Ideal conditions for growing eggplants
For successful cultivation, it is important to consider some environmental factors:
- Temperature: Eggplant prefers warm temperatures, between 23 ºC and 25 ºC on average during its development. It can tolerate temperatures up to 40°C if the humidity is optimal, but it is very sensitive to frost.
- Light: require between 10 and 12 hours of daily lightIn regions with little sunlight, it is advisable to use artificial lighting to avoid problems with fruit growth.
- Ground: It is not very demanding, but it is advisable to avoid clayey or overly acidic soils. Ideally, work with a fertile, well-drained soil with organic matter.
When to plant eggplants
Sowing is preferably done between January and April, depending on the climate of your area. It is advisable to start growing in protected seedbeds, as winter temperatures may be too cold for effective germination.
