it.
Another idea is to start plants from seed (starting indoors and then transferring out, like to a greenhouse) that I could sell to people in the region who want to garden with perennial plants that are suited to the area. The closest garden centre is about 1.5 hours away to the west of my village. About an hour away to the east is a very small town which I don't think has any garden centre. The population in the area is very small even though it's a very large area. Like only a few thousand. So certainly I am not thinking that I could make a living selling plants, but it would be a great hobby and I figure I could recoup my costs at least. And it would be a wonderful way to connect with other people from the area!
There are a few edible vegetables that grow wild along the coast in the area. Honkenya peploides (sea chickweed), Lathyrus japonicus (sea pea) and Ligusticum scoticum (sea lovage, also called Scot's lovage). So I think I will be able to cultivate those. And of course lots of different berries can be grown in the area. I love the idea of growing for the birds. There is a series of islands close by that serve as a bird sanctuary. It would be so awesome to see how many birds I could attract!
And yes lots of seaweed for fertilizer. And there is a type of very small fish called capelin that rolls in by the millions at the end of May, early June. You can go to the shore and just scoop them up in nets. I know people use them for garden fertilizer, although I'm not sure exactly what the best way would be to harvest a large quantity to build good soil. I thought if I trucked in topsoil I could start some sort of a compost bed with the soil and capelin and cuttings from whatever is growing around there. I will also be able to easily haul stuff out of the boreal forest because most of the surrounding area is all public land.
And yes, WHOOFER volunteers is an awesome idea!
