Planning & Planting

Climate & Season Requirements

Eggplants are heat-loving plants that require warm soil and air temperatures to thrive. Understanding their climate needs is essential for successful growth.

Starting eggplant seeds indoors gives them the warm environment they need to germinate

Temperature Requirements

• Soil temperature should be at least 60°F (15°C) for planting
• Optimal growing temperatures: 70-85°F (21-29°C)
• Plants slow or stop growing below 50°F (10°C)

Care and Maintenance

Watering Guidelines

Consistent moisture is crucial for eggplant development, especially during flowering and fruiting stages.

• Provide 1-1.5 inches of water weekly, adjusting for rainfall
• Water deeply at the base of plants to avoid wetting foliage
• Maintain even soil moisture - fluctuations can cause problems like blossom end rot
• Increase watering during hot, dry periods and when fruits are developing
• Consider using soaker hoses or drip irrigation for efficient watering

Watering Tip: Irregular watering can cause misshapen fruits and blossom end rot. Aim for consistent moisture, especially during fruit development.

Fertilizing Schedule

Eggplants are moderate to heavy feeders that benefit from regular nutrition throughout the growing season.

Initial Fertilizing

• Mix compost or aged manure into soil before planting
• Apply a balanced fertilizer (10-10-10) at planting time
• Avoid high-nitrogen fertilizers which promote leafy growth at the expense of fruit

Ongoing Nutrition

• Side-dress with compost or balanced fertilizer when first fruits appear
• Apply liquid fertilizer every 2-3 weeks during fruiting
• Consider calcium supplementation if blossom end rot appears

Mulching Benefits

Proper mulching helps maintain soil temperature, conserve moisture, and reduce weed competition.

• Wait until soil has fully warmed before applying mulch
• Apply 2-3 inches of organic mulch like straw, shredded leaves, or compost
• Keep mulch a few inches away from plant stems to prevent rot
• Black plastic mulch can help warm soil in cooler regions
• Replenish mulch as needed throughout the growing season

Support & Pruning

Eggplants benefit from support as they grow and can be pruned to improve air circulation and fruit production.

Support Methods

• Install stakes or cages at planting time
• Choose supports at least 24-36 inches tall
• Secure plants to supports with soft garden ties
• Ensure supports are sturdy enough to hold fruit-laden plants

Optional Pruning

• Remove lower leaves that touch the soil
• Prune to 2-3 main stems for larger varieties
• Remove suckers (shoots that grow in leaf axils) for better air circulation
• Pinch growing tips when plants reach desired height

Pollination

Eggplants are self-pollinating, but they can benefit from some assistance, especially when grown in enclosed spaces.

• Most eggplants are pollinated by wind and insects
• Gently shake plants during flowering to help distribute pollen
• Plant flowers nearby to attract pollinators
• Avoid using insecticides during flowering to protect beneficial insects

Growing Eggplant in Containers

Eggplants are excellent candidates for container growing, making them accessible even to gardeners with limited space.

Container Selection

• Choose containers at least 5 gallons (12 inches) in size
• Ensure containers have adequate drainage holes
• Dark-colored containers absorb heat, warming the soil
• Self-watering containers can help maintain consistent moisture

Best Varieties for Containers

• Fairy Tale - Compact plants with small, striped fruits
• Patio Baby - Dwarf plants producing small, egg-shaped fruits
• Little Fingers - Produces clusters of slim, finger-sized fruits
• Hansel - Compact plants with clusters of slim purple fruits

Container Growing Tips

• Use high-quality potting mix with added compost
• Place containers in a location receiving at least 6 hours of sun
• Water more frequently than in-ground plants as containers dry out faster
• Fertilize every 2 weeks with a balanced liquid fertilizer
• Provide support even for compact varieties
• Move containers to protected areas during extreme weather

Container Tip: In cooler climates, containers allow you to start growing earlier by bringing plants indoors during cold nights.

Harvesting & Storage

Knowing when and how to harvest eggplants ensures you'll enjoy them at their peak flavor and texture.

When to Harvest

Timing is crucial when harvesting eggplant - pick them too early and they'll be underdeveloped; too late and they become bitter and seedy.

• Harvest when fruits are firm, glossy, and have reached the expected size for their variety
• The skin should "bounce back" when gently pressed with your thumb
• Cut open a test fruit - seeds should be visible but not dark and hard
• Most varieties are ready 65-80 days after transplanting
• Smaller varieties are typically harvested when 3-4 inches long
• Standard varieties are usually harvested at 6-8 inches

Overripe eggplants develop a dull appearance, become spongy, and taste bitter. Harvest promptly when fruits reach maturity.

Troubleshooting Common Issues

Why are my eggplant flowers dropping without forming fruit?

Flower drop is commonly caused by:

• Temperature extremes (below 55°F or above 95°F)
• Insufficient pollination
• Drought stress or inconsistent watering
• Excessive nitrogen fertilizer promoting leaf growth over fruit

Try hand-pollinating flowers, maintaining consistent watering, and providing afternoon shade during extreme heat.

Why are my eggplant leaves turning yellow?

Yellowing leaves can indicate several issues:

• Nutrient deficiency (especially nitrogen)
• Overwatering or poor drainage
• Pest infestation (check leaf undersides)
• Disease (verticillium or fusarium wilt)
• Natural aging of lower leaves

Examine the pattern of yellowing and check for other symptoms to determine the specific cause.

Why are my eggplants bitter?

Bitterness in eggplants can be caused by:

• Overmaturity - harvest when younger
• Heat or drought stress
• Variety (some are naturally more bitter)
• Inconsistent growing conditions

To reduce bitterness, harvest at peak ripeness, maintain consistent watering, and consider salting cut eggplant and letting it sit for 30 minutes before cooking.

Why are my eggplants small?

Undersized fruits may result from:

• Insufficient nutrients (especially phosphorus and potassium)
• Too many fruits on one plant (consider thinning)
• Insufficient sunlight
• Pest or disease stress
• Variety (some are naturally small)

Feed plants with a balanced fertilizer, ensure adequate sunlight, and remove some fruits to allow others to grow larger.
