Update:
So it has been one year to the day since building these beds. Here is an update. I am sorry for the poor audio. Basically, I have not watered this bed for an entire year and it is growing great. The only water it has received came from mother nature and the little water I added when planting new starts or seeds. This bed has been an amazing success and I have plans to expand and make it even better. Growing in the bed are tomatoes, chard, purple mustard, purple and orange sweet potatoes, morning glories, and a little baby Moringa. Stay tuned for Future updates.
