I do seem to grow quite a number of plants in pots, and this means that I have a job to stop them getting pot bound. I mentioned this in my post about lilies.
Hostas make a great feature on one side of my terrace throughout the summer. The different shades of green against the warm terracotta pots look amazing on a sunny day. As long as I keep the worst of the slugs off, they look good for many weeks, only looking messy when they die back. The bonus is that they also produce attractive flowers in late summer.
After vigorous growth for two or three seasons, they may well need dividing. I am not very subtle about this. If the roots are very compact, the best way is to take a saw to them! I was hoping that my new Hori Hori digging tool might help but it needed to be twice the size to get the job done.
I can see that I will run out of hosta space before long but I know my neighbours can take a few pots off my hands.
