‘If you’re in a region with frost, it’s generally not recommended to cut back coleus for winter,’ says Kiersten Rankel, a plant expert from the Greg app. ‘Instead, you can let your coleus die back naturally with the first frost, or bring them indoors to stay warm over winter.
‘If you’re in a frost-free area where coleus can grow as a perennial, or if you’re overwintering them indoors, pruning can be beneficial.’
Coleus in pots as part of container gardening ideas can be moved indoors, while plants in flower beds or borders need digging up and putting in a pot for winter. Another popular way of overwintering coleus is to take plant cuttings before the first frosts to grow indoors and plant outside after all danger of frost has passed in spring.

Cutting back coleus for winter has several benefits and can be done quickly and easily. It can help the plant preserve energy over the winter and set it in good stead for when it starts growing again next spring.
Kiersten Rankel claims that cutting back coleus for winter ‘helps maintain a compact shape’ and ‘encourages bushier growth’ for the next growing season. She recommends: ‘Trim back stems by about one-third to one-half of their height, making sure to leave several sets of leaves on each stem.’
If you cut back coleus before moving the plant indoors for winter, it ensures the new houseplant is a more reasonable size and not too large for any indoor space.
Coleus plants can grow anywhere from six inches to three feet tall and wide, depending on the variety. Therefore, keeping them to a more manageable size will be beneficial if overwintering them indoors as a tropical houseplant. A good trim will keep the coleus looking neat and compact.
The first step for cutting back coleus is to remove dead or diseased branches and yellowing leaves. Then assess the plant’s shape and decide on the size and form to which you intend to cut the coleus back.
Trim each stem individually by around one-third to one-half, using a pair of clean and sharp pruning shears, and cut to a set of leaves to encourage branching. It is also recommended to keep the prunings as they can be used to propagate coleus from cuttings.
After cutting back coleus that will overwinter outdoors, it is recommended to add some protection – especially if you live in a climate where temperatures may potentially reach levels that harm coleus.
Ward Dilmore, head landscape designer at Petrus, recommends: ‘Adding a layer of mulch on top of a cut back coleus would help protect it significantly from damage. This combined with a frost blanket would be ideal.’
Either use a thick frost cloth to protect plants from frost or get plant covers that can protect individual plants from any potential cold snap that may harm your coleus.
