Last Updated on August 16, 2023 by Real Men Sow

Basil in winter is a popular plant to grow at home. Basil is a great addition to any kitchen and doesn’t require a large garden. It is also great to plant near tomatoes to repel pests. Basil’s tolerance to cold and winter will be tested. It can withstand temperatures up to 40°F. 

Although the herb will not completely die, it will suffer severe damage. It will begin to fall and its leaves will turn dark brown. Basil can be damaged as soon as temperatures drop. Make sure you have a way of protecting your plant.

Keeping Basil Indoors for the Winter

You can save time by moving your plants indoors so you have enough time to harvest your plants before the cold weather hits. These are some of the options you can try:

  1. Place the basil in a greenhouse or in a room of your home.
  2. Take your basil to the kitchen. This is a good option as you will be using the basil most often before it rests.

Keeping Indoor Basil in Winter Alive

To keep your basil plant alive in winter, you need to give it as much light as you can. Here are some tips:

  1. Switch to artificial light sources during the dark winter months. A good starting point is 12 hours of daylight. This simple rule applies: Two hours of fluorescent lighting is equivalent to one hour of natural sunshine.
  2. Drain excess water from the soil and keep it warm.
  3. Put your basil in front of a window during daylight. Basil requires at least eight hours of sunlight each day to thrive.

I personally started gardening around 6 years ago and initially, I started out by growing my favorite fruits and berries, such as strawberries, Raspberries & Gooseberries. Since then I’ve added a lot of vegetables and working closely with my neighbor, it’s been a lot of fun.
