I've been feeding them with Fruit Fuel soluble fertilizer monthly. I bought this fert through a member here. It's heavy on the Potassium.
I suspect the other large nana to the right is the Pisang Ceylon which shouldn't be far behind in budding. That leaves the short one to be the Apple variety I guess. These were all ordered and planted together.
