Do you have any bees? Mine always have bees on them and have lots of fruit, especially now with the cooler weather. I scattered seeds in the garden in April (having heard they grow like weeds) and got like 8 tall plants. Also, I read on the variety description that many other tomatillos can't tolerate the weather and soil in the Midwest where I am, but this kind was developed in (I think) Virginia so it thrives.
