Well Trish and Dave I have never heard of "hugelkultur". I plan to do some research and I will know by sundown. lol We are new to this site. My husband and I are in our first 10 months of sustaining our DIY Aquaponics system. We love it. We learn something new every day. We are retired so babysitting catfish and plants keeps us out of the bingo parlour. We plan to grow all year round. Of course, in Oklahoma you just never know about the weather. We can go from one extreme to the other in hours. The old saying in Oklahoma is "if you do not like the weather in Oklahoma, just hang around an hour or so cause it will change" Ronald and Sharon Love Dunlap, Old Green Shed
