I have been using Howard Palm Fertilizer. The bag says boron in kind of big letters on the front. What's the boron for? (My queen palms still look happy.)
Our palms do not have any yellow on them now. But before I started fertilizing regularly, the queens had a couple of yellow fronds, always at the bottom. I had them cut off because I knew they would not turn green again.
Would you please explain what yellow fronds indicate and what to do about them? Did I do the right thing by cutting them off and now fertilizing on a regular schedule? The trees look fine so I guess I did OK. But I would like to know more about yellow fronds.
Thank you.
