Some plants just don't like the cold and you'll never get them to go through the winter, even if you can keep the temps above freezing in your greenhouse or hoop house. Basil is a good example. It spots and pouts if the temp gets down near 40 degrees. Not to worry! There are plenty of plants that love cold weather.
Good cold/cool weather plants are:
- pak choi
Plants that must have very warm soil to be happy are:
- sweet potatoes
- red long beans
By planting things during the right season, you can double or triple the production of your garden. Plant carrots and lettuce under cover now, then harvest it in early May, when you can pop some melons and basil in that same bed. Then when you harvest the melons and basil, you can plant a winter garden and have radishes, carrots and arugula all winter long.
