As we move into the colder months, I am in the process of getting my garden ready for winter, ensuring it remains healthy. I have put together my go-to guide for winter gardening, so you can protect your plants, prepare your soil, and choose the right vegetables and maintenance strategies.
1. Soil and Plant Preparation: During late Autumn, I start by applying a 5cm thick layer of generic mulch around the plants to prepare to protect them. This not only prevents the plants from feeling the cold temperatures, but also helps to conserve moisture and add nutrients back into the soil.
2. Vegetable Garden Care: In my vegetable garden, I focus on planting robust winter vegetables that thrive in cooler temperatures. My go-to choices include broad beans, beetroot, broccoli, cabbage, celery, kale, garlic, onions, peas, shallots, silverbeet, spinach, and coriander. Quick tip: Garlic is best planted around the shortest day of the year, which is on Friday, June 21st this year in New Zealand.
3. Protecting Against Frost: Frost can be a significant concern, so I keep a frost cloth or tunnels handy to protect sensitive plants. I also like planting in containers, which allows me to easily move plants to sunnier spots during the day.
4. Fruit Garden Adjustments: Winter is the ideal time for planting new deciduous fruit trees. I always choose healthy seedlings and plant them in an enriched garden mix for the best start. I apply a thick layer of mulch around fruit trees to maintain soil moisture and temperature. Most deciduous fruit trees require pruning this season, and I use fungicidal sprays to control diseases like leaf curl.
5. Flower Garden Management: In my flower garden, I plant winter-resistant species such as calendula, nemesia, pansies, polyanthus, poppy, snapdragon, stock, and viola. Winter is also the best time to plant new roses because the plants are dormant, which reduces planting stress. I prune existing roses and perennials that look untidy or have finished flowering and apply compost and organic fertilisers to promote growth.
6. General Maintenance: I keep on top of weeding and apply mulch around plants to suppress weed growth and conserve soil moisture. I move frost-tender patio plants to sheltered positions to protect them from cold snaps.
If you share a passion for gardening like me, I hope you find these tips useful as we move into the winter months. Winter isn’t a time to pack away the gardening gear. If you prepare your garden correctly and choose the right plants, we can set a strong foundation for a thriving garden in Spring.
