I bought a 3/4" concrete bit - 12' long. The wife will work on this idea this weekend. We have got to try everything we can, the OKC mayor announced mandatory water rationing this week, in the middle of winter! I have lived in OK for over 30 years now and they have never had to do this before. Sure sometimes in July or August they will limit the amount of watering you can do on your lawns, but we have had so little rain this past year they are having to take more radical steps. Our 2 city lakes that are used as water sources for drinking water are down about 50%.
I will dig several more woody (HK) beds this winter, mine are the in ground type, I have a backhoe so it's pretty easy. Lots of partially decayed wood to fill them up with. We round up several pickup loads of oak leaves from along side the curbs in the fall and early winter once others get them raked up. We mix in a couple bags of leaves in with the wood, layering in soil as we fill it in. We started 3 compost large piles 2 weeks ago, started with mulched oak leaves, seasoned horse manure, adding bags of hay and rabbit droppings, egg shells and anything I can get my hands on to throw in it. Not too many kitchen scraps, the rabbits get all of that stuff. Guess it ends up there anyway after the rabbit's have processed it for me.
We use the shredded oak leaves as ground / mulch cover in and around the garden to help keep the moisture in. I don't have a lot of background in gardening, but learning fast. I teamed up with a partner who has run a 2 acre market garden for the past 7 years, his experience and expertise will help get our current 60 acre project off the ground much quicker. We are currently working with 5 acres that is the garden, focusing on 2 of that for now with all the manure we can haul in. The other 3 are being planted with cover crops. We are having to till the soil a lot more than we would like to, but having to do so to kill out the weeds. It's a big undertaking, but we have the equipment and several families that are helping out on the project.
