Preparing for the Sudden Onslaught of Winter

I feel like I spend a lot of time on this blog talking about the weather, but it really isn’t just idle conversation! The weather is extremely important to our success as gardeners. After one light freeze and lots of unseasonably warm weather, we are looking at more than a week of unseasonably cold temperatures. Overnight lows look like they will be hovering in the upper teens to low 20s for the better part of the next two weeks. (At least that low of 9 degrees is gone, for now!) Many of the cool season vegetables will tolerate temperatures down to 24 or 25 without significant damage, but two weeks of lows down around 20 is probably a bit much for them to tolerate, especially when they haven’t been hardened off with cold-but-not-too-cold temperatures.

So…it was time to harvest some things and cover others this afternoon! Because I can’t resist experimenting, I left one or two plants of almost everything in the garden, just to see what would happen.

We already had the cold frame out, but still open. We closed it up and tucked some straw along the back edge to keep the cold air out.

We also put hoops and row cover over the main section of spinach and radicchio. Normally I’d leave those out, but I think this will be a bit cold all of a sudden.

I left some of the other spinach around the garden uncovered, including the Indian variety. (I don’t have great hopes for its cold hardiness!)

I harvested a few of the radicchio plants to see what stage they were at. I also harvested the watermelon radishes, fennel, half the bunching onions, and most of the dandelion greens. I was just going to leave the lemongrass, but then I just couldn’t let it go to waste, so it went to our Foods & Nutrition department.

I’ll post more pictures and show what I did with some of the different vegetables later in the week!

  1. Sounds great, Rebecca–I would have helped if I had known–how did the guy do with the cannas?

  2. It’s about time to do the same thing! I was too busy lately and the weather dramatically changed during that time. Is the row cover enough to protect the spinach ?

    • It really depends how cold it gets and what the spinach has been accustomed to. It should survive into the low twenties without much protection, but if it gets too cold too fast then it could be dead.

  3. Thanks for the article! My harvest was ruined by the whether this autumn. I still have incredible tomatoes, but they freezed after the first frost. Keep going with the good advices! Regards!
