Ironite is needed when the soil is lacking in iron. You can know this by running a soil test. The best time to apply ironite is during spring when your grass is readying for exponential growth. This is the period it needs the iron for exponential green growth.

Can you apply Ironite and fertilizer at the same time?

The answer is yes. You can apply both ironite and fertilizers to your lawn at the same time. However, since ironite is a supplement, you should first be aware of whether your plants or the grass, in general, are deficient in certain nutrients or not.

Can you put down too much Ironite?

You can add around 1 pound per 100 square feet if you feel necessary. Remember, using too much Ironite will not make your lawn greener; the grasses instead will turn blackish-green and eventually die.
