It's not a skill issue, it's a sunlight and temperature issue based on geographical science. There are hard limitations, including the length of the growing season. Canadians are also arrogant; most have never tasted the produce in California. Just look at what we call "Farmers Markets" here and compare to SF Bay Area and NYC Union Square Greenmarket. Even a trip to an American Whole Foods groceries section is scales off the eyes as to the quality differential.
Not the point. If you can grow then why are Canadian supermarket produce so awful compared to American tomatoes and raspberries? Think about that for a second and why that would be the case, if not for fundamental geographic limitations (the objective length of the growing season and the angle of sunlight). BC in particular is inferior and Montrealers moving here have made this exact complaint, it's not "just" me, sounds like you're in filter bubble.
Instead of rudely retorting 'it sounds like a you issue' why don't you not make such an arrogant assumption and suppose I had a deeper reason for saying what I did, that actually is based on experience and research rather than a superficial tour through Delta in peak summer. Don't argue back; just ask why.
Don't argue back? Way to promote intelligent discourse. I just disagree with you.. I've had lots of American produce and I can grow tomatoes just as good as those I've had in the US.
Comparing what's in a supermarket is also kind of a bad way to judge things, as both Canada and the US import a lot of items from each other or South America.
I'm not making an "arrogant assumption" I'm just refuting your broad and negative claim that our "land sucks." I shouldn't have to assume a bunch of nuance when you don't include any in your original comment. Is their limitations to growing in Canada/BC? Yes. I'm not growing citrus for a reason. But I disagree with your take, and I find it doubtful our geography is to blame for any poor performing tomatoes. Gardening/farming can be hard. My tomato year this year was poor but that was the fault of slugs.
Raspberries and tomatoes seem to grow fine on the boulevards despite rainforest soil being less than ideal. Otherwise Canada has extremely fertile land.
They are inferior goods and require warmth and sun, that's what they are limited by, the Canadian latitudes. Try American raspberries, it's a world apart.
Canada gets plenty of warmth and sun, and Raspberries do quite well in other provinces naturally. In Vancouver though, there's a few varieties that people plant and seem to flourish, but they don't propagate quite like the Himalayan Blackberries that seem to consume the city
