A smaller variation of the raised bed is the so-called tomato bed, a garden implement that has unjustifiably slipped into anonymity; it creates the optimal growth conditions for plants that require a great deal of fertiliser and love a "warm foot" – as is the case with tomatoes. During the growth period, the biological waste accruing in the kitchen and garden can be directly disposed into the ring (which has been, of course, filled with good soil and fine compost); the ensuing decomposition process provides the vegetable plants with ground heat and excellent nutrients.
