Frost can be a gardener's worst enemy, especially in the colder months. Depending on where you’re located in Australia, our mornings can usually get quite chilly. Frost can damage or kill your plants, reduce your harvest of fruit and vegetables, and ruin all your hard work. Fortunately, there are some ways to protect your garden from frost and keep it healthy and productive. Here are some tips on how to prevent frost damage and prepare your garden for the winter.
Mulching
One of the best ways to protect your garden from frost is to apply a thick layer of mulch around your plants. Mulch is any organic material that covers the soil and helps retain moisture, regulate temperature, and suppress weeds. Mulch can also insulate your plants from the cold and prevent the soil from freezing. Some examples of mulch are straw, hay, leaves, wood chips, or compost. You should apply about 2 to 4 inches of mulch around your plants in late autumn or early winter before the low temperatures set in. If you haven’t applied any by the time winter arrives, don’t worry, you can still benefit from applying mulch even after the cold has arrived.
Feeding Your Plants
Feeding your plants with organic fertilizers that boost their immunity and resilience is a great way to protect your plants and flowers from frost. Feeding your plants can help them grow stronger and healthier, and cope better with stress and disease. Some examples of organic fertilizers are compost, manure, worm castings, or seaweed products. Seaweed products are especially beneficial for frost protection, as they contain natural hormones and minerals that stimulate plant growth and enhance root development.
You should feed your plants with organic fertilizers in late summer or early autumn before the lower temperatures and frost arrive. You can also apply a foliar spray of seaweed products every few weeks during the winter to provide extra protection.
Covers
Another way to protect your garden from frost is to cover your plants with frost cloths, blankets, shade cloths, or plastic tarps. Covers can create a barrier between your plants and the cold air and trap some heat from the soil and the sun. Covers can also prevent frost from settling on your plants and causing damage.
The ideal time to cover your plants is in the evening before the temperature drops too low and then remove them in the morning when the sun comes up. You should also make sure that the covers are not touching your plants directly, as it could potentially transfer the cold or moisture to them. You can use stakes, hoops, trellis, or cages to support the covers and create some space around your plants to avoid this.

Greenhouse Tunnels
Greenhouse tunnels can be used over your garden beds to protect them from frost. Greenhouse tunnels are structures made of metal or plastic hoops covered with clear plastic sheeting. Greenhouse tunnels can create a mini greenhouse effect over your garden and raise the temperature by several degrees. Greenhouse tunnels can also protect your plants from wind, rain, and pests.
You should aim to build greenhouse tunnels in late autumn or early winter before the low temperatures begin. You should also vent the tunnels on sunny days to prevent overheating and condensation from building up on your plants.
