Q.Sago palms
I have a group of three Sagos and one is turning yellow. I had scale on two of them and washed them clean and sprayed them with insecticide. A year and a half ago I did remove three baby plants crowding the one that’s turning yellow (not sure if that I created this problem or if it’s something else). I live in southern Texas.

The yellowing sago palm may be suffering from a nutrient deficiency, which could have been caused by competition from the baby plants. Please see these articles for advice:
