Why does your Amygdalus persica have sudden leaf drop? Diagnose the cause and fix it with our step-by-step guide.
A lack of sufficient soil moisture causes the peach tree to enter a survival mode, shedding leaves to reduce transpiration and conserve water. This is often sudden following an extended period without rain or irrigation.
Excessive water or poor drainage causes this oomycete to attack the root system of the peach tree. The resulting damage prevents water uptake, leading to rapid leaf wilting and sudden defoliation.
Pathogenic bacteria clog the xylem vessels within the peach tree's leaves and branches, disrupting the flow of water. This often manifests as sudden browning and dropping of foliage, especially during hot weather.
A sudden late-spring frost can damage the new growth of a peach tree, causing the plant to drop its leaves as it recovers from cellular damage. This is common when temperatures drop sharply after a period of warm weather.
