How to Add Yeast to Poor Soil

Adding bread yeast to your garden is an organic, inexpensive way to enrich your soil or potting medium and promote healthy plant growth. Yeast contains B vitamins and protein that nourish plants and accelerate the growth of beneficial bacteria. You can add a yeast-based compost tea directly to soil or pour it in your compost to help break down organic matter.
