This page has general information for commercial citrus growers in the Northern Territory (NT).
The citrus crops grown commercially in the NT include lemons, limes, red fleshed grapefruit, mandarins and pummelo.
You must comply with current quarantine entry conditions if you want to import citrus trees from interstate.
The lack of cold nights in the NT causes erratic flowering in many citrus varieties. Flowering in some varieties can be forced through moisture stressing or droughting after the wet season.
The red fleshed grapefruit is grown successfully in Katherine and Darwin.
Ray and Henderson varieties are the most productive in the Top End, although Rio and Flame varieties have better colour.
Lemons are grown in the Darwin and Katherine regions.
Eureka and Lisbon are the main commercial varieties. Lisbon tends to do better in dry areas.
