A Homes & Gardens gardening report recommends covering winter brassicas with netting raised on hoops or posts, securing the edges, and staking tall plants against wind. The article says many brassicas tolerate frost, but hardiness varies by variety and climate; growers in colder zones may need thicker frost cloth.
A Homes & Gardens gardening report recommends protecting kale, cabbage and other winter brassicas with netting raised over hoops or posts, while staking taller plants to limit wind damage. The advice addresses two risks to overwintering crops—wildlife feeding and plants being loosened or toppled by strong winds—while noting that frost protection needs vary by crop variety and local climate.
The report says netting can keep birds and other animals from reaching the leaves while allowing light and water to pass through. Birds may peck holes in foliage or strip plants, while rabbits, deer and rodents can also feed on brassicas. Slugs and snails may remain active during winter. Fine insect mesh used earlier in the growing season can, according to the report, be left in place as a barrier against some cold-season pests.
Netting should be supported by hoops or posts, rather than placed directly on the crop. The article warns that animals may reach leaves through material lying against them, and that netting can freeze onto plants on frosty nights. It advises securing the edges with landscape staples or bricks so wildlife cannot get underneath and wind cannot lift the cover.
For tall crops such as Brussels sprouts, broccolini and some kale varieties, the report recommends tying the main stem to a bamboo or wooden stake with a soft, flexible tie. This is intended to reduce wind rock—the movement of plants that can loosen roots—and the risk of plants falling over. The article also notes that frost cloth may be appropriate in colder growing zones, depending on the crop and conditions.
Protecting Crops Through Winter
Winter harvests can be lost even when a crop is considered hardy. Wildlife damage and strong winds can affect leaves, roots and plant stability, while severe cold may injure crops and reduce the harvest. The report’s approach is practical because it separates these problems: netting forms a physical barrier to animals, and staking supports plants exposed to wind.
The advice also cautions against treating all brassicas or gardens alike. A cover that works as a pest barrier may not provide enough insulation during a severe freeze. Gardeners need to account for variety, local climate and the type of threat rather than assume that a single covering method will prevent every kind of damage.

Hardiness Depends on Crop and Climate
Kale, winter cabbage, cauliflower and Brussels sprouts can be grown through winter in some gardens. The report says frost may make some brassicas taste sweeter, but cold tolerance does not mean plants are immune to damage. It gives examples of hardiness ranges: some of the hardiest kales may tolerate temperatures down to -10°F, while savoy winter cabbages and Brussels sprouts may tolerate about 10°F. These figures are presented as examples, not guarantees for every variety.
The article says growers in USDA hardiness zone 5 can often overwinter these crops without major concern about cold damage, while gardeners in zones 3 or 4 may need hardier varieties and thicker frost cloth. It also points out that snow can insulate plants in cold northern areas, although snow cover can make harvesting more difficult. The source does not identify a specific garden or report measured results from a trial.

Limits of the Winter Protection Advice
The source does not provide a publication date, identify a particular garden where the advice was tested, or quantify how much netting or staking reduces crop losses. It also does not specify a single frost-cloth thickness for every climate or brassica variety. The temperature tolerances cited are approximate examples, and actual cold hardiness varies by variety and conditions.
Netting is described as a barrier to birds and other pests, but its effectiveness will depend on mesh size, how securely the edges are fastened and which animals are present. The report does not say that covers prevent all pest damage or eliminate the risk of frost injury.
Match Covers to Local Conditions
The report offers general garden guidance rather than a scheduled next development. Gardeners following it would need to check the hardiness of their specific varieties and local winter conditions, then choose between pest netting, frost cloth or both as needed. Covers should be supported and anchored, and tall plants should be tied to stakes where wind exposure is a concern.
There is no announced follow-up, new study or planned update in the source material. Any assessment of how well the measures worked would depend on the garden’s weather, crop varieties and pest pressure over the winter.
Key Questions
What is the recommended way to protect winter brassicas from birds?
The report recommends bird-proof netting supported by hoops or posts. It says to secure the edges with staples or bricks so birds cannot get underneath.
Should netting sit directly on kale or cabbage?
No. The article advises raising netting above the plants. Animals may reach leaves through material resting on the crop, and on frosty nights netting may freeze onto vegetables.
Do winter brassicas need frost cloth?
Not necessarily. The report says many brassicas can overwinter outdoors, but cold tolerance depends on variety and climate. It suggests that gardeners in colder zones, particularly zones 3 or 4, may need hardier varieties and thicker frost cloth.
Why stake Brussels sprouts and tall kale?
Staking can steady tall plants in strong winds. The report says wind rock may loosen roots, and severe movement can topple a plant.
