This week the kids had the solemn task of removing their frozen tomato plants. Three days of frigid temperatures—by Florida and tomato standards—were simply too much for the sweet things.
We salvaged what we could and will hope for the best when it comes to ripening “post vine.” Not sure how they’ll fare, but our spirits remain high.
Not only will we plant a new crop this spring, we’re going to make ketchup with our harvest. Hip-hip-hooray! AND–we’re going to plant potatoes for French fries! Does it get any better? Only if you prefer mayonnaise on those fries! Besides, our broccoli is ready. Who can’t be happy about that? The kindergarteners promptly took it back to class and washed it for a nice, healthy snack. YUM.
Even had a visitor while we were out there. He was so busy scouring our broccoli blooms for nectar, he didn’t even notice us!
But why do plants die during a cold snap, anyway?
Actually, not all do. Our cabbage and broccoli thrive in the cooler weather much like our carrots. See? No problem here! Other than weeds, of course. 🙂
But tomatoes and peppers? Not so much. The reason? Like other living forms, plant cells contain water and water can freeze. According to scientists, during a frost, if water in plant cells freezes, it can damage cell walls. Why? Because solid ice takes up more space than the liquid from which it was frozen. The crystals then rupture the tough cell walls and when the ice melts, any liquid drains out, dehydrating the plant. Soil can also freeze, which threatens plants’ abilities to get nourishment.
The kids also learned that several factors can affect how damaging a cold spell will be, such as how long the temperature remains low, whether or not it’s a clear evening versus a nice warm “blanket” of cloud cover, are your plants located in low spots or high across your landscape—even the difference in heat retention between dark soil and light! Amazing, yes. But true?
I sure hope! Our school garden is LOADED with rich dark dirt and it sure would help protect our plants against the cold. For complete lesson, check the Kid Buzz section—and by all means, pay attention when the weatherman says we’re in for some chilly weather!
See ya next week!
