Right, well I threatened this earlier, and here it is - not so much Gardener's World, but 'One gardener's world'. An opportunity for all to learn from the mistakes of another.!
Here we see what happens if you plant tomato seeds in a heated propagator in February, because you have no patience whatsoever - a nice display of leggy tomato plants. (Note the tomato-world's very own Peter Crouch on the right).
And here is the only way to save them it seems - plant out in a cold greenhouse in March and abandon (for much healthier looking plants).
And here is a leggy chilli plant, already in flower
And these straggly cucumbers show something else that can be achieved by planting much too early in a heated propagator and then having things go a bit stir crazy on a windowsill for weeks.
A fuzzy cucumber!
This photograph proves that you should always listen to your friends on this forum, because when I said I didn't know what to put in my greenhouse, someone suggested some early salad in a growbag, and hey presto - here it comes!
And here is proof that Country Value sweetcorn seed will grow in a greenhouse, as will any Thomson and Morgan Speedy bean seeds that are two years out of date. AND - miraculously, a sunflower seed that our foster son planted in a plastic cup at Beavers back in... I can't remember exactly. I watered if for weeks, for a laugh, and was on the point of throwing away when a (leggy) seedling popped up overnight.
Proof that if you plant your cosmos too early, it might flower before it's even safe to plant out.
And evidence that an agapanthus can spend a long time going nowhere.
