Covers are most useful for frost—not a guarantee against severe or prolonged freezes.
Which plants need winter protection?
Start with the forecast and the plants most exposed to it. Give attention first to tender annuals, vegetables, tropical plants and vulnerable container plants when frost or a freeze is expected. A plant’s cold tolerance depends on its species and on how low and how quickly temperatures fall, so check local hardiness guidance for a particular plant rather than relying on one garden-wide rule.
Iowa State University Extension and Outreach says established perennials and woody plants generally do not need or benefit from protection in its regional guidance; many need cold to enter dormancy and tolerate temperatures near freezing with little damage. That advice is not universal across species or climates.
Use the site to reduce cold exposure
Look for low spots where cold air settles, open areas exposed to wind, and sheltered locations near buildings, fences or evergreen plantings. UGA Cooperative Extension notes that north and northwest sides and low areas are often colder, while southern exposures and nearby structures or larger plants can create warmer microclimates. A windbreak can reduce exposure to cold winds.

- Product Features: Our plant covers are ideal for protecting all plant. Made from premium 1 oz/sq non-woven fabric, their durability and breathability ensuring both insulation against frost and facilitation of sunlight penetration for healthy plant growth
- Versatility: These covers serve triple duty as frost protection, snow protection, animal barriers, insect barriers, and sun shields, adaptable to various gardening needs, the versatile row covers promise a tailored fit for all horticultural necessities
- Usability: Users can cut the frost blanket according to the size of the plant, and then easily cover the plant blanket directly on the plant, lay the cover loosely over plants, or fix it with the help of hoops or frames, providing customizable protection
- Cold & Wind Protection: Shield delicate plants from wintry chills and harsh winds, safeguarding them from frost damage. Regulate sunlight exposure to prevent overheating, maintaining optimal growth conditions. Maintain stable soil temperatures
- Optimize Performance: Deploy the covers before sunset to harness residual warmth from the soil. Once morning temperatures rise above freezing, remove the covers to permit sunlight warming. Wet covers should be dried before reuse
Keep the plant’s light requirements in mind when choosing a sheltered spot; moving a sun-loving plant into deep shade may trade one problem for another. For future plantings, choosing plants suited to local hardiness, soil, drainage, light and wind conditions is a long-term way to reduce winter risk.
Protect roots in the ground and in pots
In-ground plants: mulch the root zone
Mulch moderates soil heat loss and temperature swings around roots. Maryland Extension’s September 16, 2025 guidance describes about three inches as generally sufficient. Keep mulch around the root zone rather than piling on an excessive layer: too much can impede water movement through soil and limit oxygen. Mulch protects roots; it does not shield exposed leaves and stems from every freeze.

Container plants: shelter or insulate
Roots in pots are more exposed to cold than roots in the ground. When feasible, move containers into a suitable protected space such as a house, garage, greenhouse or shed. Choose a location that suits the plant’s light and temperature needs.
If a pot must stay outdoors, group it with other containers in a sheltered spot and insulate the sides with mulch, burlap or blankets. After the cold event, give crowded plants room again if they were packed together; prolonged crowding can damage some foliage.

Cover foliage when frost is forecast
A sheet, blanket, cardboard box or commercial frost cloth can help during a forecast frost. Support the cover above the foliage so it does not rest on leaves, and extend it to the ground where practical to retain warmth from the soil. Remove it or ventilate it on sunny days so heat does not build up underneath.
Plastic sheeting is not a set-and-forget substitute: foliage touching plastic can be injured, and plastic can heat rapidly. Iowa State University Extension and Outreach says covering is typically no longer effective at preventing cold damage once temperatures fall below about 28°F; it also cautions that a prolonged subfreezing period can cause damage even above that point. This is Iowa State’s practical regional guidance, not a universal rating for every plant, cover or climate.

Plant covers freeze protection are perfect for protecting yard trees, shrubs, potted plants such as banana trees, palm trees, olive trees, tree ferns, rose bush, apple/orange/lemon/citrus/blueberry trees, etc
Water according to soil conditions
Plants still need water in winter, but in-ground plants generally need it less often than in summer. Before a cold snap, check whether the soil is dry enough to need water. Moist soil can absorb and reradiate more heat than dry soil, but prolonged saturation can damage roots, so there is no universal pre-freeze watering amount or schedule.
Outdoor pots may dry faster than garden soil. After a freeze, check the soil or potting mix as well as the plant: frozen water may be unavailable to roots even when foliage is losing water on a sunny or windy day. Do not rely on a home irrigation system running continuously as freeze protection; UF/IFAS says ordinary home systems are not designed to deliver the quantities required for that method.

Wait before pruning suspected cold damage
Cold injury can take days or weeks to become clear. UGA Cooperative Extension recommends waiting several days after a freeze before checking buds and stems. If damage is uncertain, UF/IFAS advises delaying pruning until new growth appears and the threat of cold has passed, so viable wood is not removed prematurely. Black or brown tissue under the bark can indicate injury, but one inspection may not reveal the full extent.
Quick Recap
Choose a method that fits the risk
| Method | Best fit | Key limitation |
|---|---|---|
| Suitable plant and site | Reducing winter risk across the garden over time | Must fit local hardiness, soil, drainage, light and wind conditions. |
| Root-zone mulch | Moderating soil temperature around in-ground roots | Does not cover exposed foliage; excessive mulch can impede water movement and oxygen. |
| Move a container under shelter | Potted plants facing a freeze | Requires a suitable protected space; plants differ in light and temperature needs. |
| Insulate pot sides | Outdoor pots that cannot be moved | Helps protect exposed roots but does not make a tender plant freeze-proof. |
| Supported sheet, blanket or frost cloth | Temporary protection from forecast frost | Must be supported and removed or ventilated; protection declines in severe or prolonged cold. |
| Water based on need | Dry soil before a cold snap or checking frozen soil after a freeze | Avoid waterlogging; needs vary with drainage, rain and container conditions. |
