How to Overwinter Wintergreen

Wintergreen is resilient and withstands low temperatures well, making it ideal for winter landscapes.

Trimming Wintergreen plants assists in preserving their form and vitality during the colder season.

Applying mulch is vital for shielding Wintergreen roots from extreme cold and freezing injury.

Winter Requirements for Wintergreen

As an evergreen shrub, Wintergreen is remarkably resilient and can endure freezing temperatures, making it an excellent addition to gardens in colder climates. However, despite its toughness, specific conditions are needed to ensure its survival through winter. Firstly, it requires well-drained soil to prevent root decay from excessive moisture. Additionally, while Wintergreen doesn't demand frequent watering in winter, it does benefit from occasional hydration, especially if the soil is dry on a warmer winter day. Its natural habitat in shaded or partially shaded areas means it prefers similar conditions during winter, avoiding direct, intense sunlight.

Preparing Wintergreen for Winter

Pruning and Cleaning Up

Before winter arrives, it's crucial to prune and tidy up your Wintergreen plant. This involves removing any dead or diseased branches to stop the spread of illness and promote new growth in spring. Pruning also helps maintain the plant's shape and improves air circulation, reducing the risk of fungal problems. Make sure to use clean, sharp pruning shears and make precise cuts to avoid harming the plant.

Mulching and Soil Care

Mulching is a vital step in preparing Wintergreen for winter. Applying a 5-10 cm (2-4 inches) layer of mulch around the plant's base helps insulate the roots, protecting them from freezing temperatures. Organic mulches like pine needles, shredded leaves, or compost are excellent choices. Mulching also helps retain soil moisture and prevents rapid temperature changes that could stress the plant. Furthermore, ensure the soil remains well-drained by avoiding overly dense or compacted soil.

Protecting Wintergreen from Extreme Cold

Covering and Wrapping Techniques

In regions where temperatures drop severely, extra protection for Wintergreen may be necessary. Covering plants with burlap or horticultural fleece can provide a protective barrier against harsh winds and extreme cold. Ensure the coverings do not directly touch the foliage, as this can cause damage; instead, use stakes to create a tent-like structure.

Using Windbreaks

Windbreaks can be very effective in shielding Wintergreen from freezing winds that can cause desiccation. You can create windbreaks using materials like woven plastic, burlap, or even by strategically planting other shrubs and trees around your Wintergreen. This barrier helps to reduce wind velocity, thereby minimizing the stress on your plants.

Common Issues with Overwintering Wintergreen and Solutions

Frost Damage

Even though Wintergreen is frost-hardy, severe frost can still cause damage, particularly to younger plants. If you notice frost damageâsuch as blackened or wilted leavesâtrim off the damaged sections in spring to encourage healthy new growth. Ensuring a thick layer of mulch before frost can also mitigate this issue.

Pest Control

Pests like voles and rabbits may target Wintergreen during winter due to the scarcity of food. Using a physical barrier like chicken wire around the plant base can deter these creatures. Additionally, applying natural repellents or setting traps around your garden can help keep pests at bay.

Disease Management

Wintergreen can occasionally suffer from fungal diseases, especially if it has been overly wet. To manage diseases such as leaf spot or root rot, ensure proper airflow around the plant and avoid waterlogging the soil. In case of disease, remove and dispose of the affected plant parts promptly and consider using an appropriate fungicide.
