MaximumYield explains Defoliation
A widespread loss of a plant’s leaves through defoliation is unnatural and is usually caused by a range of external factors. Plants generally go through photosynthesis using their leaves, and due to the lack of leaves, defoliated plants are unable to undergo photosynthesis. This lack of natural process that creates nutrition can impede the growth of the plant and cause it to be malformed.
To know whether your plant is defoliated, simple signs on leaves include chewing from insects and animals, signs of disease like spots, mildews and molds. Also, check for the possibility of chemical treatments around the area where you plant.
