With fall upon us and the leaves changing color and falling to the ground, the age-old question arises: Should I rake my leaves?
Plant senescence is the process of aging in plants. Plants have both stress-induced and age-related developmental aging. [1] Chlorophyll degradation during leaf senescence reveals the carotenoids, such as anthocyanin and xanthophylls, which are the cause of autumn leaf color in deciduous trees.
The solution: During the growing season, fertilize peace lilies about once a month with a diluted, liquid organic fertilizer. To give the plants an added boost, sprinkle a bit of organic compost ...
During the growing season, however, the plant replenishes the chlorophyll so that the supply remains high and the leaves stay green. In late summer, with daylight hours shortening and temperatures cooling, the veins that carry fluids into and out of the leaf are gradually closed off as a layer of special cork cells forms at the base of each leaf.
In the fields of horticulture and botany, the term deciduous (/ d ɪ ˈ s ɪ dʒ u. ə s /) [1] [2] means "falling off at maturity" [3] and "tending to fall off", [4] in reference to trees and shrubs that seasonally shed leaves, usually in the autumn; to the shedding of petals, after flowering; and to the shedding of ripe fruit.
