NICKI'S GUIDE FOR JUNE IN THE GARDEN
Winter has officially arrived, and it certainly feels like it in Waihi. After the stunningly dry and warm month of May, June has arrived with a wet and blustery bang. With the Winter Solstice just around the corner, our window for sowing and planting outdoors is closing. It's a natural time to slow down, pause, and take stock.
June is ultimately about protection and care. Protect your soil, preserve its structure, and prevent nutrients from washing away. Mulch generously - vegetable beds with hay, straw, chopped leaves, or seaw**d, and woodchip through the orchard and along pathways.
Make compost and tidy the garden without "cleaning everything up". Leaves and plant material provide habitat for beneficial insects, while roots left in the soil continue to feed microbial life. Clear old crops by cutting them off at the base and leaving the roots to decompose. Minimal soil disturbance helps keep underground ecosystems healthy. Prune back spent crops, deadhead flowering plants, and get those compost piles going.
To keep harvests ticking over, stagger your plantings. In June, you can still sow:
Veggies – broad beans, broccoli, cabbage, cauliflower, kale, onions, spring onions, radishes, silverbeet, spinach, parsley, rosemary, sage, thyme and, in the greenhouse, beetroot, Asian greens, celery, lettuce, coriander, mizuna and rocket.
Companion flowers – alyssum, borage, calendula, cornflowers, stock, violas and poppies. These add winter colour while supporting pollinators and beneficial insects.
Now is also a good time to plant asparagus and rhubarb crowns. Strawberry runners can be potted up or planted out to refresh older patches and maintain productivity.
Garlic growers, if you haven't already, get those cloves in now. Plant your largest cloves into free-draining, compost-rich soil and mulch generously - garlic doesn't like w**d competition. Feed regularly to encourage strong bulb formation. I feed mine fortnightly with Ocean Organics NZ NZ Foliar Concentrate particularly in the early months.
If you're growing fewer edibles over winter, sow cover crops such as mustard, peas, oats, lupins, or broad beans. They suppress w**ds, improve soil structure, support microbial life, and legumes will also fix nitrogen for future crops. Broad beans and lupins are my go-to cover crops for beds destined for tomatoes in spring.
June is also an excellent time to plant deciduous fruit trees. Stake young trees if needed, mulch well with woodchip, and feed with compost. Pick up and compost any fallen or rotting fruit to help prevent disease carryover.
When pruning, remove damaged or diseased wood first, then shape the tree to improve light pe*******on and airflow. Sterilise tools between trees and only use copper sprays if fungal issues are present. Otherwise, focus on maintaining tree health with compost, mulch, and seaw**d foliar sprays.
Seed catalogues are my winter gardening fix when all else is said and done.
