I bought some chelated iron to spray on my maple that has chlorosis. It’s a 4.5% solution of EDDHA iron (that’s the kind of iron molecule it is derived from, which matters for our alkaline soils if I use it as a soil treatment). I sprayed it on the tree today, and we’ll see if it greens up within the next week or two. I did the spraying in the evening so it would be less likely to suffer leaf burn.

I also sprayed the iron on my rose hedge, hoping it will improve the flowering, because I’m mystified about why those roses aren’t blooming well.
