Espoma Organic Orchid Bloom Booster Plant Food, 8 oz ideal for use with all orchids & bromeliads. Have a reputation for being a bit fussy, but given the proper conditions — including fertilizer — they'll reward you with stunning, long-lasting blooms. 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. 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.
