I spent most of last year mending the supports for my Purple Sprouting Broccoli. They’re really heavy plants and the supports did not withstand the wind. I was quite proud of my attempts this year and the support seemed sturdy!... However, woke up this morning to toppled plants and the cane support almost lying flat. I’m using 3 canes per plant... any tips on making a sturdier support for these heavy plants! My patch is in the front garden and we’re on a hill... so wind can be an issue!
