I planted a fig tree a few years ago. Now it's just two 10' stems with a few leaves on top. One neighbour has a more mature tree which looks just like mine except with more stems. While another neighbour has a short tree with a tick stem? Are we growing different sort of fig trees or is there a way to encourage (trim) my tree to look more like a short/thick tree? Alternatively, what is the ideal sort of fig tree to grow in Vancouver that will be short and produce lots of fruit?
