Just thought I would update you on this - well, now of course just to annoy me, the seeds I sowed have actually sprouted this time and the tiny onions are growing, despite our current hot dry period. I am watering them every couple of days.
I transplanted a whole heap of seedlings from mdoules, fiendishly difficult to plant as they were still quite small and now I don't know if they are thriving or not, they are still green in the middle but some of the tips seems quite shrivelled, is that normal?
In the meantime, it seems that the best way for me to grow leeks from seed is in a sheltered coldframe, I sowed some a few weeks ago and they are looking much better than the ones I started indoors and are now in a pot in the open. A very experimental period for me in the garden, as you can see!!! ;)
