Your clover (do you know if the blend had white or red clover?) should survive, the oats (an annual) will be gone for all practical purposes. If the clover is still around, just mow the clover to a height of 6" a couple of times this summer. Not knowing your soil test,clover will usually benefit from an application oflow nitrogen fertilizer (0-10-10).

As far as expanding - experiment, that is half the fun. Since you only bowhunt, consider kieffer pears - a great draw for deer. Google to see if you have the proper soil, sun, moisture, hardiness zone, ripening time relative to your bowseason, etc...
