How can I tell if my Meyer Lemon is a dwarf or not? It didn't say that on the label but it's very small and I've had it for a year.
All Meyers are small trees, even when mature.
It's difficult to talk about the growth rate of your plant since we know nothing about the cultural conditions it is being grown under. Growth rate depends upon such factors as light quality and duration, type of soil, container or in-situ, watering and fertilizing practices, temperature of the environment, as well as the general genetics of the plant.
Well you cant really, not that Im aware of. How old is it? Is it in ground or in a container? Meyer lemon doesnt get too big even on standard rootstock.
