Gardening Checklist for April in New Zealand
April marks the middle of autumn in New Zealand, and it’s a crucial time to prepare your garden for the cooler months ahead. Here’s a comprehensive checklist to help you maintain your garden and get it ready for winter.
General Garden Maintenance
- Weeding: Regularly remove weeds to prevent them from competing with your plants for nutrients and water.
- Mulching: Apply mulch around plants to conserve moisture, suppress weeds, and insulate roots from the cooling temperatures.
- Cleaning: Clear away fallen leaves and plant debris to prevent pests and diseases. Add healthy organic matter to your compost pile.
- Tool Maintenance: Clean, sharpen, and oil your garden tools to prepare them for the winter months.
Vegetable Garden
- Planting: Plant winter crops such as garlic, onions, shallots, and broad beans. Sow seeds for leafy greens like spinach, kale, and lettuce.
- Harvesting: Harvest the last of your summer crops, including tomatoes, peppers, and pumpkins. Continue harvesting winter vegetables as they mature.
- Cover Crops: Sow green manure crops like lupins, mustard, or oats to improve soil health and fertility for the next growing season.
- Feeding: Apply a slow-release fertilizer to winter vegetables to support their growth during the cold months.
Fruit Garden
- Pruning: Prune deciduous fruit trees such as apples, pears, and stone fruits after they finish fruiting. Remove dead, diseased, or crossing branches to improve airflow and shape the tree.
- Planting: April is a good time to plant new fruit trees and bushes. Ensure they are well-watered and mulched to help them establish before winter.
- Protecting: Use frost cloth or covers to protect vulnerable fruit trees and plants from frost damage.
- Feeding: Apply a balanced fertilizer to fruit trees and bushes to support their health and future fruit production.
Flower Garden
- Planting: Plant spring-flowering bulbs such as daffodils, tulips, and crocuses. Also, plant winter annuals like pansies, violas, and primroses for some color during the colder months.
- Pruning: Prune roses and other deciduous shrubs after they finish blooming to shape them and remove dead or diseased wood.
- Deadheading: Remove spent flowers from annuals and perennials to encourage further blooming and maintain a tidy appearance.
- Dividing: Divide and replant overcrowded perennials such as irises, daylilies, and hostas.
Lawn Care
- Mowing: Continue to mow the lawn, but gradually raise the mower height to leave the grass slightly longer for winter protection.
- Feeding: Apply a slow-release autumn lawn fertilizer to strengthen the grass and prepare it for winter.
- Aerating: Aerate the lawn to improve drainage and reduce compaction, especially in areas with heavy foot traffic.
- Weeding: Remove weeds by hand or use a selective herbicide to keep the lawn looking its best.
Container Gardening
- Watering: Check containers regularly and water as needed, ensuring the soil is not waterlogged. Reduce watering frequency as temperatures drop.
- Feeding: Use a slow-release fertilizer or liquid feed for container plants to support their growth during the cooler months.
- Protection: Move containers to sheltered spots to protect plants from frost and cold winds. Use frost cloth or covers if necessary.
- Re-potting: Re-pot container plants that have outgrown their pots or need fresh soil.
Herb Garden
- Harvesting: Harvest herbs such as basil, parsley, and mint before the first frost. Dry or freeze herbs for winter use.
- Protection: Move tender herbs like basil and rosemary indoors or to a greenhouse to protect them from frost.
- Planting: Plant cold-hardy herbs such as thyme, sage, and oregano in the garden or containers.

By following this comprehensive gardening checklist for April, you can ensure your garden remains healthy and well-maintained as you transition into winter in New Zealand.
