What vegetables can I plant in December in Adelaide?
December in Adelaide is summer, so focus on crops suited to Mediterranean 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 Adelaide 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 Adelaide?
Watering frequency depends on your soil type and weather. In December in Adelaide, 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.
How do I manage water restrictions when gardening in Adelaide in December?
Adelaide's water restrictions vary by season. Use drip irrigation and soaker hoses to water efficiently. Mulch beds heavily with straw or lucerne to reduce evaporation. Consider installing a rainwater tank and using greywater on ornamentals. Wicking beds are excellent for growing vegetables with minimal water.
