Not necessarily. Any idea how cold you got this winter?

Look up the Cycad Jungle. A fellow named Tom Broome is the expert in central Florida.

The Sago is not really a palm for a cyad! This plant is deadly to humans and pets. We tore ours out of the garden when we lost our dog to this deadly worthless plant!

Sorry to hear about your dog Enelram. A lot of common plants are toxic to animals (Oleanders, Peace Lilies, Cycads, Philodendrons, ivy, Japanese yew, Schefflera, Birds of Paradise, and lots of other common plants in the Florida home and landscape). Always make sure that kids and pets have no contact with poisonous plants and if thats not possible, then plant only things that are not deadly if eaten (most palms are not a problem, most cycads are).
Some plants that look harmless are deadly if eaten (oleanders are actually one of the most toxic plants in the world even though they dont look it!).

It looks like your sago palm is cold damaged but if its alive it will make a new flush of fronds when the weather is consistently warm.

Good luck!
