Grow The Love

We’re a small team of botanists & plant chemists dedicated to creating healthy, sustainable nutrients for your garden.

Bloom City’s formulations are better for plants, people, and the planet. Our small team of botanists & plant chemists offer conscientious growers a clean and simple alternative to Big Ag fertilizers.


Raise Plants Healthy & Strong

We created a line of Plant Nutrients supplements that provide essential nutrients and organic compounds plants need to grow strong.

Keep It Simple & Safe

Big fertilizer firms use harmful, outdated chemicals that are bad for people and the planet. Bloom City’s nutrient systems offer craft growers a safe solution for large, clean blooms.

We Love Big Yields

Bloom City’s unique formulas and probiotics generate high-quality yields without the low-quality, filler ingredients of other brands.

Better For Our Plants & Our Planet

Our sustainable fertilizers use many organic ingredients like wild Atlantic kelp, fish bone meal from the Pacific Northwest, and solar-evaporated potassium rather than industrially mined, all sourced in the USA.

The Plant Nutrients Series


Holistic Health For All Plants

From houseplants to hydroponics, our nutrient systems have what you need for beautiful, healthy growing.
