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. Leaf senescence has the important function of ...
Plant litter (also leaf litter, tree litter, soil litter, litterfall or duff) is dead plant material (such as leaves, bark, needles, twigs, and cladodes) that have fallen to the ground. This detritus or dead organic material and its constituent nutrients are added to the top layer of soil, commonly known as the litter layer or O horizon ("O ...

You love what houseplants do for your interior , but when it comes to caring for them you’re more of a grim...
A plant will abscise a part either to discard a member that is no longer necessary, such as a leaf during autumn, or a flower following fertilisation, or for the purposes of reproduction. Most deciduous plants drop their leaves by abscission before winter, whereas evergreen plants continuously abscise their leaves. Another form of abscission is ...
The largest specimen known is at Spring Grove Cemetery in Cincinnati, Ohio, 22 m tall and 2.2 m trunk diameter; the tallest known is a slender tree 27 m tall but only 0.55 m trunk diameter, at Plott Cove Research Natural Area, Georgia (Spongberg & Ma 1997; Eastern Native Trees Society). Plants from Alabama have the leaves more densely hairy ...
But since tree damage can be extensive, filing a claim does make sense in many cases. If you have proof that your neighbor knew that their tree was a risk, that’s information you should provide ...
