The leaves of the plant can be picked off with a pair of tweezers if they become chlorotic or brown. Leaf drop is caused by a fungus called Phytophthora infestans, which causes the leaves to fall off. The fungus is found on many species of trees and shrubs, but it is most commonly found in boxwoods and other conifers, such as Douglas-fir and hemlock.
When the fungus infects a tree or shrub, it releases spores into the soil. As the spores germinate, they attach themselves to a host plant, causing it to become infected. Once the infection is established, the infected plant can no longer produce new leaves, so it must be cut down and replaced with new growth.
This process can take weeks or months, depending on the size and number of infected plants. It is important to note that leaf drop does not necessarily mean that a plant is dying. In fact, many infected trees can continue to produce leaves for months or even years after the initial infection has been detected.
