Meyers Lemon Sucker?
I have a potted Meyers Lemon that had a recent growth spurt. I'm concerned it may be a sucker because of how quickly it grew and it's down on the base. However I have another brand just a nose hair above it that has fruit on it. Please see photos. You'll notice the new growth is quite large- it grew over a foot in the last 6-8 weeks.
