Lilacs: Container size/plant size?
A friend gave me a lilac sucker, which I planted in a 6" pot. The sucker was round 8" tall when I received it, and it's still about 8" tall. It seems healthy, though.
I'd like this lilac to live in a container next to my front door (urban gardener, I don't have the space for a bush in my narrow beds).
Could the small size of the container be limiting root growth, and could that be affecting the size of the plant above ground?
Should I just get a giant container now and stick the little sucker in it? What size container should the lilac ultimately need? How many years does it take for a lilac to reach a mature size?
