Lettuce

Worth a mention.

Lettuces like a good fertile soil, and don't let them want for water. A sure sign imo that they aren't happy, is when you get an 'open' habit, ie:- no heart. Not necessarily a bad thing, but it won't be as tender as it could be.

 

I've had four lettuces over-wintering in a window box - had some spare seedlings so I thought I'd give it a go.

Think they are going straight to seed as soon as the temperatures begin to rise!

 

I find they don't like the heat, so I sow a few every fortnight, for succession, but don't expect much during the heat of Summer.

 

I was going to mention that, but discounted good weather from the equation

 

It wouldn't hurt, imo. But not dark...

 

You're in for a shock then.

Although maybe not this year / decade ...

 

Whilst we are on the subject, too early to sow? Was thinking that I could start them off in the greenhouse, then plant them out under a cloche..

 

I do that. My "schedule" is to start 01-March. I also sow a few plastic windowbox thingies that can live in the greenhouse until warmer; but they are cut-and-come-again type, rather than Butterhead etc.
