The best time to prune a lemon tree is right after all the fruit has been harvested, which can vary depending on your USDA zone. However, it typically happens in later winter or early spring.
The blight spreads through an infected tree, invading and colonizing the plant's roots, leaves, and trunk. As of 2020, neither the causal agent nor the spreading mechanism of the disease is known. [2] Research by the Citrus Research and Development Foundation posits the blight is caused by an endogenous plant pararetrovirus (EPRV). [3]
The pittosporum flower weevil (Aneuma rubricale) is a parasite that feeds on the underside of the lemonwood leaves. This parasite does not kill the lemonwood it just damages the leaves through its feeding. The holes the weevils eat in the leaves are visible because the leaf reacts causing a dark brownie purple ring to form around the hole.
Citrus canker bacteria can enter through a plant's stomata or through wounds on leaves or other green parts. In most cases, younger leaves are considered to be the most susceptible. Also, damage caused by citrus leaf miner larvae (Phyllocnistis citrella) can be sites for infection to occur. Within a controlled laboratory setting, symptoms can ...

Deciduous trees experience much less branch and trunk breakage from glaze ice storms when leafless, and plants can reduce water loss due to the reduction in availability of liquid water during cold winter days. [16] Losing leaves in winter may reduce damage from insects; repairing leaves and keeping them functional may be more costly than just ...
Annual autumn leaf drop in temperate zones is caused by the abscission of the mature leaves from the growth season in response to the approach of cold winter weather. Abscission (from Latin ab- 'away' and scindere 'to cut') is the shedding of various parts of an organism, such as a plant dropping a leaf, fruit, flower, or seed.
The fungus survives the winter on the surface of the host plant, such as on bark or buds. [2] In late winter or early spring, rainwater washes spores into the buds as they burst. Once this happens, no treatment is effective. In the spring, about two weeks after blossom, new leaves emerging from the infected buds are infected by the conidia.
