Eggplants require warm to hot weather throughout the season for good production. Hot caps or row covers can be used to elevate temperatures. Planting in a container will also help in absorbing heat.
Cultural tips for growing eggplant, UC IPM
Planting
- Transplant 18 inches apart in May to June.
- For best results, wait until daytime temperatures are regularly over 75°F.
- If growing your own seedlings, start the seeds 8 weeks before you want to plant.
- Stake or cage plants to prevent branches from breaking due to fruit production and to keep the fruit off the soil.
- Hand pollinate by shaking the flowers to improve the fruit set.
Harvesting
- In August to October, two to three months after transplanting, depending on variety.
- Harvest when the flesh is glossy and gives slightly under thumb pressure. Use a pruning shears or knife to clip the stem. Watch out for possible thorns on the calyx.
- Don’t leave mature fruit on the plants because it will suppress new fruit production.
