Issue 88 Plants That Don’t Do Well With Division

Division is a great way to get more plants without having to pay for them. However, not every plant tolerates this propagation method very well. You can divide them if you absolutely have to. But generally if a plant has a tap root or brittle roots, it’s easier to propagate it by another method, such as by seed, cuttings or layering. Here’s a list of some plants not to divide:
