We finally got good broccoli growing in the raised garden after a warmer than normal fall. We know by trial and error that broccoli plants do not like summer like weather.  The raised garden seems to have the advantage of being weed free, along with not being washed out by heavy rains.  I might also add that with the mix of soil and the fact we had the PH checked, we seem to have a much better growing potential than just placing plants in an open garden and hoping for the best.
