QuestionI live in southern Ca. next to the ocean. I have several Sago Palms in my yard that are 15 years old. Recently the fawns on two of the larger ones have turned almost totally yellow. The smaller attached pups have done the same. The two plants are within ten feet of eachother. They receive moderate water and are in the sun most of the day. The fawns were very green and soft and then turned very quickly to yellow. One of the plants has thrown new fawns and they are now starting to turn yellow. I have used palm food and someone said add manganese because they might be deficient. It only impacts these two sago's even though there are two more near by. None of the sago"S in the back yard are impacted. There are no signs of bugs on the plants.I have shown the fawns to several nursery people and no one has identified the problem. Any help you can provide would be greatly appreciated. Thank you...Don
AnswerDon:
I'd be inclined to focus my attention to the soil conditions. I suggest a soil test. You can contact your local county Agriculture office or the nursery business that you mentioned about having this done. It is a good idea and may identify nutrients that may not be available to your plnat. It will also give you the pH which is important for nutrient uptake. Be sure that the soil drains well also. If water is allowed to accumulate over an extended period in the root area, this may lead to a root rot.
