My sago fronds are brown from the cold. What do I do? They are in the ground. And very big. Do I cut them all off? Is it true to fertilize them with epsom salt?

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 parts of fronds.
