Question
In April of this year I bought a 2yr old citrus cocktail tree which grows myer lemons,  limes, navel oranges, grapefruits, and honey bells. I planted it as instructed and have been using the recommended Rite Green 4-6-8 citrus fertilizer once a month. The tree is doing great it has grown a foot or more since April and I already have 2 pretty good size lemons starting to grow. However, I recently noticed that the leaves of the honey bell stock are starting to turn yellow, as I am a new citrus owner I was wondering if this is normal or not. And if not what do I do about it? I spent a lot of money on this tree and I love citrus so I was hoping to get many years and lots of fruit out of the tree. I live in Jacksonville, Fl the tree is in full sun and gets the afternoon down-poors of rain daily. I wasn't sure if maybe this was a sign of to much water, but then why is it only part of the tree specific to the honey bells and how do you stop the rain if that's the problem???
Thanks for your help,
Lindsay

Answer
Hi Lindsay,  Citrus may occasionally suffer from a deficiency of zinc or iron. When these nutrients are
deficient, the tissue between leaf veins turns yellow, but the veins remain green, at least
initially. Foliar sprays containing chelated zinc or iron can be used to correct these
deficiencies.  Iron deficiency can also be caused by excessively wet soil or by very alkaline
soil (pH above 7).  kathy
