It's easy to overlook the fact that houseplants need a consistent supply of nutrients to thrive. Fortunately, this liquid fertilizer concentrate makes feeding them so easy! The bottle even pre-measures the dose for you. Simply close the lid, turn the bottle upside down, and then right-side up. Flip the lid open, pour the contents of the Easy Dose cap into your watering can, and add 1 quart of lukewarm water. The blend is enhanced with kelp extracts, humic acids, and a proprietary set of beneficial microbes to ensure optimal results. We suggest feeding houseplants every two to four weeks.
