Before you plant
These conditions determine whether it will thrive.
Cold hardinessCover in a hard freeze
Handles normal frost like onions do. Cover in a hard freeze.
Heat toleranceShade from late-afternoon sun
Bulbs finish as days warm and lengthen. Expect to harvest around May in Phoenix as tops die back.

Light
Sun exposure
Full winter sun; give leafy crops afternoon protection during warm fall and spring weather.
Water
Irrigation
Keep the vegetable root zone evenly moist with regular irrigation; adjust to rain, soil, and temperature rather than using a fixed summer schedule.
Planting & stewardship
How to help Shallot thrive
1
Prepare a fertile, well-drained bed and keep seed or transplants evenly moist through establishment.
2
Thin to the final spacing; crowding reduces harvest quality.
3
Watch for aphids and caterpillars and protect sensitive growth from a hard freeze.
4
Harvest before sustained spring heat causes bolting or poor quality.
