A Homes & Gardens gardening report highlights eight plants that may need winter protection, including some commonly treated as hardy. It recommends preparing for local frost, winter wet and wind, with care tailored to each plant and its growing conditions.
Homes & Gardens has published a winter-protection guide urging gardeners to check forecasts and prepare vulnerable plants before hard frost, rather than relying only on plant labels. The report names eight plants that can be more exposed than their reputation suggests, including lavender, coral bells, bigleaf hydrangeas and rosemary.
The report says newly planted shrubs, container plants and species vulnerable to wet or wind may need attention ahead of the first hard frost. Suggested measures include mulching roots after the soil cools, insulating pots and using breathable covers when cold weather threatens. It cautions against trapping moisture around foliage, which can contribute to damage or rot.
Several plants need protection for reasons other than simple cold sensitivity. Lavender can be harmed by cold, waterlogged soil, especially in heavy or poorly drained beds. Coral bells have shallow roots and crowns that repeated freezing and thawing can lift out of the ground. Bigleaf hydrangeas may survive winter but lose flower buds formed on old wood, while rosemary is vulnerable to cold, wet roots.
The remaining plants named in the report are Japanese maple, gardenia, evergreen shrubs and potted plants as a broader category. It says young or container-grown Japanese maples face more exposure than established trees, and recommends sheltering or insulating pots. The supplied report text ends during its gardenia section, so it does not provide the full advice or details for every one of the eight entries.
Protecting Roots, Crowns and Buds
The practical point is that winter injury is not determined by a hardiness label alone. Drainage, wind exposure, plant age and whether a plant is in a pot can change the risk. A plant may tolerate freezing temperatures in suitable ground yet suffer when its roots are exposed in a container or its crown remains wet.
Timing also matters. Preparing before a frost forecast gives gardeners time to move pots or set up breathable barriers, while overly early or tight wrapping can hold warmth and moisture against a plant. For hydrangeas, protection can affect next season’s flowers even if the shrub itself survives. The report’s recommendations are general guidance, not a guarantee of survival; local climate and cultivar can alter what is needed.

Why October Preparation Matters
The report frames October as a time to inspect plants and follow the local forecast. Its advice is to prepare ahead of the first hard frost, while reserving some measures for later: mulch after the soil begins to cool, and protect dormant hydrangeas once temperatures are consistently cold. That distinction is intended to avoid covering plants too early.
It gives broad U.S. Department of Agriculture hardiness-zone ranges for some plants, while stressing that varieties and local conditions differ. The listed examples include English lavender in Zones 5–9, coral bells commonly in Zones 4–8, bigleaf hydrangeas often in Zones 5–9, rosemary in sheltered parts of Zones 7–10, and established Japanese maples often in Zones 5–8. These ranges should not be read as guarantees for every cultivar or site.

Local Conditions Shape Plant Risk
The source material supplied here is incomplete: it cuts off in the gardenia entry and does not include the full descriptions for all eight plants. The complete list and any additional plant-specific instructions cannot be verified from the provided text. The report also does not identify a single frost date or climate region to which its October timing applies.
Exact protection needs depend on species, cultivar, site and forecast. Zone ranges are broad guidelines, and the material does not quantify how much protection changes survival rates. Gardeners should check plant-specific guidance and local forecasts rather than treating the recommendations as universal.
Prepare as Frost Approaches
Gardeners can begin by checking the forecast, clearing moisture-holding debris from lavender crowns, confirming drainage and identifying pots that can be moved to shelter. As soil cools, a loose mulch around root zones may help; it should not cover the crowns of plants such as coral bells. Any fabric cover should be breathable and arranged to avoid pressing against foliage.
For hydrangeas and other plants whose protection depends on dormancy, the report advises waiting for consistently cold conditions before adding winter cover. The next steps will vary with local weather and the plant’s variety. The supplied source gives no follow-up announcement or forecast, so the timing of frost and any further guidance remain unknown.
Key Questions
Which plants does the report identify as needing winter protection?
It names lavender, coral bells, bigleaf hydrangea, rosemary, Japanese maple, gardenia and evergreen shrubs, and discusses container-grown plants as a vulnerable group. The supplied source text is truncated, so the full eighth entry and complete list wording cannot be confirmed.
When should gardeners start preparing?
The report points to October as a time to check the local forecast and prepare before hard frost. Some measures, such as adding mulch, are recommended after the soil cools; hydrangea protection should wait until the shrub is dormant and temperatures are consistently cold.
Why might lavender need winter protection if it is considered hardy?
The report says cold, wet conditions and poor drainage can be more harmful than a brief freeze. It advises clearing damp debris from the crown and improving drainage rather than wrapping the plant tightly.
Should all hydrangeas be wrapped for winter?
No. The advice focuses on bigleaf hydrangeas that set flower buds on old wood, which severe cold can damage. The report says gardeners should check the variety; hydrangeas that bloom on new wood do not need the same bud protection.
