simply when they droop and get attracted by gravity.
When the first leaves of a plant start to change color in the fall, it is a sign that the chlorophyll in the leaves is breaking down. This process reveals other pigments in the leaves, such as carotenoids and anthocyanins, which give the leaves their autumn colors. Eventually, the leaves will fall off the plant as part of its natural cycle to prepare for winter.
They are called "evergreen" plants but the leaves do fall down and get replaced, just not all at once.
In the fall when the plant stops making chlorophyll.
No cut them off
No, a weed plant would not die if its leaves fall off. The plant may undergo some stress, but it can recover and produce new leaves as long as its roots are healthy and the growing conditions are favorable.
Jade plant leaves may fall off due to overwatering, underwatering, lack of sunlight, or pests. It is important to maintain proper care and conditions to prevent leaf loss.
They fall off and turn rainbow colors )
The leaves of a green plant would typically lose the most chloroplasts as summer turns to fall. This is because chloroplasts are primarily located in the mesophyll cells of leaves, which are responsible for photosynthesis. As the days get shorter and temperatures drop in the fall, leaves begin to senesce and chloroplasts degrade or are broken down.
An important fact about plant pigments is that it colors the plant green. It also makes leaves yellow and orange in the fall.
They usually go crisp and brown and die (some plant leaves can survive this). -------------------------------------------------------------------------------------------------- they will probably fall from the tree
Rubber plant leaves may fall due to overwatering, underwatering, lack of sunlight, or sudden changes in environment. Check the plant's watering schedule, light exposure, and surroundings to address the issue.
