Flourish Organic Plant Food

We've partnered with Flourish to bring you a sustainable plant food to help your Costa Farms plants thrive.



We are on a mission to help everyone find their green thumbs. Our own roots go way back— competing against each other in science fairs in high school. We’ve always bonded over our love of the natural world and that translated into a love of houseplants and a desire to bring amazing plant care products to the next generation of plant parents. We’re thrilled you’ve chosen Flourish Plant Food; let’s grow together!

Flourish Plant Food is a naturally-derived, organic blend of essential nutrients and microbes that help sustain healthy plant growth during vegetative (leafy) growth, and the early stages of flowering or fruit production. 70% quick-release, plant-ready nutrients plus 30% slow-release, microbe-dependent food make it last just long enough, and it’s 100% water soluble.


Flourish’s gentle formulation of macro- and micronutrients protects from the overeager plant parent’s tendency to over-fertilize or “burn” plants with synthetic chemical based fertilizers. We feed your plants and soil with a carefully balanced dose of naturally derived nutrients and plant-friendly microbes to enhance growth and resilience.

Sustainability is at the core of what we do, so our plant food is derived from sustainable sources (including fish and corn discards from the food system). Don’t worry, no fishy smells—just a subtle minty fresh aroma from organic essential oils.
