If you read around, you can find various discussions about how to take care of palm trees.
“When I’ve tried forcing them off too much I’ve torn into the tree a little and I’m sure this is not a good idea, since buggies and pathogens could get in this way.”
“The one sago I picked up is sprouting its top to fertilize the females, seems though this process is taking all the nutrients and water from the fronds as they are all yellowing up.”
The palms of the imagination are less shaggy, less brown. I prefer real ones.
