Safety & Hazards

Although no individual reports regarding this species have been seen, there have been cases of poisoning caused by the consumption, in large quantities and by some mammals, of certain members of this genus. Dogs seem to be particularly susceptible[1].

Growth—

Allium fistulosum is a very cold-tolerant plant that originated in the temperate zone and is widely grown there. Plants will often retain their leaves even when covered in snow[2]. In the tropics, it can be grown successfully at elevations between 1,000 - 2000 metres. High temperatures encourage bulb formation, but flower formation and seed production are only possible where the bulbs are subjected to low temperatures. In the tropics, flower and seed formation will therefore only occur at higher elevations[3]. The plant grows best in areas where annual daytime temperatures are within the range 12 - 25°c, but can tolerate 6 - 30°c[3]. It prefers a mean annual rainfall in the range 850 - 1,600mm, but tolerates 700 - 2,500mm[3]. An easily grown plant[4], it prefers a sunny position in a light well-drained but moist soil[5, 3] but tolerates most soils[5, 6] including those that are damp and acid[4]. Prefers a pH in the range 6.5 to 7.5[2], but it tolerates a pH in the range 4.9 to 8.5. Average yields of leaves may be 34-45 t/ha[3]. The oriental forms of this species, known as bunching onions, tend to be hardier and more robust than the welsh onion[2]. There are two basic forms, multi-stem types and single-stem types. The single-stem types divide less freely than the multi-stems[2]. The plants are often eaten by slugs[PFAF]. The bulbs should be planted fairly deeply[5]. Most members of this genus are intolerant of competition from other growing plants[4]. The plant probably arose through cultivation from Allium altaicum[4].

Propagation

Seed - sow spring in a greenhouse. The seed germinates over a wide range of temperatures, it is faster at higher temperatures[2]. Prick out the seedlings into individual pots when they are large enough to handle. When well-grown, the plants should be ready to be planted out in the summer. If they are not large enough at this time, grow them on in the greenhouse for their first winter and plant them out in late spring. Division of the plants is very easy and can be done at almost any time of the year though the spring is probably best. The divisions can be planted out straight into their permanent positions if required.
