Q.crinum lily
I bought a crinum lily bulb last year at the Master Garderen Show planted it in the ground as I was told to do. Went back north from Silver Springs Fl. The big black grasshoppers chewed on the leaves while we were up north. When we returned to Fl. I dug it up and put it in a 10 in. pot. It has new growth coming at the top but now there are reddish stripes on the lower leaves. What kind of fungus is this and is there anything that I can treat it with? Should I take it out of the pot and plant it in the ground or Should I take the pot back north for the summer to treat the plant?
This is usually stress induced, or a phosphorus deficiency.
