They love the sun, but don't shade other plants. They're ripe when the skins are papery and dry. Be ready to hunt around the ground for them as they fall from the plant when ripe. I like to go out every other day, which, as it happens, is also good timing for my tomatoes and cucumbers.
Their tart, even lemony flavor combines well with pepper, cilantro and avocado. Don't be alarmed by their sticky skins underneath the dry husks, that's just another of their charming characteristics.
