What is Ironite?
You may have heard of Milorganite, but what about Ironite? Ironite is a granular and liquid fertilizer product that can be used to improve the health and appearance of lawns, hollies, pin oaks, vegetables, ground covers, and more.

It is available in both a granular form, which contains 22% iron and 55% sulfur, as well as a liquid form with an acidic pH level designed to correct iron deficiencies in plants. Both products are approved for organic gardening by OMRI, making them safe for use on your garden or lawn.

This particular brand contains 22% iron plus 55% sulfur, so even if you have alkaline soils, this product will help balance out your desired range more effectively than most other liquid options available on the market today.

Mixing Ironite into existing topsoil can be an effective way of introducing much-needed micronutrients back into depleted ground over time, ensuring healthier, greener grasses and shrubs, etc.

So overall, utilizing this specific formulation alongside others during seasonally appropriate times throughout the year should ensure better results, faster, more reliable green-up periods from spring through fall months annually.
