Milorganite Fertilizer

Yes, Milorganite is safe for use on vegetable gardens. Because it is a slow-release, organic-based fertilizer, it provides steady nutrition without the risk of burning your plants.

No, Milorganite has an NPK ratio of 6-4-0, meaning it contains nitrogen and phosphorus but no potassium. You may need to supplement with a potassium-rich fertilizer if your soil test indicates a deficiency.

You can apply Milorganite throughout the spring, summer, and fall growing seasons. Because it is a slow-release formula, it feeds your lawn consistently over time rather than providing a quick, short-lived burst of growth.

One of the primary benefits of Milorganite's slow-release formula is that it will not burn your lawn, even if you apply more than the recommended amount. It is a very forgiving product for those new to lawn care.

Milorganite has a neutral pH range of 6.5 to 7.0, so it will not significantly alter your soil's acidity or alkalinity. The added iron is included primarily to help promote a deep, green color in your lawn and plants.

Yes, Milorganite is shelf-stable and can be stored indefinitely as long as it is kept in a cool, dry place. Ensure the bag is sealed tightly to prevent moisture from clumping the granules.
