Shallot (Allium ascalonicum)
As the Latin name implies, this species of onion comes from the vicinity of the city of Ascalon in Asia Minor, where it was grown since ancient times.
Currently, varieties that produce yellow or purple-red bulbs are grown. Yellow varieties are grown on a large scale in the Netherlands; purple-red varieties, also known as German shallots, come from Russia. They form hard bulbs and perform well in sandy soils. Under the shallots, similar to an onion, no fresh manure is given, however, small doses of composted chicken or guano can be used. Shallots are very susceptible to viral diseases and gray mold, which is probably related to the only vegetative way of reproduction of this plant. The small shallots can be planted in September and October, but due to the possibility of freezing it is better to do it in March. It is usually planted at spacing 25 x 15 cm.

Like shallots, it can be planted in early fall and left in the field throughout the winter. Every 2-3 years a seven-year-old should be transplanted. The dug out clumps of elongated bulbs are divided, The bulbs are sorted by size and the largest bulbs are re-planted in early August at intervals 30 cm.
