Scars in Common dogwood are physical indicators of damage, abnormal plant growth, or disease response. These may not be a disease but can result from various biotic and abiotic factors, affecting the plant's health and appearance.

Yellow edges is a disease that targets the leaves of Common dogwood, causing the edges of the leaves to turn yellow, droop, and eventually dry out. This disease results in stunted growth and reduced vitality of the plant, often leading to plant death if left untreated.

Leaf tip withering

Leaf tip withering is a condition affecting Common dogwood, characterized by the gradual browning and death of leaf tips, potentially diminishing photosynthesis and overall vigor of the plant.

Notch disease in Common dogwood is characterized by marked indentations on leaf edges. It's particularly detrimental during the blooming stage, leading to weakened growth and aesthetic decline of the plant.

Dark blotch is a fungal disease that affects Common dogwood, causing purple to black leaf spots. The disease retards the growth of the plant, often leading to eventual death if not treated early.

Spots is a common fungal disease affecting Common dogwood primarily. It degrades plant health by forming black or brown spots on leaves, leading to early leaf fall and reduced vigor.

Whole leaf withering

Whole leaf withering is a disease impacting Common dogwood, leading to rapid deterioration and eventual death of foliage. Crucially affecting the plant's health and aesthetics, this condition can severely limit its growth and reproductive capabilities.

Flower rot is a fungal disease causing early defoliation and discoloration in Common dogwood's blossoms, resulting in a significant drop in plant aesthetics and vitality. The disease peaks during wet, warm periods and is moderately infectious and lethal.

Wounds on Common dogwood are physical damages caused by external factors, leading to compromised plant health. It exposes Common dogwood to pests and diseases, inhibiting growth and potentially causing premature death.

Mealybug is a pest that targets Common dogwood, causing leaf yellowing, stunted growth, and reduced photosynthesis. It primarily affects plant vigor, leading to significant ornamental and physiological damage.

Whole plant withering

Whole plant withering is a serious condition affecting Common dogwood, leading to rapid decline and death. It is marked by wilting across the entire plant, often linked to root system failure or pervasive infection.

Leaf white mold

Leaf white mold is a fungal disease that affects Common dogwood, causing foliar damage and potentially impacting the plant's overall health. The disease is characterized by the presence of white, cottony growth on leaves, leading to reduced vigor.

Black mold is a fungal infection affecting Common dogwood, causing discolored patches on leaves and stems, potentially leading to reduced vitality and growth.

Leaf Drooping in Common dogwood is a condition causing the leaves to sag and weaken, often affecting the plant's overall vitality and aesthetics. It can result from various factors, impacting the plant's health if left unchecked.

Stem blackening on Common dogwood leads to dark discoloration and potential weakening of stems. The disease affects plant vigor and aesthetic value, often escalating during favorable conditions.

Interveinal yellowing

Interveinal yellowing in Common dogwood is a condition leading to the loss of green pigment between leaf veins, causing aesthetic and physiological stress to the plant, and may be indicative of underlying health issues.

Scale insects cause significant stress on Common dogwood, leading to discolored foliage, reduced vigor, and possible death if untreated. The disease primarily affects leaves but can spread to stems.

Dark spots is a fungal disease that primarily affects the leaves of Common dogwood, resulting in dark, round lesions. If untreated, it severely weakens the plant, compromising its ability to photosynthesize efficiently and potentially leading to its death.

Leaf blotch is a fungal disease causing irregular brownish spots on Common dogwood leaves leading to premature defoliation and reduced vigor. Control is essential for maintaining plant health.

Branch withering

Branch withering is a disease that affects Common dogwood, leading to premature foliage discoloration, branch dieback, and potentially the death of the plant if left untreated.

Non-base branch withering

Non-base branch withering in Common dogwood results in progressive death of upper limbs, impacting overall health, aesthetics, and vigor of the plant.

Flower wilting is a plant disease that severely affects Common dogwood, causing a decline in blooms, weakened growth, and eventual death if left untreated. This disease is typically induced by improper care, pathogens, or harsh environmental conditions.
