Looking for sustainable bed concepts I found keyhole gardens, I really like that your compost and bed is alll in one place as well as it seems to be fairly water concerving practice... anyone has one? Experience to share? Might be good for det and dwarf tomatoes?

I have seen discussions about them on the Vegetable Gardening, Frugal Gardening, Texas Gardening, Experimental Gardening forums and several others as well over the past year so those folks would have experiences to relate. The search will pull them up for you.

Dave, thanks!
I will browse some more but direct name brought very few results so far and I do not visit many forums, just tomato one.
I am always on lookout for lazy gardener ideas LOL

I have seen videos of this.
It is an African home gardening concept.
As you trim, prune, and weed you put the stuff in the compost right next to your bed.
It is an interesting way of gardening and composting to me.

RE: keyhole gardens

I had no clue what :"keyhole gardens" were until I opened this thread. It turned out that it is a concept that has been on my wish list for a few years since the Garden Tower came out (not to confuse with the rip-off Tower Garden), which is in some respects is a supercharged version of the keyhole gardens right here in the USA, undertaken by home gardeners in every US state.

The Garden Tower system dumps all kitchen and vegetable waste into a central worm cylinder, same sort of thing as the keyhole. The worms accelerate the composting and enhance the nutritional value, so it can properly be called a vermicomposting system which is not as passive, making it a cleaner thing IMO as if you don't emphasize the role of the worms and just have fermentation and rotting going on from microorganisms.

The worms then move from the central cylinder aerating and carrying finished poopy fertilizer throughout the rest of the bed pretty fast since they are young and restless. In the plastic small design Garden Tower there is no need to clear a path to walk to the compost tube since the whole thing is small enough to reach.

But I can easily see a tailored setup any home gardener could make if they want to grow larger plants like tomatoes, where a wider garden bed setup would do for greens. For that, I had thought about a central tube that doubled as a support spine from which the vines could be hung. One small version might be to half bury a liner or even do it in a recessed garbage can if you wanted to keep the nutrients from leaching down and put 4-6 tomato plants in each one each with its own vermicomposting factory core, and maybe use it as a cookie cutter design if it gave good results. Something like that might work well in Florida as long as you could keep the nematodes out which seems like it could work.

ha, Garden Tower?
Sounds like a winner for space challenged, specially living in warmer areas where it will not go completely frozen during winter...
