I live in the Houston area and had an unusually harsh winter. My sagos are, what I consider, burned from below freezing temps. They are now brown, but with green stems and a few patches of green. What should I do? They are outside and we have had a very wet winter and spring so far.

It is hard to say how well they will grow back. Sago palms do not deal well with lost fronds, but they have been known to recover fine.
