Yellow Leaf Problem Solved
Is your shrub or tree producing yellow leaves, and not green leaves? The yellow leaves are a sign of iron, magnesium, or zinc deficiency, also called Interveinal Chlorosis. When your plant has chlorosis it simply means that they are in need of more nutrients, in order to grow those beautiful green leaves. A soil test is always a good idea when it comes to determining the root of the problem. I found a great article from the Morton Aboretum's website that explains in depth about chlorosis and what short term and long term actions you can take to lessen the effect chlorosis will have on your plants.

I had a customer, who contacted us about her Limelight Hydrangea showing visible signs of yellow leaves and what could be done about this issue. Our customer knew it was due to either a magnesium, iron deficiency or overall a lack of nutrients, but wasn't quite sure which plant care product to invest in. In today's times there is a world of information out there, but this post was created to give you a simple list of trusted products to eliminate those unattractive yellow leaves.
According to the article by Chris Bond from Maximum Yield, "Location will matter," when determining which what kind of chlorosis you might be dealing with. The article, clearly states if you see yellow leaves stemming from the top of the shrub, then your plant is most likely experiencing an iron deficiency. If the yellow leaves start from the bottom, but not the top then it is experiencing a magnesium deficiency.
