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.
Check the mums' soil moisture daily, and water the mums when the top 1 inch of soil begins to dry. Water the soil surface using a watering can until moisture begins to drain from the bottom of the pot. Empty the water collected in the pot's drip tray after each irrigation.
