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.
Keep your garden mumsâ soil moist as winter approaches. As the blooms fade, deadhead them to avoid having any stray seedlings come up. Itâs best, however, to leave all the foliage in place until spring. Mulch the plants after several hard frosts with salt marsh hay or evergreen branches.
