Can I add coffee grounds to monstera?
No. Coffee grounds have no use to your plants. Dead plant material needs to be broken down completely before any nutrients in it are useful for your plants. That means they need to mold and be eaten by invertebrates and pooped out. You don’t want that happening in your plant pots. While applying coffee grounds directly onto the soil around most plants is usually fine, this should be done with care and moderation, as using grounds in this way is never a one-method-fits-all approach.Don’t just pour it down the drain — you can use it to fertilize your plants, both indoor and outdoor. Coffee grounds (and brewed coffee) are a source of nitrogen for plants, producing healthy green growth and strong stems. Coffee also contains calcium and magnesium — both of which are beneficial to plant health.
