Repot water-stressed, container-grown plants. We're heading into what's usually the hottest part of the summer, so now is the time to repot any pot-bound plants that are drying out too quickly. You can tell if this is going on when leaves wilt frequently, roots creep out the drain holes, or the plant actually pushes up out of the container. You can reuse the same container as long as you first loosen the roots and trim one to two inches all around the root mass. Put an inch or two of fresh soil in the bottom of the container, set the plant on top of this layer, and use more soil to fill in around the sides of the root mass. If you'd rather not root-prune, then replant in a container at least three to four inches wider in diameter than the original.
