When growing tomatoes, cucumbers, or other fruiting vines in raised beds, you really need strong supports. Those flimsy hoop things at the garden center are useless for plants in good soil.
Trellises are the best option in most cases:
Though with small vines or vines that are planted late in the season, cages will do.
Cages work for big plants too, though I find them harder to work with, especially when harvesting.
Or have fun mixing and matching supports you happen to have in the garden shed!
(This is a rough draft post I’m putting up to answer a question. Stay tuned for the updated version.)
