Plants that do not like tea include those that are sensitive to acidity, such as camellias, azaleas, and blueberries. These plants prefer a more neutral to alkaline soil pH, and the tannic acid in tea can lower the soil's pH, making it more acidic. If you're looking to use leftover tea leaves or brewed tea as fertilizer, opt for plants that thrive in acidic conditions, like roses, ferns, and rhododendrons, instead.
