Dark spots on Red flowering currant are caused by a fungal pathogen, leading to discolored lesions on leaves and stems. The disease can hinder photosynthesis and weaken the plant if severe.

Aphids are a common pest affecting Red flowering currant, causing distorted growth, discoloration, and reduced vigor. These pests extract sap, weakening the plant and potentially spreading viruses.

Flower withering

Flower withering is a botanical disease that heavily affects Red flowering currant, causing its vibrant blossoms to deteriorate prematurely. This disease occurs due to various factors, altering the plant's vital functions and, often, resulting in stunted growth or even death.

Leaf tip withering

Leaf tip withering in Red flowering currant is a condition causing leaf desiccation, discoloration, and potential defoliation. It impacts overall plant health and can lead to reduced vigor and aesthetics.

Whole leaf withering

Whole leaf withering is a disease that affects Red flowering currant, causing premature leaf decay and significant disruption in photosynthesis. It impacts the health and visual appearance, possibly leading to reduced blooms.

Leaf drooping in Red flowering currant typically indicates water stress or nutrient deficiency, significantly affecting the plant's aesthetic and health by causing wilting and potential leaf loss. Proper identification and swift address of the underlying causes are crucial for recovery.

Yellow edges is a plant disease that affects the foliage of Red flowering currant, resulting in discoloration and potential decline in overall plant vigor.

The 'Notch' disease in Red flowering currant primarily manifests as distinctive notching and discoloration on leaves. A fungal infection, it affects the plant's aesthetics and vitality but is rarely lethal.

Leaf blotch is a fungal disease affecting Red flowering currant, causing irregular dark spots on leaves and potentially reduced flowering. Management includes cultural practices and fungicides for severe cases.

Scale insects are pests that attach themselves to the stems and leaves of Red flowering currant, sapping the plant of vital nutrients. Infested plants display stunted growth, leaf yellowing, and premature leaf drop, potentially leading to plant death if untreated.

Gall disease in Red flowering currant is caused by various pathogens resulting in abnormal plant growths. It affects the overall health and aesthetics of the plant, leading to reduced vigor and potentially death if unchecked.

Whitefly is a pest rather than a disease that primarily affects Red flowering currant by sucking sap, leading to weakened growth, yellowing leaves, and potential sooty mold from excreted honeydew.

Lichen, though often mistaken for a plant disease, is a symbiotic relationship between fungi and algae that generally does not harm Red flowering currant. It appears typically on stressed plants or slow-growth areas, manifesting as patchy, leafy clusters.

Non-base branch withering

Non-base branch withering primarily affects Red flowering currant, causing premature death and decline in plant vigor. This disease dramatically reduces aesthetic and ecological value of affected plants by impeding flowering and growth.

Flower rot is a fungal disease primarily causing wilting and browning of Red flowering currant's flowers, potentially leading to plant death. Prompt detection and control measures are pivotal to manage infection spread and plant survival.
