Keep up with growth spurts
Feed growing plants with a slow-release houseplant fertilizer according to label directions. When the plant begins to outgrow
its pot (about every year or two), move it into a slightly larger container (about 2 inches wider). If you’d rather keep it
in the same pot, prune the roots using this technique: Knock the plant out of its pot. Then, using a sharp knife, shave roughly
an inch off the outsides of the rootball; don’t remove more than 20 percent of it. Refill the gap between the shaved rootball
and the pot sides with fresh potting soil.
