Quick Scoop

If you want to keep tomato plants through winter, the safest options are to bring healthy plants indoors, overwinter cuttings, or compost/remove frost- damaged plants if you do not have space or light for indoor care.

What to do

  • Move potted tomatoes indoors before the first frost, prune them back, and place them in the brightest possible spot; a grow light helps a lot because winter windows usually do not provide enough light.
  • Take cuttings from healthy plants and root them indoors for a smaller, easier-to-manage plant to replant in spring.
  • Store dormant bare-root plants in a cool place such as a garage, cellar, or even a fridge in some cases, if you want to save larger plants for next season.
  • If the plants are done for the year , pull them out after frost and compost them rather than leaving dead or diseased vines in the garden.

Winter care tips

Keep indoor tomatoes on the dry side, water sparingly, and watch for weak growth caused by low light. Before spring planting, gradually reintroduce them to outdoor conditions so they do not get shocked by cold or sun.
