Yeah afternoon sub and summer heat are no good. I tried some and had to move them. The sun just burned them up.
Since they have not been fertilized I picked up some osmocote to apply now. I also ordered some jacks water soluble and will try to foliar feed every few weeks. I may end up needing some iron if they don't grow out of the yellowing.
