Safety & Hazards

Many Agave species have strong, sharp spines on the leaves and leaf tips. In theory at least, the flowers, nectar, immature flowering stem and the centre of the rosette of all Agave species is edible and, with proper preparation, can provide a sweet, tasty foodstuff. Some species, however, contain relatively high levels of saponins (which makes them taste bitter) and some other compounds which can cause bellyache, and so these would only be eaten in times of desperation. In addition, many people may find these foods to be strongly laxative the first few times they eat them[1].

Cultivation Details

HabitEvergreen Perennial
Growth—

Agave sisalana is a plant of the drier tropics and subtropics, where it is found at elevations up to 2,000 metres. It grows best in areas where annual daytime temperatures are within the range 15 - 27°c, but can tolerate 10 - 45°c[2]. Younf plants are not frost tolerant, but mature plants can withstand temperatures down to about -5°c[2, 3]. The plant prefers a mean annual rainfall in the range 900 - 1,250mm, but tolerates 500 - 1,800mm[2]. Requires a sunny position in a well-drained soil. Prefers a pH in the range 6 - 7.5, tolerating 5.5 - 8[2]. Plants are very drought tolerant. The plant has escaped from cultivation in many of the areas in which it is cultivated and has become invasive in some areas including several of the Pacific Islands and Australia[4]. Harvesting the leaves for fibre can begin 2 - 4 years after planting, depending on temperature, and usually continues for about 10, occasionally up to 20, years before the plant flowers and dies[2]. The average yield is about 0.9 tonnes/ha of dried fibres[2]. On the best plantations in East Africa, yearly yields of 2.0 - 2.5 tonnes/ha of dried fibres are obtained[2]. Most Agave species are monocarpic, individual rosettes living for a number of years without flowering before sending up an often very large flowering stem and then dying after flowering and setting seed. This species, however, produces a number of new rosettes from suckers or offsets during its lifespan and these new plants will continue to grow after the death of the parent plant. Individual plants take about 7 - 15 years in their native habitat, considerably longer in colder climates, before flowering[5]. Plants produce bulbils along the flowering stem[6]. The roots rarely go deeper than about 35cm[2]. One ton of fibre removes about 30 kg N, 5 kg P, 80 kg K, 65 kg Ca and 40 kg Mg from the field. Because the fibres themselves contain few minerals, the majority of the nutrients can be returned to the land with the pulp[2].

Propagation

Seed - surface sow in a container in a light position. The seed usually germinates in 1 - 3 months at 15 - 20°c[7, 8]. Prick out the seedlings into individual pots of well-drained soil when they are large enough to handle and grow them on in a sunny position until they are at least 10cm tall before planting out. Offsets and suckers can be potted up at any time they are available. Bulbils, where produced, are an easy method of propagation. Simply pot them up and plant out at the beginning of a growing season when they are 10cm or more tall.
