Is it true that you should not place the feeder close to spawning areas?

If the best place to put your feeder (I have to hang mine from a tree) is not necessarily the best water, should one consider adding rocks, trees, etc. under the feeder?

If this is the case what would someone recommend?

BG, HBG, GSF, CC and maybe some minnows (if any were lucky enough to make it) are what currently eat my feed, just in case this makes a difference.

I plan to put mine back up tomorrow so that is why I thought I would ask.

Thanks
