Shallots like to be grown in the same
soil conditions as onions, that is, rich, loamy soil with good
drainage. If your soil is sandy or clayey you should amend it before
planting with compost or manure. Shallots like lots of phosphorous
and potassium but not too much nitrogen, so good fertilizers to add
at the time of planting are bone meal, fish bone meal, or rock
phosphate for phosphorous, and kelp meal, wood ashes or greensand for
potassium.
Shallots like to develop their
spearlike leaves when the weather is cool, followed by warmer weather
for the development of the bulb portion of the plant. If you live in
a northern climate and plant in the fall you should protect the
shallots with a layer of mulch. If you live in a mild winter climate
plant in the fall through early spring.
Plant individual cloves broad end
down, about two inches deep and six inches apart. Plant in rows or
beds. Keep soil moist throughout the growing season. Control weeds to
prevent competition, and feed with a balanced organic fertilizer when
the tops are about six inches tall and the bulbs begin to
swell.
Shallots are ready to harvest when
the tops begin to fall over and wither. Cure them for several days
outdoors where there is good air circulation out of direct sunlight.
When the bulbs are dry store them in a cool, dry place by braiding or
hanging in a string bag.
