We ran out of steam there. The section in front only needs one more layer of compost and then a layer of pea straw.
The beds consist of layers of shredded paper, pea straw, compost, kitchen scraps, horse manure and chook manure. (Not in this order.) This combination works extremely well. We just let them sit a while before planting in them. These beds will be ready by the end of October / beginning of November.
I guess these two beds might be able to accommodate about 26-28 tomato plants. (They are very long and wide beds.)
