Yeah, tomatoes are the queens of summer veg, but I get lots if them outside.
I have a pepper plant I'm trying to overwinter in my basement, maybe I should give it a space in the summer greenhouse?
I was considering sweet potatoes, since they tend to need a lot of days.
The peppers are something we eat, that performed best at the end of the season, seem to do better in containers and can live multiple years, so they may be the winners.
Any ideas for vines?
Climbing annuals that crave long hot summers?
Other than tomatoes, of course!
Well, cucumbers come to mind for climbing vines. They of course do well during a long, hot summer so it would be interesting to see how they would do in a greenhouse.
Another thought: Though I have never actually tried it, I like the ideal of a "salsa garden"--Tomatoes, peppers, onions, etc. If you like the idea, maybe these would be good crops to continue growing in a greenhouse.
And since you like vines, might a sweet potato work in a greenhouse? I don't know how much space you have, but sweet potatoes are delicious, grow on vines and just love hot weather. I would think that if you can get tomatoes and peppers to grow in a greenhouse, a sweet potato would do well.
How about green beans? Maybe you could train some pole beans to give you a continuous crop over the winter.
Maybe eggplant? My trouble with eggplant is that it seems to attract just about every pest known to Man. But in a greenhouse, maybe these pests would be diminished/reduced/controlled?
I don't really know how much space you have in your greenhouse and these crops might take up too much space is space is at a premium. But I thought they might be some good options.
