Safety & Hazards

One report suggests that the raw fruit contains hallucinogens[1]. This fruit is frequently eaten in various parts of the world, there are even some named varieties, and no such effects have been mentioned elsewhere, nor observed by the writer when he has eaten the fruit. Possibly the unripe fruit was being referred to in the report, though even this would be surprising[PFAF].

Cultivation Details

HabitDeciduous Tree
GrowthMedium

A plant of the subtropics and warm temperate zones, it can also be cultivated in the tropics at elevations between 300 - 3,300 metres[2]. It grows best in areas where annual daytime temperatures are within the range 20 - 28°c, but can tolerate 13 - 45°c[2]. The plant becomes dormant below 13°c[2]. When dormant, the plant can survive temperatures down to about -5°c, but young growth can be severely damaged at 1°c[2]. It prefers a mean annual rainfall in the range 700 - 2,500mm, but tolerates 300 - 5,100mm[2]. Grows best in a sunny position, tolerating light shade[3, 4, 2]. Succeeds in a variety of soils ranging from sandy loam to clayey loam, but it prefers a deep, alluvial, loamy soil with sufficient moisture[3, 4, 5, 2]. Prefers a pH in the range 5.5 - 7.5, tolerating 4.3 - 8.3[2]. Plants are fairly wind-resistant[6], though the branches are often killed back when growing in strong maritime exposure[PFAF]. The species is not drought resistant, though at least some cultivars are - the form 'Tatarica' has been especially mentioned[7]. Mulberries have brittle roots and so need to be handled with care when planting them out[8]. Any pruning should only be carried out when the plant is fully dormant because mulberries bleed badly when cut[8]. Ideally prune only badly placed branches and dead wood[8]. This is a good tree for growing grapes into[9]. The grapes are difficult to pick but always seem to be healthier and free from fungal diseases[10]. Plants in this genus are notably resistant to honey fungus[6].

Propagation

The seed germinates best if given 2 - 3 months cold stratification[11, 12]. Sow the seed as soon as it is ripe if possible, otherwise in late winter in a cold frame. The seed usually germinates in the first spring, though it sometimes takes another 12 months. Prick out the seedlings into individual pots when they are large enough to handle and grow them on in the cold frame for their first winter. Plant them out in late spring or early summer after the last expected frosts. Cuttings of half-ripe wood, 7 - 10cm with a heel, mid summer in a frame. Plant out in spring. A good percentage take, though they sometimes fail to thrive[13, 14]. Cuttings of mature wood of the current season's growth, 25 - 30cm with a heel of 2 year old wood, autumn or early spring in a cold frame or a shady bed outside[13, 14, 6]. Bury the cuttings to threequarters of their depth. Layering in autumn[6].
