Step-by-Step Planting Guide

1Choose container and variety

Select 5-10 gallon container with drainage. Choose compact varieties: Fairy Tale, Patio Baby, Hansel, Gretel, or any Asian types. One plant per container.

2Prepare rich soil

Fill with nutrient-rich potting mix. Eggplant are heavy feeders like tomatoes and peppers. Mix in compost and slow-release fertilizer.

3Wait for warm weather

Transplant only after all frost danger and when nights stay above 55°F. Eggplants need warm soil (70°F+) and warm air to thrive.

4Position in full sun

Place in hottest, sunniest location - eggplants need 8+ hours of sun and love heat. Reflected heat from walls helps.

5Water consistently

Keep soil evenly moist - 1-2 inches per week. Eggplants don't tolerate drought. Mulch to retain moisture.

6Support and stake

Install stake at planting. Tie main stem as it grows. Support branches bearing fruit to prevent breakage.

7Harvest at right time

Harvest when skin is glossy and fruit gives slightly when pressed. Cut don't pull - use scissors. Overripe fruit has dull skin and bitter flavor.

Frequently Asked Questions

What size container for eggplant?
Eggplant needs minimum 5-gallon containers, ideally 7-10 gallons. Larger containers produce bigger yields. One plant per 5-gallon container. Compact varieties can manage in 5 gallons; full-size varieties need 7+ gallons.
How many eggplants per plant?
Expect 4-8 eggplants per container plant for standard varieties, 10-15+ for smaller Asian varieties. Container yields are slightly lower than ground-grown plants. Adequate sun, water, and fertilizer maximize production.
Do eggplants need support?
Yes, most eggplants benefit from staking, especially once fruit sets. Heavy fruit can break branches. Use a stake or small tomato cage. Asian long eggplants especially need support due to heavy fruit clusters.
Why aren't my eggplant flowers setting fruit?
Eggplant flower drop is usually caused by: 1) Temperature stress - below 60°F or above 90°F, 2) Inconsistent watering, 3) Low humidity, 4) Poor pollination - tap flowers daily to release pollen, 5) Too much nitrogen fertilizer.
