Victoria Lettuces can be planted year-round in Victoria, but the optimal time is during the cooler months, from early autumn to late spring (around March to November).
South Australia Similar to Victoria, lettuces thrive in the cooler months in South Australia. Sow lettuce seeds from early autumn to late spring (around March to November). Begin indoors and transplant seedlings outdoors when they are large enough to handle.
