Mould!

I just noticed that the five tubs of seed mixture that I have in the living room (pansy, lavender, and sweet pepper) have gone MOULDY and are covered in white fluffy stuff. Yuck. I've never seen this happen before! I've got no idea what's going on - I'm pretty sure I haven't been over-watering them, but I can't think of what else might have caused it.

For the moment, I've moved them all to the sunny windowsill rather than the rather darker corner behind the curtains. If it persists, I'll probably have to throw them out. The first casualties of summer 2009 and they didn't even get a chance to germinate. Bah.
