Focusing primarily on both the understanding of our natural and man-made environments, environmental science degrees draw from diverse fields of studies and require a strong background in the more traditional sciences: biology, physics, chemistry, geography, ecology, and even biotechnology.
When and how to pinch back mums. If you decide to prune your mums, you can start pinching stems in spring when the plants have reached a height of about 6 inches. To pinch them back, simply grab a stem between your thumb and index finger about 2 to 3 inches above the base of the plant and just above a leaf and pinch it off.
Dig holes for the mums. Pull the mums from the plastic container they came in and set them where you plan to plant them. Dig holes that are 1 inch (2.5 cm) deeper than the length of the roots, about 8 to 10 inches (20.3 to 25.4 cm). This will vary depending on the size of your mum plant.
