Highlights
The pale green fruits with their distinctive white striping make Thai Round Eggplant visually striking in the garden and on the plate. At just 2 ounces each, these miniature eggplants are ideally sized for individual portions, making them especially useful for pickling and preserving. The plant's natural resistance to disease combined with its quick maturity and compact 30 to 36 inch height means you can grow productive plants in almost any climate zone and with minimal fussing.
Common Uses
Thai Round Eggplants excel in pickling, where their small size and firm texture make them ideal for whole preservation in jars. The diminutive fruits are also excellent sliced and fried, roasted whole, or added to curries where their tender flesh absorbs flavors well. Their miniature proportions make them suitable for serving whole as individual portions in restaurant-style plating or as an elegant addition to vegetable platters.

Care Instructions
Start Indoors
Start seeds indoors 6 to 8 weeks before your last expected spring frost, sowing them 1/4 inch deep in warm soil maintained at 75 to 85 degrees Fahrenheit. Provide consistent moisture and warm conditions, as eggplant seeds germinate slowly compared to other vegetables. Seedlings will be ready to transplant outdoors once they develop their second set of true leaves.
Transplant Outdoors
Transplant seedlings outdoors after all danger of frost has passed and soil temperatures have warmed to at least 60 degrees Fahrenheit, ideally closer to 70. Harden off seedlings by gradually exposing them to outdoor conditions over 7 to 10 days. Space plants 18 inches apart in rows 24 inches apart, planting them at the same depth they grew in containers.
Harvesting
Harvest Thai Round Eggplants when they reach 2 inches in diameter and the skin develops a glossy finish, typically 50 to 59 days after transplanting. The fruits should feel firm when gently squeezed and the skin color should be a pale to medium green with white striping. Use a sharp knife or pruners to cut the fruits from the stem rather than pulling, which can damage the plant. Continuous harvesting encourages the plant to produce more fruits throughout the season.
Pruning
The bush growth habit requires minimal pruning, but removing the lowest leaves once plants are established improves air circulation and reduces disease risk. Pinching out the top growing tip when plants reach 12 inches tall encourages bushier growth and more productive branching. Remove any dead or yellowing leaves throughout the season.
