I bought a croton last year from a garden centre, because the price of it was reduced and I am a sucker for trying to revive neglected plants (which I do extremely well), and it was doing fine; I repotted it the same year as the roots were already crowding the pot, and now, a year later, the roots are, once again, severely overcrowding the pot. I've never seen such a potbound plant.

The problem is, the stem of the plant is only the width of a 2b pencil and it is in a pot 5 inches wide, and the roots are overcrowding the pot so much that the soil seems to be drying out every 2-3 days.

What should I do? Should I repot it or attempt to prune some of the roots back?

Thank you!

PS. It is very healthy, it's putting out a new leaf once every couple of weeks. It's showing absolutely no signs of dying. Do they like being potbound, or something (I know some plants do)?
