Actinidia arguta, commonly known as tara vine, is a climber.
Actinidia arguta was described by Friedrich Anton Wilhelm Miquel in 1867. The name is considered as validly published.
The climbers are comparatively fast-growing and reach heights of 6 to 7 metres. The plants reach a width of 1.5 to 2 metres.
Actinidia arguta is deciduous. The green, simple leaves are alternate. They are ovate and petiolate with denticulate margins and pinnate venation. The surface of the leaves is pilose. They turn an attractive yellow in autumn.
Flowers and Fruits
Actinidia arguta produces cluster of white cup-shaped flowers in June. The plants flower on older shoots. They are dioecious.
The climbers produce green berries in autumn. The fruits have a sweetish taste.
The plants form shallow roots.
Actinidia arguta is native to East Asia.
The climbers prefer a sunny situation on moist soil. The substrate should be sandy-loamy, sandy clay, loamy clay or peaty soil with a pH between 6,5 and 7,5. They tolerate temperatures down to -29Â°C (USDA zone 5).
Tolerance of special soil conditions
- high: city climate
The ornamental value of Actinidia arguta lies especially in its fragrance.
Maintenance and Propagation
The plants usually require only a moderate amount of maintenance.
Pests and Diseases
Cankers indicate an infection with fireblight. Generously remove affected parts and destroy them.
Leaf blotches are a sign of a fungal or bacterial infection. Bacterial spots are rather angular and yellow-rimmed while fungal spots usually are rather rounded with an area of fruiting bodies. Destroy affected parts, additionaly apply fungizide it is is a fungal infection.
Fine webs on the plants indicate an infestation with red spider mites. These sap-sucking insects mainly appear under glass and can be controlled either with insecticide or biologically with parasitic mites.
Distorted and discoloured leaves indicate an infestation with eelworms. Infected plants usually die and should be destroyed.
Sudden wilting and pale green discolouration indicate a fungal infection (phytophthora). Remove infected plants. Avoid by improving drainage and over-fertilization.
White spots on flowers and leaves in combination with buds that do not open indicate an infestation with thrips. These insects can be controlled by improving ventilation and by watering regularly as well as by using an insecticide or biolocial pest control (predatory mites).
