As the colder weather approaches, now is the time to take steps to protect your garden, ensuring the survival of your plants through the winter months. Emma O’Neill, head gardener of the horticultural charity Garden Organic, provides valuable advice on preparing your garden for the first frosts.
One important tip is to mulch flower beds and borders with homemade compost to protect plant roots from freezing temperatures and improve soil structure. Pruning roses by one-third to one-half can reduce the risk of wind rock, preventing frost damage to the roots. Leaving stems on tender perennials and flowerheads on shrubs like hydrangeas can offer protection and add visual interest to your garden during winter.
For plants in patio pots, remember to use pot feet to prevent cracking due to frost. Avoid feeding pot plants and stop watering them to prevent frost damage to delicate new growth. Move tender potted plants to frost-free areas or wrap them in horticultural fleece. Winter crops like garlic and onion sets should be planted now, with cloches used to shield winter salads from harsh weather.
Checking ponds and preventing them from freezing completely over is essential to maintain oxygen levels for wildlife such as fish, frogs, and toads. Sowing green manures like fenugreek and crimson clover before the end of October can protect the soil and add nutrients for the upcoming season. These green manures can also nitrogen-fix the soil and limit weed growth, especially in vegetable gardens.
By following these tips and being proactive in protecting your garden before the arrival of the first frost, you can ensure the health and vitality of your plants throughout the winter months. With careful planning and attention to detail, your garden can thrive despite the challenges of the colder season.
