When is lettuce too lanky?

I sowed some more seeds a few weeks back and so far (touch wood) they seem to be doing ok...apart from my Tumbling Tom Tomatoes (which haven't done anything) and my lettuce which went from just pushing through the soil to about 2 inches tall and barely able to hold itself up. Does this mean it's too weedy to do anything? Will have to re-pot it on the weekend to see.

What seems to be going well so far are spinach, sweet basil, alisa craig and sweet millions tomatoes, borage, parsley and garlic chives. As well as the garlic I planted early Feb.

And sow it begns...

I did manage to get some seed sown yesterday. I planted Garlic Marco in pots outside and on my kitchen units I now have Ailsa Craig tomatoes, Jalepeno Peppers, Sweet Peppers, Basil, Parsley, Garlic Chives, Borage, Thyme, Ornamental Pepper - Firestorm & Coriander in mini propogators.

I also bought a mini Bay Bush (tree?) that is currently sitting on my window sill. And on Saturday I re-potted 5 Rosemary plugs i got on eBay and Majoram.

I am really looking forward to working in the garden, and am a bit gutted we're going to Scotland next weekend and won't be able to carry on! Will post more pics soon.
