How to Grow Sedum
No matter your expertise in gardening, you can grow sedums. Plant them in a sunny area with well drained soil and they almost take care of themselves. Sedums are happy in ground or in a container.

Propagating your Sedum
If you have sedum in your garden and want more, it is easy. You can propagate sedum in two ways.
- The first way is stem cutting. It’s simple, trim about a 3 to 6 inch piece off a stem from a healthy plant and remove the leaves on the lower half. Plant the cut end wherever you want a new sedum to grow. Sedums are so hardy they often root even if they’re just lying on top of the soil. Although, planting them gives them a better chance at healthy growth.
- The second way to propagate is by dividing and replanting. If your plants are too big carefully dig up the sedum and be gentle pulling apart the roots to separate them into sections. Then, replant the sections ensuring the top of the root is level with the soil line. This will increase the strength of a healthy new plant. Divided sections will also be quick to take root. You can divide tall sedum every three to four years. Propagating is simple enough even for the amateur gardener.

General Care for Sedum
Watering Your Sedum

Creeping sedums are resilient in super dry conditions. So if you are not sure if it is time water, err on the side of conservation and wait. Overwatering can hurt the plants more than not watering.
If you don’t like getting in the garden and pruning there is another reason to choose the sedum. Very little or no pruning is needed.
