We have a tomatillo plant in one of our raised beds that's just going nuts; flowers all over it and yet, no little tomatillos. Chatting with my neighbor who actually grew up in rural Montana and knows his way around a vegetable patch, I come to find out that you have to plant two because they don't self pollinate.
And that means no tomatillos for us this year. Why don't they sell them in flats of two???
