    In 2016, a publication called Plant Signaling and Behavior looking at the efficacy of concentrated levels of caffeine on fungal activity in soil. We know that fungal disease is often transferred to tomatoes by soil-contaminated water splashing back on the underside of leaves. If we could lessen the fungal activity, that would be great!

    The problem is the same, however, with the slug issue mentioned before. Concentrated levels of caffeine are just not possible in coffee grounds. Amending soil or adding them to compost will likely all help the general health of your soil, but that wont achieve the same results as the study.

    Other studies like this one, have looked at how different soil amendments increase the microbial activity in your soil, thereby suppressing fungal diseases. The study, unfortunately, only looked at one type of disease Fusarium Wilt and only in spinach. So while the results were encouraging, the potential impact is unknown for other plant species or other fungal diseases.
