RE: help please!
Rarely will the biggest buck eat in the best little plot - sometimes not even the best really big plot - at least not in the daylight hours.
Big bucks tend to move around alot come hunting season. The best thing you can do is make your area attractive to the Female Deer - and keep the humaninterference to a minimum, "your buck" has already shown that for some reason he likes the area - the does will keep him coming around in October/November.
If you feel you need to plant to keep the does around, try Not Hunting the plot - make it a sanctuary of sorts - hunt the trails to and from - it will not scare off a mature buck as quickly as he scent checks the plot come October.
