Citrus farming weather in Cap Bon
The 20,000 hectares of Cap Bon citrus, led by the Maltaise orange, rest on a frost-sensitive fruit: at 0 °C ripe pulp is already affected, and the Maltaise is picked precisely from December to February. At the other end of the year, flowering in March-April and the physiological drop in May-June call for a steady water supply drawn from an aquifer already exposed to seawater intrusion. This page tracks frost, water and spraying windows for Nabeul, Grombalia and Menzel Temime.
Frequently asked questions
- At what temperature does citrus freeze?
- Ripe fruit is affected from 0 °C and damage becomes severe below -2 °C, especially on clear, windless nights when ground-level temperature falls below the sheltered reading. This page flags the risk three steps before that threshold.
- When should Cap Bon citrus be irrigated?
- Needs peak from fruit set through fruit growth, May to September. The water balance on this page compares evapotranspiration adjusted by a crop coefficient of 0.70 with the last seven days of rain, and gives the deficit in mm and in m³ per hectare.
- What conditions suit spraying in a citrus orchard?
- Wind between 3 and 19 km/h, no rain within the following six hours and a Delta T between 2 and 8. The hourly window on this page marks those slots over 48 hours for the Cap Bon area.
