Karen, I think your practice about using the polymers mainly for late season stuff is good advice--at least for someone like me, who tends to use them with a too-heavy hand. I tipped out a jug of WS alyssum seedlings yesterday because they looked "off" and I saw these giant gel "blobs" that were probably keeping the soil too wet, with all the rain we've had, to the point where the seedlings were getting too much moisture. Going to remember that as well, next year!
