Gardeners are unlikely to get much more production out of their tomato vines, said horticulturist Mary Anna Anderson of the University of Nebraska-Lincoln Extension in Sarpy and Douglas Counties.
Anderson said tomatoes with some color to them may slowly ripen if temperatures warm up. But those that are green are unlikely to advance beyond that stage, she said.
It's OK to leave the vines in place to baby along those that might still ripen, she said. However, disease is probably catching up with your vines. If the vines are diseased, discard them in the curbside yard waste rather than your backyard compost pile, she said.
That's because most backyard compost piles don't get hot enough to kill diseases, she said. Omaha's composting system will get hot enough.
However, do not rip out vegetables like cabbage, broccoli, cauliflower, brussel sprouts. These will sweeten with cooler weather and actually taste better after temperatures turn colder.
