Rockmelon (called cantaloupe outside Australia/NZ) is a warm-season melon requiring long hot summers for sweet fruit. Australia is a major commercial rockmelon producer. Success depends on sustained warmth, good drainage, and bee pollination. Best in arid and subtropical zones; marginal in cool-temperate.
