Shade Tolerance 1

By: uvmext

All green plants, which includes trees, need sunlight to produce energy for survival. Some trees can satisfy their basic needs with less light than others. Sugar and red maples are two examples of such trees. They are both considered shade-toleran...

Maple Color Grades

By: uvmext

There are four grades of pure maple syrup; Golden Color/Delicate Taste, Amber Color/Rich Taste, Dark Color/Robust Taste and Very Dark Color/Strong Taste. Each grade has a range in color as defined by its light transmittance. Knowing the color of p...
