Days to Maturity: 95-120 days for maturity from direct sow.

The amount of rain that falls during the week affects how much you should water your garden. Keep soil consistently moist until bulbs enlarge and mature. Onion roots are shallow; so a light watering will suffice.

Large bulbs have a glistening white skin and mild sweet flesh.
