We do the Food Plots year round,they will keep the Deer in Your areas and hold them there because they know they have a good food source at all times.We also put out salt blocks,mineral licks and one of the best attractants I have used is the Arm & Hammer salt licks.
You take a box of the Arm & Hammer Super Washing Soda,break up the ground in a 3' X 3' circle breaking the dirt up fine with a shovel,pour about 1/2 the A & H onto the dirt mixing it up then take about 15-20 lbs of rock salt and spread it over the dirt then take the rest of the A & H and spread it over the salt...after time the rain will wash it into the ground and the Deer will hit it year round.You can refresh it every 3 or 4 months and even add a little mineral to it if allowed in Your State?I like putting some Lucky Buck in mine because it has a good amount of different mineral to help the Bucks with Antler Growth.
