Chelated Iron

I picked up some Bonide #299 Liquid Iron Complex quite cheaply (about a third the usual price), so I've applied that to the lawn.

The recommended rate for bluegrasses is 2 to 6 ounces per thousand square feet in enough water to apply it, and then spray to runoff. I diluted 2 ounces in 1 gallon of water and found it made a slightly thin spray. Next time I'll dilute half that in a gallon and go 500 square feet.

The hydrangea, which was a touch yellow, is showing a response in just a few hours. The grass should take 1 to 4 days to show any change at all. Since I went at 1/3 the normal rate, I may also have to apply more to achieve the color I want.
