It's autumn once more and like many gardeners, we're excited to make the most of this season by planting vegetables, flowers & herbs that can handle the colder months to ensure a steady supply of fresh vegetables throughout the colder months.
Now, it's time to preserve the surplus produce and prepare the garden beds for the colder months. The good news is that it’s also the time to freshen up the gardens with new flowering plants to encourage more pollinators and keep the vegetables producing.
Autumn is the best time to plant natives. The cooler temperatures reduce the stress on newly planted trees. This helps them develop stronger roots in preparation for the winter months. Autumn's rain offers a wonderful reprieve to the garden.
Garden maintenance
- Harvest the last of your summer crops. Preserve the excess produce by drying or pickling.
- Plant your brassicas and companion flowers that can handle the cold weather like alyssum, calendula, marigold.
- Plant long-living herbs like rosemary, sage, oregano, mint and thyme.
- Be on the lookout for slugs.
- Continue to tidy up the garden by trimming hedges, mowing the lawn, and weeding.
- Separate clumps of perennials.
- Add compost and organic fertiliser to replenish nutrients of the soil.
- Add a layer of mulch to help retain moisture in the ground.
Edible garden
- Brassicas, such as broccoli, cabbage, and cauliflower, thrive in this season. If you're looking for some variety, consider adding beets. You may also want to plant onions, carrots, or leeks where you previously had brassicas. Move the brassicas to a new bed with high-quality soil. If you have limited beds, it's a good idea to add a bit more compost.
- Crop rotation is beneficial in preventing or minimizing the risk of diseases and pests, as soil can become depleted and develop a buildup of disease-causing pathogens.
- Brassicas are heavy feeders and require well-draining, high-quality soil. Space brassica varieties about 50cm apart. If you have limited garden space, growing cabbages in containers (approximately 30-35 liter containers) could be an option. You may plant approximately 5 cabbages in a 35-liter container. Try planting spring onions in the same container as a great companion plant for cabbages. Containers may also be a good alternative for some frost-sensitive plants in areas with cooler climates, as they can be moved to areas with more sun or inside a greenhouse.
- If you have an abundance of tomatoes or zucchinis, it's a good time to start preserving them (e.g. tomato or zucchini relish).
- Fill your garden spaces with fast-growing lettuces to maximise garden space.
- Here are our recommended vegetables for your garden this autumn: Kale/Cavolo Nero, Pak Choy, Spinach, Lettuces, Rocket, Beetroot, Carrots, Celery, Kohlrabi and Brassicas (Broccoli, Broccolini, Cabbages, Brussel Sprouts, Cauliflower).
Flower garden
- Keep your flower garden blooming with beautiful, mildly fragrant stock flowers. They have stunning displays and are a perfect choice for cut flowers and indoor floral arrangements. Awapuni Nurseries have tall and short varieties available throughout autumn to create a layered look.
- Autumn is a time for edible flowers like pansies, violas, cornflower.
- Use flowers like alyssum, calendula and marigold to deter pests and encourage more beneficial insects to visit your garden.
Herb garden
Consider growing strong-smelling herbs such as thyme and sage, as they are useful companion plants for brassicas (broccoli and cabbages) as they help repel pests. Sage and thyme like mint, chives and oregano can handle colder climates. These herbs can be brewed to make soothing tea and can be added to main dishes for an extra burst of flavour.
Natives
- Autumn is the perfect time to plant a wider range of native plants. Natives enjoy the cooler breeze and appreciate wet weather. If you're in a warmer region of New Zealand and are considering planting natives now, place them in a sheltered area and water them regularly until more rain comes and the days become shorter.
- You may also want to consider starting your native hedges this season. Pittosporum, griselinia and ake ake varieties are fast-growing natives that are great for hedges. Whilst you can plant them at any time of the year, they would love a slightly warmer soil and the rain to get established more quickly.
- Flaxes are great options for erosion control if you have a river or stream flowing through your property.
