Georgia Rattlesnake

Onion

90d to harvest

Sweet and richly aromatic, Georgia Rattlesnake onions bring a gentle, honeyed flavor with a crisp, juicy bite that stays tender from garden to table. The bulbs mature in about 90 days with an eye-catching, elongated silhouette and distinctive “rattlesnake” striping—golden-brown skins over a pale, succulent interior. Grow them for fresh slicing, standout salads, and caramelizing-style sweetness in sauces and roasts, where their mild character shines.

Frequently Asked Questions

What pest or disease most often affects Allium cepa (Georgia Rattlesnake onions), and how can I manage it?

Onions commonly suffer from onion maggots and thrips, and they can also develop downy mildew when weather is cool and wet. Inspect weekly for maggots at the base of plants and use row cover over seedlings to prevent egg-laying; remove and discard heavily infested leaves to slow spread. If downy mildew appears (grayish/pale lesions with a fuzzy look), improve airflow, avoid overhead watering, and remove affected foliage right away.

How often should I water Georgia Rattlesnake onions during active growth?

During bulb formation, keep the soil consistently moist but not waterlogged—typically about 1 inch (2.5 cm) of water per week, split across 1–2 waterings depending on heat. Water deeply to reach the root zone, then let the top 1 inch of soil dry slightly before watering again. Stop heavy watering once bulbs start enlarging and the tops begin to fall over, so they can cure instead of staying wet and prone to rot.
