Australian Yellow

Lettuce

55d to harvest

Sunlit and tender, Australian Yellow forms loose, airy rosettes with a buttery-gold glow and a crisp, succulent bite. The leaves are delicately ruffled and refreshingly mild, making them a standout for fresh salads and bright, quick tosses—ideal for gardeners who want color as much as crunch. Harvest at peak youth for the sweetest texture and a clean, leafy finish.

Frequently Asked Questions

Why are my Australian Yellow seedlings wilting or getting a slimy, brown stem near the soil line, and how can I stop it?

This is commonly stem rot or damping-off. Remove and discard the affected seedlings, then water only from the soil line and avoid wetting the foliage; improve airflow around the plants. Use fresh, well-draining seed-starting mix and consider a label-approved copper or biofungicide (follow the product directions) if damping-off keeps recurring.

During the main growing phase, how often should I water Australian Yellow to avoid stunting or splitting?

From when plants are established through the 40–55 day growth window, keep the root zone evenly moist—aim for the top 1 inch of soil to dry slightly before watering again. In part-sun beds, this typically means watering about 2–3 times per week during warm weather, but less if your soil stays cool or you have recent rain. Don’t let the soil swing from very dry to heavily soaked; that inconsistency can lead to poor development and uneven fruit.

How do I know when Australian Yellow is ready to harvest at around 55 days?

Harvest when the fruit has reached its full size and has turned a deep, even yellow color with a firm-but-not-hard skin. If the skin looks dull or stays pale, give it a few more days; if it turns patchy or starts to soften, pick immediately. For best flavor, harvest in the morning and avoid leaving fruit on the plant after it’s fully yellow.
