Country Living reports that gardeners can preserve coleus through winter by taking stem cuttings before frost and rooting them in water. Roots typically form in about two to three weeks; the cuttings can then be planted in soil and kept indoors until spring.
Gardeners can keep coleus growing through winter by taking stem cuttings before the first frost, according to a Country Living gardening report. The cuttings can be rooted in water, moved into soil and grown indoors, offering a way to preserve plants for spring planting rather than starting over after cold weather.
The report recommends taking a 4- to 6-inch cutting while the weather is still warm. Use sharp, clean scissors disinfected with rubbing alcohol, then remove the leaves from the lower portion of the stem. Place the cutting in water so that the part where those leaves were removed is submerged. Rooting hormone may be used, but the report says it is not necessary.
Roots generally develop in about two to three weeks, according to the report. Once rooted, the cutting can be transplanted into soil and grown as a houseplant over winter. The report says the plants can move back outdoors in spring when soil temperatures are above 60°F; it does not provide a specific calendar date, since suitable timing depends on local conditions.
The method is intended to preserve coleus, which the report describes as an annual that dies back when frost hits. Taking cuttings before that happens gives gardeners a way to carry the plant into the next growing season. The advice is presented as a propagation method, not a guarantee that every cutting will root or thrive indoors.
Keeping Coleus for Spring Planting
For gardeners who want to keep a particular coleus variety, taking cuttings can preserve a living plant through winter instead of relying on buying another plant or growing one from seed in spring. That may be useful where coleus is grown for its colorful foliage in shady garden beds or containers.
The approach also lets gardeners start with a rooted plant when outdoor conditions become suitable. The practical deadline is the first frost: once cold weather damages the outdoor plant, the opportunity to take healthy cuttings may have passed. Because the report gives no local frost dates, gardeners need to use their own forecast and growing conditions to decide when to act.

A Seasonal Propagation Method
Coleus is commonly grown as an annual in gardens and containers, according to the Country Living report. Its foliage comes in varied colors and patterns, and the plant is often used in shady areas. The report notes that coleus is related to mint, a detail relevant to the propagation advice because it describes the plant as quick-growing and straightforward to root.
The recommended process has two stages: root a cutting in water before frost, then grow it in soil indoors over winter. In spring, wait until the soil is above 60°F before moving it outdoors. This temperature threshold comes from the supplied report; it is not a forecast for any particular region, and gardeners should account for local weather and the risk of further cold.

Rooting Results Vary by Conditions
The report does not say how many cuttings typically survive, or how indoor light, temperature and watering affect success. Its two-to-three-week estimate is a general timeframe, and individual results may vary. It also does not give region-specific frost dates, so gardeners must determine how much time remains before cold weather locally.
The guidance does not specify a particular indoor location or care schedule for rooted plants. Nor does it establish that every coleus variety will respond identically. The supplied material gives a general method and temperature threshold, but no independent trial data or expert quotations beyond the report itself.
Root Cuttings Before Frost Arrives
Gardeners considering the method should take cuttings while the outdoor plant is still healthy and before frost is forecast. After preparing the stem and placing it in water, check for root development over the following weeks. Once roots have formed, plant the cutting in soil and keep it indoors through winter.
For spring, the report advises waiting until soil temperatures are above 60°F before returning coleus outdoors. Local forecasts and garden conditions will determine when that point arrives. The report does not identify a further update or a single national date for moving plants outside.
Key Questions
When should I take coleus cuttings?
Take them while the weather is still warm and before the first frost damages the outdoor plant, according to the Country Living report.
How long do coleus cuttings take to root?
The report estimates about two to three weeks. That is a general timeframe, not a guarantee for every cutting.
Do I need rooting hormone?
No. The report says rooting hormone is optional and that cuttings can be placed directly in water after their lower leaves are removed.
When can I move the plant outdoors again?
The report recommends waiting until spring, when soil temperatures are above 60°F. Local weather and the risk of frost still matter.
