Did I mention pond plants?

Cut back your tropical pond plants now.  If you plan to overwinter them, bring them in the garage or the greenhouse.  Most of them will do fine if not frozen solid. If you have anacharis and your pond will freeze solid, bring it in too and put it in a washtub in the garage. (Garage getting crowded?)  Put your goldfish in there too if your pond is not below your frost line

Cut back your hardy plants as well. I cut mine back to about 3". The pond will look dreadful all winter, but the plants will come back green and healthy next spring when the plants put out new growth.

To make the fall pond into something besides a gray hole full of water, add some mums around the edge for fall color.  Put a few painted cinder blocks in the pond to raise decorations out of the water and put some Halloween decorations on top.  Or a few more pots of mums.
