Spent grain for garden

Asked April 29, 2018, 5:51 PM EDT

Can I add spent grain (1-2 lbs dry basis) after brewing to my garden? We typically grow herbs, lettuce, tomatoes, peppers, & squash, sometimes melon. Just looking to repurpose it if it's beneficial to the garden soil. What about the rest of the yard which contains Kentucky bluegrass?

We recommend you either use it as a mulch or compost it. If mixed with soil the decomposition process uses too much nitrogen and your plants will suffer.
