joanne brady asked 12 years ago

because my garden is brand new I wont be sowing any veg until the spring but I wanted to have lettuce variety over the winter. sowed couple of varieties of spinach and lettuce 2 weeks ago in flat boxes of seed compost and have them in a sunroom at around 19/20 degrees. seeds have germinated but seedlings dont seem to be growing much and very spindly and not upright (look like they are falling over!) but soil looks moist so cant be under watered. am I too impatient or how long should I expect seedlings to start thriving? do I have to thin them if Im growing them in the boxes for cut and come again? or can I just leave them and wait…?

A sunroom is generally not bright enough for lettuce which needs as much light as possible. The temperature is okay but the warmth pushes on the seedlings inthe absence of sufficient light and they grow spindly.

It would be better off in a cool greenhouse with more light and less heat. Leave them be and see how they do. You might be able to use them as cut and come again plants.
