Know before you buy
Yes. Because it is OMRI listed for organic gardening, it is perfectly safe and effective for use on vegetables, herbs, and leafy greens.
The granular form is designed to prevent ingredient separation, ensuring that every scoop contains a consistent mix of nutrients. You can easily spread it by hand or with a spreader for even coverage across your garden beds.
The 5-2-4 ratio provides a balanced supply of nutrients, with a slightly higher nitrogen content to encourage lush, green foliage. This makes it particularly well-suited for leafy vegetables and herbs that require steady growth.
This is a continuous-feed fertilizer. It is formulated to break down gradually, providing your plants with a steady, reliable supply of nutrients rather than a sudden, short-lived spike.
While it is formulated to support vegetables and herbs, the nutrient profile is also suitable for lawn maintenance. However, given the 4-pound package size, it is most practical for smaller garden plots or container gardening.
