Recently we had a bad freeze in Austin, Texas, and I have two sago palms outside that were not protected. It got down to 19 degrees and now the leaves are brown. I do not know if the palms are damaged or not. It took about five years for the leaves to form. My question to you is: If the palms are still alive, what can I do get them back in good health?

We have a very large Sago palm with many heads and pups. It is in a very small area and needs to be removed. How deep do the roots go? Must we dig it up, or can we cut it back and kill it?
Cut it back and paint the open wounds with undiluted Round-Up right after you cut the main plant down. This should kill it without having to dig up the roots.
My Sago Palm tree has white scale on it. What kind of spray should I spray on it to fix it up? I would like to know how to treat the tree from the white scale.
I would recommend neem oil. It is organic and harmless to humans and pets but still kills scale very well. Here is more information: https://www.gardeningknowhow.com/plant-problems/pests/pesticides/neem-oil-uses.htm
I have a sago palm about 15 years old. It is too tall. Can it survive if it is cut down?
Sago palms do not respond well to pruning and can be killed by pruning.
There is no easy way to reduce the size of this plant, but if you cut back on water and fertilizer, this will help to keep it from growing larger.
I have a sago palm by my front door, and it is getting awfully big. Is it possible to 'top' the palm?
It is generally nor recommended that you prune sago palms for height as this will most likely kill the plant. Sago palms do not respond well to pruning. I am afraid there is not much that can be done to reduce their size. Here is an article that you may find helpful: https://www.gardeningknowhow.com/ornamental/trees/sago-palm/prune-sago-palm.htm
We have a large Sago Palm that we have had for about 8 years. We live in Louisiana. This winter we had a hard freeze (16 degrees) and five inches of snowfall. Now, all of the fronds are brown. What do you recommend?
I would wait until spring to cut back the plant. But, you will need to remove only the brown fronds (or yellow) as they will not come back. Do not remove green fronds. These articles will help you as well:
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?
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.
