As winter descends, our gardens undergo a period of dormancy, with many plants drawing their energy inwards to prepare for the renewal of spring. However, even during this quieter season we can experience dry spells, and gardens still require some attention, especially when it comes to water. Whilst excessive watering can lead to root rot and other problems, proper winter watering during dry spells can help to ensure your plants emerge from their slumber healthy and ready to thrive.
Efficient Irrigation Techniques
The advice below is relevant for extended dry periods, use your gardener’s common sense as to whether watering is needed – and if it is, follow these tips. One of the most important principles of winter watering is to be efficient. Overwatering can lead to waterlogging, damaging roots and making plants more susceptible to diseases. Instead, focus on deep watering less frequently. This will encourage your plants to develop strong root systems that can reach deeper into the soil to access moisture even when rainfall is scarce.
A great way to achieve deep watering is to use a soaker hose or drip irrigation system. These systems deliver water slowly and directly to the root zone, minimising evaporation and maximising water utilisation. If you don’t have a soaker hose or drip irrigation system, you can still use a traditional watering can, but make sure to water deeply and avoid overhead watering, which can increase evaporation and spread diseases.
Rainwater Harvesting
Harvesting rainwater is an excellent way to conserve water and reduce the cost of your metered water supply. By capturing rainwater from your roof, you can use it to water your garden, wash your car – or even flush your toilets! There are many different rainwater harvesting systems available, from simple rain barrels to more complex installations. At the most basic end, a simple water butt will provide you with an abundant source of free water. Let water butts fill up in the rainy seasons to sustain your garden throughout the inevitable dry spells when the warm weather comes.
Mulching for Moisture Retention
Mulch is a layer of organic material, such as bark chips, leaves or compost, that is applied to the soil surface. Mulching through the winter helps to conserve moisture by preventing water from evaporating from the soil surface. It also helps to suppress weeds, regulate soil temperature, and improve soil structure. We’ve explained in this previous blog post how to use fallen leaves to create rich homemade mulch.
Choosing Water-Efficient Plants
When selecting plants for your garden, consider those that are naturally drought-tolerant. These plants have evolved to survive with limited water and will require less watering in the winter. Some examples of water-efficient plants include lavender, rosemary, sedum and succulents.
Watering Tips for Specific Plants
Whilst most plants require less water during the winter, there are some exceptions. Evergreen shrubs and trees, for example, may need to be watered more frequently to prevent their leaves from drying out. If you have these types of plants in your garden, you may need to water them once a week or even more often during extended dry periods.
Winter Watering: A Collective Effort
By following these tips, you can help conserve water and ensure that your garden remains healthy and thriving even during the winter months. Remember, every little bit helps! When we all take steps to conserve water, we can make a real difference in protecting our precious water resources for future generations.
