Q.Don’t know what kind of plant I have
I believe I have some kind of Palm. I’ve had it for a couple years. Not only do I not know what kind of plant I have, the tips are all turning brown.
My Palm has very stiff branches and almost appears to have some sort of thorns. Any information would be wonderful!
You have a Cycad plant, also known as Sago Palm, not true palm but an interesting and valuable plant.
The tip browning/die-back is likely from a water deficit, -- soil too dry. If it was recently planted/transplanted it could have been stressed with the move and soil/roots disturbance. Get a soil moisture meter and follow the watering and fertilization advise in the following article.
