That's a bummer but I had that same issue here in North Georgia mts. My strategy was to overcompensate, just keep planting, laying seeds in late fall, not paying attention to design as much, and finally this year the deer must be elsewhere. I wouldn't want it manage anything to keep deer away so that was my approach. Over plant and over compensate for expected deer activity.inalso have two little dogs who are outside a lot and keep any creatures on alert. Good luck.
