The Allium jisiulosum , or Welsh Onion, is cultivated for 
spring salad ; it forms no bulbs, but is very hardy. If the 
seed be sown early in September in rich ground, although 
the tops may die down in the winter, yet the roots will con- 
tinue sound, and put up new leaves early in the spring. 
The Allium cepa, or common White and Red Onions, are 
most generally cultivated by market gardeners as a substitute 
for the Allium Jisiulosum ; they sow the seed in the spring 
and autumn months, the product of which is pulled and sent 
to the market while young, and generally meets with a ready 
sale. 
The Allium prolijerum, or Tree Onion, is propagated by 
planting the bulbs in spring or autumn, either the root bulbs, 
or those produced on the top of the stalks ; the latter, it 
planted in the spring, will produce fine Onions. These may 
be planted in rows with a dibble, the same as Shallots. 
The Potato Onion, Allium tuberosum, does not produce 
seed as other Onions, but it increases by the root. One sin- 
gle Onion, slightly covered, will produce six or seven in a 
clump, partly under ground. 
The bulbs are generally planted in the spring, from twelve 
to eighteen inches apart, but they will yield better when 
planted in autumn, as they will survive the winter if slightly 
covered with dung, litter, or leaves of trees, &c.
