Deciduous shrub, 1 to 1.5 meters high, palmately lobed leaves with five lobes. Strong shrub, sensitive to aphids and white disease. Birds also sometimes want to peck a berry.

Currants: redcurrant (Ribes rubrum) blackcurrant (Ribes nigrum) and gooseberry (Ribes uva crispa) originate from the western part of Europe. Deciduous shrubs, 1 to 1.5 meters high, palmately lobed leaves with five lobes. The plant has inconspicuous, yellow-green flowers. The berries (red, white or black) have a diameter of between 8 and 12 mm and hang in clusters of 3 to 10 berries. The length of the truss is 4 to 8 cm. An adult bush can yield 3 to 4 kilos of berries; harvest July, August and early September. Gooseberries are usually green and covered with fine hairs.
Leaf, blossom and ovary are eaten by caterpillars (the berry span caterpillar) of the magpie moth (Abraxas grossulariata) .
Deformed leaf and berry: aphid.
Young leaves are eaten away: caterpillars of the common gooseberry sawfly (Nematus ribesii) .
Wilting branches; tunnels in perennial wood: currant clearwing (Synanthedon tipuliformis) .
Buds are thick and do not open or are misshapen: big bud mite (Cecidophyopsis ribis).
Red blisters on the leaf: Red Currant Aphid (Cryptomyzus ribis).
Small yellow-orange (rust) spots on the leaf: rust.
Holes in often a single berry with spinning around it; berry matures early: Gooseberry Knot-horn (Zophodia grossulariella).
Soft spots develop in the red berries, the berries become dull and can then rot: Asian fruit fly (Drosophila suzukii).
Fungi & diseases
Leaf and berry are covered with white mold: powdery mildew (Podosphaera mors-uvae).
Brown spots followed by grey mold fluff: Gray mold (Botrytis ssp.).
Orange-red bumps on the branches; branches die off, sometimes followed by the entire shrub: coral spot (Nectria cinnabarina).
Small, irregular black-brown spots on the leaf, after which discolouration to yellow or brown; affected leaves already fall in July after harvest: Currant and gooseberry leaf spot (Drepanopeziza ribis).
Berries are snatched: birds.
Leaf margin discolours, curls and withers. Early leaf fall: potassium deficiency.
In early spring, starting berries have dried up and fallen off: frost damage.
Damaged and subsequently dried out ripe berries: hail and heavy rain can cause this, especially after a period of drought followed by rain. The berries swell, making the skin thin and fragile.
