will this burn the grass

Use just ironite an it won’t burn your grass...it is safe for all shrubs an trees an plants

Only put this down right before a light rain so the grass can drink it up when it mixes with the rain. It may burn the grass if you put too much down and it sticks to the grass when dew forms and with little rain.

Hello, Since it has been two months since you fertilized we wouldn't expect the Ironite Plus 12-10-10 to cause a burn. Generally speaking you want to time fertilizer treatments about 6-8 weeks apart. You wouldn't want to fertilize any more than four times in a growing season. Thank you
