As the cooler months approach, preparing your garden for winter is essential to ensure it remains healthy and productive. A well-maintained garden can withstand harsh conditions and bounce back stronger in spring.

This guide provides practical steps to get your New Zealand garden ready for winter, focusing on seasonal tasks and sustainable practices.

Clean Up Your Garden

  1. Remove Dead Plants: Clear out any dead or diseased plants to prevent pests and diseases from overwintering.
  2. Weed Thoroughly: Remove weeds to stop them from competing with your plants for nutrients and space.
  3. Tidy Up Borders: Trim back overgrown plants and rake fallen leaves to keep your garden supplies tidy and reduce the risk of fungal diseases.

Protect Your Soil

  1. Apply Mulch: Spread a layer of organic mulch, such as straw, bark, or compost, over your garden beds. Mulch insulates the soil, retains moisture, and suppresses weeds.
  2. Cover Crops: Plant cover crops like clover or rye to improve soil fertility and structure while preventing erosion.
  3. Avoid Compaction: Limit walking on wet soil to prevent compaction, which can restrict root growth and water infiltration.

Prepare Your Plants

  1. Prune Deciduous Trees and Shrubs: Remove dead or damaged branches to promote healthy growth in spring.
  2. Protect Tender Plants: Move potted plants indoors or to sheltered areas, and cover delicate outdoor plants with frost cloths or hessian.
  3. Divide Perennials: Dig up and divide overcrowded perennials to rejuvenate them and create new plants for next season.

Maintain Your Lawn

  1. Aerate the Soil: Use a garden fork or aerator to improve drainage and reduce waterlogging.
  2. Fertilise: Apply a slow-release fertiliser to strengthen grass roots and prepare your lawn for winter dormancy.
  3. Mow Strategically: Keep your lawn slightly longer during winter to protect it from frost damage.

Winter-Proof Your Tools and Equipment

  1. Clean and Store Tools: Wash, dry, and oil garden tools to prevent rust. Store them in a dry, sheltered location.
  2. Service Equipment: Check and service lawnmowers, trimmers, and other equipment to ensure they are ready for spring.
  3. Protect Irrigation Systems: Drain and store hoses and irrigation systems to prevent damage from freezing temperatures.

Plan for Next Season

  1. Plan Your Spring Garden: Use the winter months to research and plan what you’ll plant in spring.
  2. Order Seeds and Supplies: Stock up on seeds, fertilisers, and other gardening essentials.
  3. Build New Garden Beds: Use the quieter season to construct new raised beds or garden structures.

Sustainable Practices for Winter Gardening

  1. Compost Organic Waste: Turn garden waste into nutrient-rich compost to use in spring.
  2. Harvest Rainwater: Set up rain barrels to collect and store water for future use.
  3. Encourage Wildlife: Install bird feeders or insect hotels to support beneficial wildlife during winter.
