Over winter I grew a few salad greens in containers on my front deck, this was surprisingly successful. With all the rain no watering was needed and I could pick salad greens any time. Winter also means almost no pests! Well certainly no aphids, there were a few brave snails. These can be dealt with by hand no nasty chemicals needed.
I bought the plants as seedlings on sale at kings plant barn.( I suck at growing things from seed). While they were pretty slow growing at times I still got plenty of value. This is my corn salad, a mild small leaf green. I planted six of these. Occasionally I'd pull a whole plant but mostly just cut off bunch of leaves as needed.
And this is the mizuna, its just going to seed. I should have grown this in a bigger pot. This is often sold in the herb section, but it grew well over winter.
I also planted some perpetual spinach, which I hope will perpetual all over the place saving me from buying any more. As long as you pick the right types of plants you can have fresh salad all year round. Its easy as bro!
