Shallot : Shallot

Mild and delicate onion flavored bulbs, easy to grow, productive

Some gourmets consider the shallot to be the most refined of all the Allium family, as it is milder and more delicately flavored than the onion or garlic. It has similar requirements as the onion and is grown in the same way, though it is somewhat easier to grow. It works very well in small gardens, as it doesn't take up much space and is quite productive.

Fusarium Bulb Rot

Fusarium oxysporum sp. cepae

Also known as Fusarium Basal Rot, this is a variety of Fusarium that specifically attacks members of the Allium family (onion, garlic, shallot and chive). The fungus gets into the bulb through small wounds (these may be caused by tools, insects or onion maggots) and enters the leaves, causing them to turn yellow, wilt and die back at the tips. It then moves down into the neck and bulb, making them soft and squishy (a white fungus may be visible at this point). Often the bulb doesn’t show any symptoms until after harvest.

Remove and destroy infected plants. Keep onion maggots under control as their damage often allows the fungus to enter the bulb. Some varieties are resistant. Store the bulbs in a cool, dry place after harvest.
