Our Core Values

As one of the 17 essential plant elements, iron is commonly applied in various lawn, turf and landscape settings. Often, Ferrous Sulfate fertilizer is used to correct Chlorosis (yellowing of the leaves). In the plant, iron plays a role in photosynthetic electron transport, respiration, chlorophyll formation, and numerous enzymatic reactions. Due to its use in chlorophyll formation and photosynthesis, Iron (Fe) is often applied to enhance greening without increasing plant growth.

*Large Trees:

Liquid Application: Pour the Ferrous Sulfate fertilizer solution onto the soil.

Note: We recommend applying fertilizer early in the morning or late in the afternoon to avoid burning plants.Do not apply when temperatures outside exceed 65 degrees Fahrenheit.

We register all of our products through the California Department of Food and Agriculture (CDFA), ensuring the top quality possible.

CDFA is the highest regulated government agency and we not only meet their requirements, but exceed them. The heavy metal content of our products are either at zero or fall below amounts allowed by CDFA.

We take pride in knowing we are a certified and minority owned small business.

Innovation is not exclusive to just one particular individual, but comes from those of all walks of life and we demonstrate this on a daily basis.

Our small business background is key to the trust we've built with our customers over the years and allows us to remain transparent while embracing community values.

We understand that we only have one Earth and it's up to us to take care of it!

We're doing our part by offering heavy metal free fertilizers that feed your plants the nutrients they need without harming the environment.

We even carry fertilizers suitable for Hydroponics to encourage fellow gardeners to practice cultivation methods that reduce water usage.

Meanwhile, our high quality, natural supplements encourage a shift away from synthetic medicine and towards a more holistic approach for personal wellness.

There's no better feeling than giving back to one's community and we decided the best way to do this was by creating our very own non-profit organization, Greenway Foundation.
