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.
You can try it. After the mums start to turn brown, cut them back to within 1 inch of the soil. Water and put the pot in a protected area (example: garage, cold frame). Surround the plant with newspapers and place newspapers below the pot.Check your mums once a month or so to see if it's getting dried out and water if so.fter the mums start to turn brown, cut them back to within 1 inch of the soil.
