What vegetables can I plant in December in Sydney?
December in Sydney is summer, so focus on crops suited to warm temperate conditions at this time of year. Check the full planting list above for every vegetable, herb, and fruit you can sow or transplant this month, with spacing and harvest timing included.
How do I keep my Sydney garden alive in the December heat?
Water deeply in the early morning before the heat sets in. Mulch beds 8 to 10 centimetres deep to retain moisture and cool the soil. Use shade cloth (30 to 50 percent) over leafy greens and lettuce. Prioritise heat-tolerant crops like sweet potato, okra, and beans.
How often should I water my vegetable garden in December in Sydney?
Watering frequency depends on your soil type and weather. In December in Sydney, check the soil moisture by pushing your finger 5 centimetres into the soil. If it feels dry, water deeply. Mulch reduces watering needs significantly. Most vegetable gardens need deep watering two to three times per week rather than light daily sprinkles.
Do I need to adjust my planting for coastal vs western Sydney in December?
Yes. Coastal Sydney stays a few degrees milder than western Sydney, which gets hotter in summer and cooler in winter. Western Sydney gardeners may need more shade protection in summer and can plant warm-season crops a week or two earlier in spring. Coastal gardens benefit from the moderating ocean breeze.
