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.
Plant the mums. Set the mums into the holes. Place the composted soil over the top of the root system and lightly tamp it down. If you're planting mums in pots, set the mums on top of the layer of soil, then cover them with more soil on top. Lightly tamp down the soil to set the plant in place.
