It is cold! I just came inside from my garden to gauge whether or not I should cover anything with burlap. My unscientific diagnosis says no. It felt more like a refrigerator than a freezer and the expected low is in the 40s tonight.
That being said, be careful to watch the upcoming night lows. If you’re on the fence about covering a plant, do it. Just be sure to remove the cover in the morning.
The first freeze will be here soon. Don’t depend solely on the weather report or backyard thermometer to tell you this. Your garden may have micro climates that can cause an area to be cooler or warmer than those temps (for instance, next to a cinder block wall).
When the freezing temps arrive, your garden will require a little more care so you don’t lose your plants. If it’s a container garden, this could mean moving them to a sunnier part of the yard or inside during a night freeze. If it’s a permanent garden, this can mean covering your bed with mulch to insulate and protect the roots, and covering the plant with a breathable material to fend off frost.
If you are still growing tomatoes (like me) be sure to pick all of them before the first freeze, including the green ones. They will continue to ripen indoors, just make sure they get plenty of sunlight. I leave mine in a window sill after the freezing temperatures are over with. It’ll take a while, but when the moment is right, you’ll come home to red tomatoes. Last year, I was eating fresh tomatoes in January 🙂
