I have yet to figure out how to grow brassicas in the Eastern Ontario climate. I suspect a lot of effort is involved and, until now, I have not been that dedicated (let's see how this year goes!).
My first effort was just a couple of years ago in the summer of 2012 when my attempt at growing brussels sprouts and cabbage was foiled by the hot, dry summer and thirsty/hungry deer that demolished many veggies that year (there were hoof prints inside the raised garden so I could easily identify the culprit).
So rather than starting them in April as I did last year, I have just started them as seeds indoors. But wow, they germinated quickly! After only a few days, they are well on their way and I worry I've started them too early again.
Any advice would be appreciated for the Eastern Ontario growing climate!!!!
