Shallots grown from seed will only produce a single bulb. On rare occasions two bulbs may be produced.
Choose a sunny position where the soil is well drained. Dig the area in the autumn incorporating well rotted manure or garden compost. Approximately seven days prior to planting or sowing apply a vegetable fertilizer.
For early crops sow the shallot seeds during February and March in greenhouse or indoors at a temperature of 15-20ºC (60-68ºF). Grow on the resulting seedling in trays, planting outdoors during May and June. Space the plants 7.5cm (3") apart in the row and 30cm (12") between rows.
Sow the seed direct outdoors between March and May. Sow the seed in to finely raked, firmed soil at a depth of 1cm (½″).
Harvest and dry the bulbs once the foliage has turned yellow.
