How To Keep Coleus Healthy In Pots In Summer

Coleus is a versatile container plant because it takes sun or shade. Its boldly colored and textured leaves are an eye-catching addition to your containers. Just be careful because It can become become lanky and gangly as summer progresses, but the simple solution is pinching it back.

The simple solution to avoid leggy or lanky plants: continually pinch or cut it back. The pinching back will spur the plant to make new branches and you'll get a bushier, fuller shape. Two new branches will begin to grow from where you pinched.


You can also pinch back just under the flower buds if you don’t want the plant’s energy to be spent on producing flowers and seeds. Once the plant starts flowering the leaves lose beauty and vigor.

Around midsummer, prune your coleus plant hard regardless of whether it'll be allowed to flower. If the plant isn't maintained, it could become overgrown and its branches can snap from their weight.
