What to grow in December 2017

With Christmas and holidays on the horizon, many of you won’t have a lot of time to spare for gardening, or even watering the garden. Setting up some shade for your garden beds now, will provide protection in the hottest part of the day during summer’s hot weather, and prevents sun-scald of fruits and vegetables. A shade cover also reduces the amount of watering you need to do as it traps humidity around the plants and prevents wilting in extreme heat. See:
Sun and heat protection
For those who have a some time to spare this busy month, the following gardening advice is an abbreviated list for vegetables, fruit trees and some culinary herbs that can be sown or planted during December in Australia and New Zealand. A comprehensive guide that includes planting times for the entire garden, as well as when to fertilise, prune, take cuttings or divide plants, can be found in the diary section of my book Easy Organic Gardening and Moon Planting (Scribe Publications, 2017 with moon planting to 2022), and e-book (Bookish 2012).
* For gardeners who do not use moon planting: sow or plant out any of the following list for your climate zone at any time this month, although you may find germination rates are lower when the Moon is in Last Quarter phase.

WARM CLIMATE ZONES
If your area has a wet season in the next few months, it might be wiser to not sow sweet corn this month, as heavy rain will prevent good pollination. Corn of any variety can be sown as a green manure crop, though, because green manure plants are cut down when about knee high.

Before the Full Moon, silver beet, nasturtium and sunflower can be sown directly into beds, as well as a green manure crop of adzuki bean, cow pea, lablab, mung bean, pigeon pea, soybean, Japanese millet, millet, or sorghum.
During First Quarter phase, bush and climbing beans, eggplant and pumpkin can be sown directly into beds, and capsicum, rock melon, summer squash, tomato, watermelon and zucchini can be sown or planted out.
