Cultivation details
S. torvum is an erect or spreading prickly shrub, 1 to 3 m tall. A plant of the moist tropics, where it is found at elevations up to 1,600 metres. Succeeds in full sun and in light shade [418 ]. Grows well in a range of fertile, moist but well-drained soils [418 ]. Prefers a pH in the range 5 - 6 (acidic), tolerating 4.3 - 6.8 [418 ]. Plants can tolerate some drought [305 ]. It grows best in areas where annual daytime temperatures are within the range 17 - 29°c, but can tolerate 12 - 35°c [418 ]. It prefers a mean annual rainfall in the range 1,000 - 2,000mm, but tolerates 700 - 4,200mm [418 ]. Heavy rainfall discourages fruit set [418 ]. The plant is spread by birds that eat the fruits and spread the seeds. It is considered to be a major weed in pastures, along roadsides and in wasteland in the tropics. It also occurs in plantations, but is not found in significant quantities in cultivated land [305 ]. Often found in disturbed areas, it can form dense impenetrable stands. Solanum torvum is considered to be a serious threat to the productivity and sustainability of pasture [413 ]. Besides its economic impacts, it competes with native species [413 ]. The plant commences flowering when 3 - 4 months old and is said to have an economic life of 3 - 5 years[299 , 418 ]. The plant can flower and produce fruit all year round [266 ]. It can regrow after a fire [305 ]. There are named forms in Africa and in Thailand [299 , 301 ]. At least one form is free of prickles [777].

Weed Potential
Right plant wrong place. We are currently updating this section.
Please note that a plant may be invasive in one area but may not in your area so it’s worth checking.
Once established, S. torvum can, by sprouting from the roots, form dense thickets capable of overrunning farmlands and pastures, and of displacing native vegetation. Turkey berry can rapidly overtop most herbs, grasses and other shrubs but cannot survive under a closed forest canopy. The vicious spines on the stem and small prickles on the leaves, inhibit the free movement of people, livestock and wildlife [1-8].
