All plants, including water-thrifty cactus and succulents, need a consistent supply of nutrients to thrive. Fortunately, this liquid fertilizer concentrate makes feeding them so easy! 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. This special formula is enhanced with kelp extracts, humic acids, and a proprietary set of beneficial microbes to ensure optimal results. We suggest feeding plants every two to four weeks.
