root pruning potted boxwood??

I have six boxwoods in 18" Mexican pots and I'm thinking that they are probably pot bound. They've been in these pots for at least 5 or 6 years and they are not holding moisture for very long. I've heard of "root pruning" but I've never done it. Any thoughts? I would prefer not to get bigger pots for the deck they are on.

I've also had the Mexican pots break apart when I try to get a pot bound plant out of them. I would like to try to save them - any way to prevent that? - although they're so inexpensive at the NorCal outlet, it's not a huge big deal...

Once you get them out of the pots, trim off about an inch of old soil and roots all around, and then repot with fresh soil and add some time release fertilizer. Try using a sharp kitchen knife against the sides of the pots to more easily get them out.

Five or six years in the same potting soil, the organic components are surely long ago turned to dust. Every three years I would change the soil and re-prune to keep your boxwood looking its best. Al
