Here in Southern California we had a couple of warm weeks at the end of January. It's hard to have such nice weather and an empty garden and although we usually have frost well into March (and often April!), I decided to experiment and set out some cool weather seedlings to see how things went.
I did the garden prep and setup a fence inside the garden area so that the chickens could still come in and tend the unplanted side of the garden.
The first weekend in February, I put out 4-5 broccoli seedlings and 2 rows of sweet pea seed. The next weekend we had a pretty hard frost. Two of the broccoli did NOT look well. This week we had a hard freeze (I'm down to one thriving broccoli seedling now) and are expecting snow again this weekend!
