Plants that prefer alkaline soil, like lavender and lilacs, can be harmed by the acidity of coffee grounds. Plants that are sensitive to caffeine, such as geraniums and some herbs, can also be affected by the presence of coffee grounds.Geraniums: Using coffee grounds on geranium seeds could inhibit plant growth. Azaleas: Although they tolerate acidic soil, the caffeine in coffee grounds could cause root rot and other fungal diseases.Salts: Coffee grounds can contain salts, which can build up in the soil over time and become toxic to plants.
