Cover crop of oats and rye will be a huge plus IMO. Something green in the plot for the deer to eat this fall while cloverlings get established, oats will die with frost, but rye will continue to grow and be the first green the deer have next spring. Then as the rye takes off in spring, it will further protect your young clover from browse pressure until it can withstand it on it's own. Mow or spray the rye with cleth to terminate it and release the clover. Or you could just let the rye mature and drop seed to get a volunteer crop of free rye the next summer, but that is another story.
