🍊 The great orange flip: Florida vs California

For most of a century, “orange” meant Florida. Today California grows the most. What flipped it? A bug smaller than your fingernail.

✅ What we know (fact)

Florida led America in oranges for decades — most of its oranges are squeezed into juice, while California mostly sells fresh oranges to eat.

Basis: USDA citrus reports: the juice/fresh split between Florida and California is long documented.

✅ What we know (fact)

In 2005, a sickness called citrus greening was found in Florida. A tiny insect (the Asian citrus psyllid) carries it from tree to tree. Sick trees make small, bitter fruit and slowly die — and there is still no cure.

Basis: USDA: citrus greening (HLB) detected in Florida in 2005; no cure exists yet.

✅ What we know (fact)

Hurricanes have also battered Florida's orange groves in recent years, knocking fruit off trees and flooding fields.

Basis: Widely reported hurricane damage to Florida citrus (e.g., Hurricane Ian, 2022).

🤔 What people think (hypothesis)

Will Florida oranges come back? Scientists are testing greening-resistant trees and new protections — some growers are hopeful, but nobody knows yet.

※ A hypothesis is an idea that isn't proven yet.
