Last night, with the weather forecast predicting lows in the 40s, a friend suggested I cover my tomato and pepper plants. I put dry cleaner plastic over the tomatos and glass jars over the peppers. This morning, with the weather forecast predicting showers and highs in the mid 50s, I decided I could just leave the plants covered. I figured the plastic would divert any rainwater to the base of the tomato and I could water the peppers tomorrow.
Now at work, however, I began to wonder if leaving the peppers under the glass jars would deprive them of oxygen? The plants are small, not more than 4 or 5 inches tall and the jars are inverted resting directly on the soil.
Should I have removed the jars, or at least raised them slightly off the ground? And are the tomatos ok?
