Good info. Thanks to all. Rainshadow, any more info on what brand and size of your electric? PM me if you want.

I'd rather chop up a little every week or few rather than save up, but may do a big pile all at once for the larger branches.

FWIW we want the compost, which is excellent, not just trying to get rid of stuff. My DIL grows flowers etc. by the thousands, constantly planting so there is always fresh blooms from early spring to late Fall, plus the big food garden. Finely chopped up plant material composts FAST, and the wood chips balance the process, keep it "cooking".
