Lettuce (let us) chill

Lettuces can be a funny one to try and germinate, albeit one of the easiest to grow once you’ve got them beyond this point. Therefore, we thought we’d given a step-by-step guide to how we sow our lettuces to get them germinated.

Most seeds require stratification before they will germinate. This is a process which imitates the natural process required for the seed to germinate. In the case of lettuces, this requires the seed to be chilled before it is left to germinate (hence the title of this blog post!)

To achieve this, we leave our lettuce seed in the fridge all the time. That means that they’re chilled whenever we want to sow them!

When we’re ready, we prepare a quarter seed tray. I know we’ve been through this before, but in case you’re a new reader (or just as a reminder!) that means filling the tray loosely with Seed and Modular compost, gently compressing this and then lightly watering with a fine rose watering can.

Then we scatter as many lettuce seeds as we want to grow in a quarter seed tray and cover with vermiculite. This time round, it was Little Gem.

We then place the seed trays under the bench and cover with a piece of glass and a couple of sheets of newspaper. This is to stop the light getting to the seeds whilst they’re trying to germinate.

These were sown last Monday, and by today they were ready to prick out! This is the seedlings after they’ve been pricked out into cell trays. They will stay in these cells until they’re ready to be planted out, which will probably be in a couple of weeks.
