Problem: How to identify cold spots in your fridge
Gather a notebook and writing utensil.
The main problem with cold spots is that they're invisible, which makes them easy to forget. Having a notebook and writing utensil handy in the kitchen will give you the opportunity to make a log of freezing.

Answer: You might find it even easier to remember this if you use a magnetic pen/notepad. This way, when you look at the fridge, you'll be reminded about cold spots.

Pick a sunny spot.
Chestnut trees grow best when grown in direct sunlight. For best results, choose a location that receives six or more hours of direct sunlight each days during the growing season.
