I have a Dracaena Fragrans that I got from my wife's classroom. It thrived there, was a lush green and about 5 ft tall. I moved it to a corner office with lots of windows facing south and east. I assume it is getting much more light than before, some direct in the mornings and evenings.

Since then it has gradually gained yellow spots and patches that turn brown. The ends of leaves are turning brown, with some eventually dying back to the stem.

I am looking for ideas of what can be wrong, and if I can do anything to help. Can I prune back and let it start over in it's new light environment? It is pretty ugly by now...

Thanks!
Matt
