Adding boron for blooms
Last year, from this site, I received information to try boron for a lilac that had never bloomed since I had put it in 8 yrs ago. Well I had a bloom this spring. Not fantastic but it did bloom. I want to add boron again but I do not remember what I did or where I got the boron. Can someone steer me in the right direction? I did add it to the soil but that is all I can remember.
