Following on from advice on this forum last year I opted for onion sets this year. I found Snowall and put them outside under plastic about 4 weeks ago. I have had to remove the plastic cover this weekend as the sets are all between 6 and 10 cm high, looking good, just a few lost to the birds from what I can tell. I just don't understand why my onion seeds never take.
I always start my seeds off on a warm windowsill avge 18degrees day and night, then put them outside under plastic and when required, bring them into the porch overnight.
Please can someone outline what to do, how to do it and when, can I still try onion seeds this year. I am determined to set my own onions
