one of the articles says you need like 40 tomato plants (another says 5-8 which seems more accurate) and one says like 10 cucumbers, etc. but we usually always grow at least 10 or 15 tomatoes and end up with waaaaaaaaaayyyyyyyyy more tomatoes than we even know what to do with.
If we had 40, we would be drowning in them and they would never get eaten. Unless maybe we canned or made salsa or pasta sauce or something with them but even then probably still not.
And we only had 3 cucumber plants and had more cucumbers than we know what to do with. And was actually mostly just one plant providing most of them.
