Plant about 18 inches apart and stake if you don’t want the heavy fruit to pull the plants down.  Harvest when the are plump but don’t wait until they are too large.  They may not get to the size you are used to seeing in the supermarket.

Eggplants are tender, and cold weather may weaken them. Use row covers for a real boost in performance and insect control. Remove when plants reach the covers or when blossoms first appear. Space transplants 18″ apart in rows 30-36″ apart, or 2 rows on poly mulch, 18-24″ between plants.
