What vegetables can I plant in December in Perth?
December in Perth 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 Perth 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 Perth?
Watering frequency depends on your soil type and weather. In December in Perth, 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.
What soil improvements help Perth gardens in December?
Perth's sandy soils drain fast and hold few nutrients. Add compost, aged manure, and worm castings regularly to build organic matter. Bentonite clay mixed into sandy soil improves water retention. Use wetting agents if your soil becomes hydrophobic. Raised beds with imported soil mix give the best results for vegetables.
