Not all lettuce grows on the same timeline. Loose-leaf lettuce (like Black Seeded Simpson or Red Sails) is the Speedy Gonzales of the garden, often germinating in 2–4 days.
Romaine and butterhead types are a tad slower, taking 5–8 days. And the slowpokes? Crisphead (iceberg) varieties. They’re the “I’ll get there when I get there” type, needing up to 10 days. Still worth the wait, though—crunch is a virtue.
What if Nothing Happens? A Panic-Free Guide
Okay, so you waited 10 days. You sang to your pots. You wore a lettuce costume. And nothing. Don’t cry—it’s not you, it’s the seeds. Old seeds or bad storage are common culprits. Those little guys have a shelf life; after a year or two, they lose their mojo.
Another possibility: you overwatered. Soggy soil is a death sentence for seeds. They want oxygen, not snorkels. And if you planted them in scorching heat, well, welcome to the waiting game. Next time, chill the soil with a cold drink or shade cloth.
Finally, check for birds or hungry bugs. Sometimes they enjoy a seed buffet while you sleep. Rude, but fixable with a little row cover.
