When and how to harvest tuna?
My fruiting cacti have red fruit now. I have given them a little tug but they seem to be holding on. I have two different cultivars. The one that is supposed to ripen in Sept is turning a dark red. Is there a way to tell if they are ripe by if they fall off easily?
Also, what do I do with them once picked? I believe I have to peel them. Any dangers to worry about?
