Safety & Hazards

When the prickles on the stem and the fruits become too hard, they can cause intestinal inflammation in grazing animals[1]. The roots are toxic in large doses[2].

Cultivation Details

HabitAnnual/Perennial
Growth—

A plant of the tropics, but also naturalized in the subtropics, where it is found at elevations up to 1,300 metres. It grows best in areas where annual daytime temperatures are within the range 22 - 28°c, but can tolerate 10 - 32°c[1]. It is intolerant of frost[3]. It prefers a mean annual rainfall in the range 1,000 - 2,000mm, but tolerates 900 - 3,000mm[1]. Prefers a sunny position, but can succeed in quite dense shade[1]. Plants are shade intolerant[3]. Succeeds in most soils, including those that are shallow or poor in nutrients[1]. The plant is well adapted to humid areas with high winds[1]. Prefers a pH in the range 6 - 7, tolerating 5 - 7.5[1]. The plant has become naturalized throughout the Tropics and much of the subtropics[4]. It has become a pest in forest plantations, cropland, orchards and pasture[3]. It is particularly likely to become a noxious weed when growing in dryland field crops, in rainfed wetland rice and in plantation crops[1]. Plants can flower all year round[1]. Plants are a fire hazard when dry[5]. Although they can be perennial, the plants can also complete their life-cycle within 90 days[1]. This species has a symbiotic relationship with certain soil bacteria, these bacteria form nodules on the roots and fix atmospheric nitrogen. Some of this nitrogen is utilized by the growing plant but some can also be used by other plants growing nearby[6].

Propagation

Seed - it has a hard seedcoat and may benefit from scarification before sowing to speed up germination. This can usually be done by pouring a small amount of nearly boiling water on the seeds (being careful not to cook them!) and then soaking them for 12 - 24 hours in warm water. By this time they should have imbibed moisture and swollen - if they have not, then carefully make a nick in the seedcoat (being careful not to damage the embryo) and soak for a further 12 hours before sowing.
