Sometimes, the veins of rose bush leaves will turn yellow. Often, the leaves will then become brown and dry and drop off the plant. Oxygen deficiency causes this in rose bushes, and is often present in plants that have poor drainage and are constantly sitting in soggy soil.
Common Causes of Leaf Discoloration. Overwatering is most damaging to the roots and stems of a peace lily and can cause its foliage to collapse and become necrotic. If the plant does not receive enough water, then its foliage wilts to the point of falling to soil level, and the leaves turn yellow and brown.Magnesium deficiency also can cause a peace lily's leaves to yellow and it can stunt the plant's growth.Foliar sprays are recommended when they are warranted by the severity of the deficiency.eace lily, also called white anthurium, snowflower and spathe flower, removes toxins, including benzene, carbon monoxide and formaldehyde, from interior air. Although the plant is relatively maintenance-free, improper lighting and watering can cause its leaves to burn, yellow, brown, wilt or even die.
