Feed Them Coffee and Egg Shells
Try mixing coffee grounds or egg shells into the soil. Yup. Garbage. Store-bought potting soil has all the nutrients your plants need, but about once a year, calcium-rich egg shells can give plants a great boost (do it too often and you’ll change the soil’s pH balance). Clean off the icky stuff, let them sit out to dry, and then crush them to a coarse powder. Pour that around the base of the plants, and water.
Coffee grounds have nitrogen — yummy for plants. Different plants like a different amount of coffee, just like humans. To get a sense of how much to use, start with a teaspoon a week mixed into the soil, and then increase the amount until your plants stop showing signs of improvement. Then it should be good to go for a while.
