Gardeners can keep coleus through winter by taking cuttings before frost and rooting them in water. Country Living’s guide says roots typically form in about two to three weeks; the rooted cuttings can then be planted in soil and grown indoors until spring.
Gardeners can preserve coleus plants before the first frost by taking short stem cuttings and rooting them indoors, according to a Country Living gardening report. The method offers a way to keep plants for spring rather than relying on outdoor coleus to survive winter temperatures.
The report recommends taking a 4- to 6-inch cutting while the weather is still warm. Use sharp scissors cleaned with rubbing alcohol, remove the leaves from the lower part of the stem, and place the cutting in water up to the point where those leaves were removed. Rooting hormone can be used, but the report says it is not necessary.
Roots are expected to form in about two to three weeks, according to the article. Once rooted, the cutting can be transferred to soil and kept indoors as a houseplant through winter. The idea is to move the resulting plant outside again in spring, after soil temperatures rise above 60°F.
The article advises taking cuttings before frost arrives. It does not give a specific regional date, so gardeners need to use their local forecast and conditions rather than treating a calendar date as universal. The guidance describes a propagation method; it does not establish that every cutting will root or thrive indoors.
Keep Coleus for Spring Planting
Because coleus is treated as an annual in the report and is vulnerable to frost, an outdoor plant may die back when freezing weather arrives. Rooting cuttings provides gardeners with a way to carry a favored plant through winter and avoid starting again from seed or buying a replacement in spring.
The approach also lets gardeners preserve particular foliage colors and patterns they already have. Its practical value depends on taking cuttings in time and maintaining suitable indoor conditions; the source does not promise that every plant or cutting will succeed.

Why Frost Changes the Plan
Coleus is commonly grown in shady garden beds and containers, where its patterned leaves add color. Country Living describes it as a fast-growing member of the mint family and notes that it can be used as ground cover or in mixed containers.
The report’s seasonal advice is to propagate before frost rather than wait for the outdoor plant to be damaged. It proposes a simple sequence: take a cutting, root it in water, pot it up, and keep it inside until spring. It recommends waiting to return the plant outdoors until soil temperatures are above 60°F.
““The trick is simply to take a few cuttings of your coleus while it’s still warm out and root them.””

Rooting Time Can Vary
The source gives about two to three weeks as the expected rooting period, but does not specify conditions such as indoor light, water temperature, or how often the water should be changed. It also does not provide a success rate or explain how to troubleshoot cuttings that fail to root.
Frost timing and spring soil temperatures vary by location. The report offers no local forecast or planting calendar, so the appropriate date to take cuttings—and when to move them back outside—remains dependent on local weather and garden conditions.
Take Cuttings Before Frost
Gardeners following this advice should take cuttings while the plant is still healthy and before a frost reaches their area. After roots develop, the cuttings can be moved into soil and grown indoors through winter. In spring, check that soil temperatures are above 60°F before returning the plants outdoors, as the report advises.
The source does not provide a specific frost date or a detailed indoor-care schedule. Gardeners will need to monitor local conditions and the cuttings as they grow.
