Yellowing leaves, growing tree.

[just.wing.it]

I always used the balanced 20 20 20 blue powdered box. Using the ratio on the box. 1 tbs per gallon. it says 7-14 days, but during peak growing season I used every 7. due to my mixed results lately, i'll be switching back with quite a few of my trees..

How did it turn out?

So I used this stuff.
And it greened up the leaves on my bougie and my Amur in a couple weeks. Unfortunately, both the Amur and bougie died. I did not winter my bougie well enough and the Amur was blown off my bench while I was on vacation in the spring. But there is some great info, answers and debate on this thread.

I also switched the 20-20-20 for the rest of the summer. But I switched to all organic this year in my desire to encourage Moss growth. No major noticeable difference in growth. That chelates iron was used at any point I saw defficiencies.
