Those are the instructions for storage on the label. What does that mean and why? We provide the storage information on our labels for the best handling and management of our chemical products. If chemical products are too cold, they won’t flow into the tree. Some products are already syrupy by nature and the cold temperature makes them more viscous or thicker. Spring and fall are particularly difficult as the temperature ranges significantly. If the product is at the correct temperature, you will have no problem injecting it into the tree.
