Sow in November–December after 7–10 days of day temperatures consistently above 20°C and night temperatures above 10°C.
Sow shallow at a depth of about 10 mm (half an inch).
Although the soil surface may be dry, use a push-probe to ensure that there is at least 1 m of subsoil moisture at sowing.
Sowing after the end of January is generally not recommended since plants will be too small to withstand frosting in the subsequent autumn, winter and spring.
