Q.Sago Palm Frost Damage
My sago palm was hit hard during a freeze. The fronds are all yellow on the tips and very little green is showing. Will it come back? Do I need to do anything other than fertilize and water?

You will need to remove the yellow fronds, but only those, as they will not come back. Just use sharp shears to do so. Do not remove green parts, should any begin to appear.

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.
