How To Protect Your Garden From Pests During The Winter Months

Humans are not the only ones who get to enjoy winter. Many garden pests and diseases also thrive during the winter months causing serious harm to our gardens. There are a variety of plants and flowers that can tolerate the cold weather but they often get infested by annoying insects. It is such a shame to allow these pests and diseases to destroy a garden that gives life to a home during dreary winter months. If you want to protect your garden during the winter and keep it healthy for the arrival of spring, then learning more about these pests and diseases and how to prevent them is your best solution.

Snails And Slugs

There are creatures that are able to survive the cold and snails and slugs are among them. They find shelter from the cold and remain dormant until the temperature rises a little. Though they may hide during the day, they come out at night in search for food when the weather is moist and cool. The best way to protect your garden from snails and slugs is by scattering crushed eggshells around your plants and flowers. You can also use copper tape around potted plants to keep these pests away as they avoid having their bellies come into contact with it. Another method is by applying salt or lime around the plants to effectively deter snails and slugs.

Root Rot

This is a common problem with plants during winter as it can make leaves turn yellow and plants wilt. If a plant is affected, it will be mushy and black, while the roots may fall off the plants. To get rid of root rot, simply take the plant and wash the roots, then trim the roots with a sharp scissor. Once clean and trimmed, you can replant it in a pot.


Aphids are a common problem in gardens and they can infest plants throughout the year so you must always keep an eye out for them. They can survive the colder weather by overwintering on hedgerows and ornamental plants without being seen until ants begin to infest the plants as well. The best way to keep aphids off your garden is by picking them off by hand to prevent them from multiplying. Another pest that can infest your garden similar to aphids is the Cabbage White Butterfly that overwinters in gates and fences.

Cutworms, Carrot Fly, Onion Fly And Beet Leaf Miner

If you have vegetables growing during the winter then you must be cautious about a handful of pests thriving in your garden as they can overwinter in the soil. The beet leaf miner, carrot fly, cutworms and onion fly can seriously damage your vegetables and make your garden look poorly cared for. To get rid of these pests during the winter, you can dig up the soil and expose them to birds and the cold weather. To protect your garden from carrot fly larvae, you need to dig up all the roots and burn the roots that have been infested.

Caring for a garden during the cold weather can be a challenge, but it is essential if you are determined to have a healthy garden next season. Since pests are the primary concern in a garden, it is better that you consult with a professional to determine the best treatment for your garden.
