NICKI'S GUIDE FOR DECEMBER IN THE GARDEN
Summer has officially arrived, and with it comes the busy rush of the festive season. It’s easy to let the garden slip down the priority list, but regular check-ins will pay dividends.
Most of your main summer crops should already be planted. Make sure taller crops are well supported - especially tomatoes. On a dry day, remove the laterals (the shoots that grow between the main stem and a leaf) to boost airflow and prevent overcrowding. Climbing beans will need a trellis or teepee to scramble up, while bush beans can be tucked into any spare pockets of space. Keep sowing a few every couple of weeks.
Zucchini, cucumbers, melons, sweetcorn, pumpkins and squash should all be in by now - keep them mulched and watered. Chillies, capsicum and eggplants can still go out in a sunny spot. In the orchard or food forest, you can plant rhubarb, grapes, passionfruit and tamarillo.
From here, it’s all about small, steady actions. Successive planting every 3-4 weeks keeps the harvests flowing: mizuna, rocket and coriander (in shady spots), Asian greens, basil, beans, lettuces, beetroot, parsley, spring onions, silverbeet, spinach, radishes, cucumbers and even another zucchini or two. There’s still time for strawberries, kūmara and potatoes.
For flowers, amaranth, bishop’s flower, poppies, nasturtiums, cosmos, sunflowers, echinacea, zinnias, calendula, marigolds, cornflowers and salvias, all boost pollination and add colour.
Mulching is essential - use close plantings, pea straw, seaweed, untreated sawdust or homemade mulch to conserve moisture, block weeds and protect soil life. Stressed plants (too dry or too wet) are more disease-prone, so use your finger as a moisture gauge and skip watering if the soil is still damp.
Watch for stink bugs, aphids and other pests - squish on sight. A three-weekly neem spray helps, but diversity and allowing some plants to flower and seed will bring beneficial insects (like ladybirds who can eat up to 50 aphids in a day!). Keep up the seaweed foliar sprays as a preventative measure
And finally - keep picking! Harvesting encourages fresh growth. Fossick for new potatoes, and check onions and garlic; when about half the leaves are brown, harvest time is close. Keep an eye on tomatoes, zucchini and beans; they’ll start appearing overnight before you know it!
My next Edible Gardening Workshop will be held on the 21st Feb.
Wishing you a safe, sunny and joyful festive season.
