I've been gardening since childhood and used to grow lettuce easily as a kid. However, I'm having trouble getting my lettuce seeds to germinate now. I've tried everything and I'm sure the seeds are good. I live in the southern hemisphere, where it's currently late Autumn and mostly frost-free. I've had success with other leafy greens, but lettuce is just not working for me. Any tips would be greatly appreciated; I'm getting a bit desperate over here!

I'm curious about how you're planting them! If you're covering them with too much soil or letting them dry out, that could be the culprit. When I had issues, moving to seed starting indoors helped a ton!
I've had way more success starting lettuce in six-cell trays instead of direct seeding. It just makes it easier to manage and ensures they don't get eaten by birds or ants. I use premoistened potting mix, drop a couple of seeds in, and cover them lightly with vermiculite which helps keep them moist while still allowing light in. Once they’re big enough, I transplant them into the garden as space opens up.
There are a few key reasons why your lettuce seeds might not be germinating. First off, make sure you’re not planting them too deep; they need light to sprout. Just give them a light dusting of soil and keep the area moist with daily misting. Also, ants might be carrying them off, so keep an eye out for that! If you haven’t already, try to ensure they stay moist, as they can dry out quickly. Lettuce does best at around 20°C too!
Have you tried starting them indoors? I find germination rates are much better that way. Outside, they can dry out quickly, especially if you’re not watering regularly. Another thing to consider is pests—maybe some critters are snatching them up before they have a chance to sprout!
Totally agree! I’d add that if they’re not kept moist, they won’t sprout. I've noticed they require a bit of extra care initially.
