Onion and nurseries
Onion is the great crop of the Sahel — and the greenhouse plays a precise role: successful nurseries. Healthy, uniform seedlings protected from rain or heat make all the difference at transplanting.
The keys to success
- Sow in a nursery under cover: even emergence, seedlings protected from beating rain.
- Light shading helps emergence during the hottest periods.
- Water finely and regularly: young onion seedlings do not forgive drought.
- The greenhouse also serves tomato, pepper and cabbage nurseries: a good seedling makes a good crop.
