Organic-based, Joyful Dirt’s Houseplant shaker works well for indoor houseplants and is safe to use around curious pets and kiddos. Give a light shake (~1/8 teaspoon) on top of your plants’ potting mix before watering or add directly to your watering can and stir. This product won’t cause fertilizer burn if overused, but we recommend using it about once a month for more vibrant, larger houseplants.
