Fronds All Yellow/Brown

Question

We had two to three days of 15 degree nights. All of my palms and sago fronds are completely brown. How do I prune them to allow new growth to start in the spring and summer?

Answer 1

You will need to remove the yellow and brown fronds this spring but only those as they will not come back. Use sharp shears to do so and do not remove any 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 the fronds grow back.
