From what I have read around the internet, one of the main causes for this is improper plant nutrition of some kind. It is happening to me right now because I used too much MiracleGro, so the plants were getting too much nitrogen, which caused some yellowing of the leaves and the falling leaves and flowers. I ran across this site, which might be helpful to you, they talk about this very thing, and someone was successful in saving their plant by using an epsom salt and water mixture.
Yes some plants have leaves which fall of like mango leaves . But there are some plants of which leaves do not fall , like oak leaves.
These plants are called evergreen plants
These plants are called deciduous plnts shedding all leaves at a time. New leaves and flowers come later in these plants.
Bougainvillea plant fall their leaves during a hot day.
They are called "evergreen" plants but the leaves do fall down and get replaced, just not all at once.
Plants actually shed their leaves so they CAN survive! Plants wich have no leaves get more nutrients to the roots, making them live longer. This is why you should prune your plants in the fall.
they fall off
Deciduous plants lose their leaves in fall. Some trees are Oak, Maple, Poplar, Ash, Walnust, Butternut, Dogwood, Redbud, and many more.
we get oxygen from plants that live during the winter such as pine tress
These are deciduous plants and that is what the word means; " leave's shed "
Because the leaves get cold and die.
a change in weather
Plants need to lose leaves in the fall because the leaves are very dry. In the winter, plants already have all their leaves lost in the fall, but they can't grow back because it is too cold. In the spring, it gets warmer so leaves can grow back. In the summer, a few leaves die because they are too hot and too dry.
Plants which do not lose their leaves in fall/ autumn are called Evergreen, an example is the confier
Plants that loose their leaves in fall (or autumn), prior to the winter are called deciduous.Examples are: Ash, Oak, Prunus,
Trees. The leaves *fall from the trees in autumn. That's why some people call it *fall instead of autumn.your friend,----- Bucky Badger of WISCONSIN
The pigments change color in the chlorophyll in the cells in their leaves.
Stored energy. plants are always doing photosynthesis. it gets stored for the winter.
Yes, each fall sugar maples (and other deciduous trees) remove the chlorophyll and other important compounds and nutrients from their leaves (which causes the other colors to become visible) and then drop the leaves.
The light and temperature changes that are associated with fall cause the foliage leaves to change colors. The cold effects the glucose found in the leaves causing this transformation.
