RE: when is to late
NVR
Its already too late for a fall clover attractant plot in most areas.
Its not to late to PLANT - but its to late if you plan to hunt over it. Unless the soil is exceptional - clover can take 8-10 weeks to establish well enough to support several deer.
Fall planting ( Late August ) with a cereal grain nurse crop is a good option. The Grain is THIS FALL'S attractant - and the clover comes in strong the next couple years after.
