Several Other Tips for Gardening in the winter Season in your Greenhouse

  1. Elevate your Plants – Remember from your science classes that cold air tends to sink to the bottom. Since this is the case, you must raise your greenhouse plants off the ground. Doing this will tend to keep them warmer during those cold winter months so as to prevent any damage.
  2. Try using some benches that are made of either metal or wood you put your plants on in order to keep them warm.
  3. Cover your Plants at Night – There are some plants that are quite sensitive to cold temperatures so what you will want to do is to cover them with sheet foam at night. This will help to keep the warmth in, and then in the morning when it starts to get warm inside your greenhouse you may remove the foam coverings.
