Q.Winter Browning of Sago
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.

You will need to remove the yellow and brown fronds this spring but only those as they will not come back. Just use sharp shears to do so. Do not remove green fronds. These articles will help you as well:

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.
