I have been gardening for years still have trouble with some plants i have started growing some exotic snap melons from india this year but my passion fruit vines are trying to take over the yard so I'm going to sell the extra vines.
I have had a similar thing happen to me but it wasn't the tomatoes that made the cage fall. My squash vine grew up the cage and pulled it down and my tomatoes left on the ground so right now i don't know what to do also.
