Plumerias are small to medium sized tropical trees with large leaves and clusters of fragrant flowers in a variety of colors. These delicate flowers are used to make leis. Leaf damage plumerias affects the ability of the tree to produce a healthy growth and may limit its annual flower production.
Environmental leaf damage is difficult to control, a late spring freeze, summer storms and heavy rains have all the potential to severely damage leaves of a plumeria tree. Frost damages the structure of the leaves, which leads to brown, dead parts that can hold pests and diseases. If the weather injury occurs, pinch severely wounded leaves and branches observed for signs of death, if they need to be trimmed.
Plumeria rust is a fungal disease that causes yellow-orange spots that appear on the undersides of the leaves. If the disease progresses, growing more and more spots on the leaves, rusty to the sheet, as if it has become looks. Heavily infested trees lose almost all their leaves, if the disease is left untreated. Plumeria rust with fungicide applications, the removal of infected leaves and twigs, and cultural support that prevents the disease controlled by the return, including weeding the area around the tree.
Spider mites are tiny pests that may go unnoticed to the casual observer, they look like red, green, brown or black spiders depend on the type of mite and what growth phase are fed in. These pests on the sap of plumeria leaves, biting holes in the leaves and sucking nutrients, the leaves need to survive. Over time, damaged by spider mites can turn yellow, droop and drop from the tree. Spider mites with regular applications of insecticidal soap.
Root rot is a disease caused by a variety of fungal pathogens that thrive in very damp soil and warm, humid conditions. As root rot concerns a plumeria, it limits the ability of the tree, take in water and nutrients by killing the roots. The leaves of yellow plumeria beginning at the tips, and will eventually fall from the tree. Death of limbs also occurs as a result of root rot. Root rot can not be controlled with fungicides, but maintaining well-drained soil and a careful pruning slows the spread of the disease.
