is yeast good for compost
A. Absolutelyâespecially if that bin is mostly filled with shredded leaves; yeast is alive with the kinds of organisms that naturally move the composting process along. Mix the yeast into all parts of the pile and make sure that the 'dry browns' in the pile are good and moist.
Adding brewer's yeast to the compost pile speeds up decomposition and increases heat. For gardeners who practice vermiculture or raise worms in the compost pile for their castings, the addition of brewer's yeast increases the growth of worms and the quantity and quality of worm castings produced.
