member of allium family.  fairly disease and pest resistant  Originating in central Asia before being adapted to various climates

Fun Facts


Downy Mildew – Grey or purple spots on leaves. Leaves appear pitted. Usually occurs in wet weather. Improve air circulation and drainage.Heavy top growth/Leaf droop – Too much Nitrogen or manure.

Soft Bulbs – Excess Nitrogen

Botrytis, grey mould – soft roots with grey or brown mould – more common in storage) Store in dry well ventilated conditions.

Bulbs split at base – heavy rain or watering after a prolonged dry spell. Water frequently in dry weather.

Bolting/Running to seed – seed sown at the wrong time. Sow correct variety at the correct time.
