How can I tell if my jade plant is root bound and in need of repotting?

You can tell if your jade plant is root bound and needs repotting by checking if the roots are tightly packed and circling around the bottom of the pot. If the plant is struggling to absorb water or nutrients, or if the roots are growing out of the drainage holes, it's a sign that it needs a larger pot. Repotting will give the roots more space to grow and help the plant thrive.
