Winter Weather (Sago Palm)

Question

When it turns brown or looks dead after the winter months, what should you do? Should you prune or not?

Answer 1

You will need to remove any yellow or brown fronds this spring, but only those, as they will not come back. Use sharp shears to do so. Do not remove green parts of 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. I would wait a whole season to see if fronds grow back.
