Water well to moisten the soil to a depth of at least 6 inches so the soil is moist but never soggy. Consistent watering is best, and a soaker hose or drip system at ground level is ideal.
The critical period for moisture is during fruit set and fruit development. Strangely shaped eggplants result from inconsistent or inadequate watering.
Mulching can help to provide uniform moisture, conserve water, and reduce weeds.
Apply a balanced fertilizer every 2 weeks or so.
Note: Too much nitrogen may cause excessive vegetative growth. If you are using plastic mulch, apply fertilizer through drip irrigation, or apply fertilizer to the side of the row.
For bigger fruits, restrict to five or six per plant, pinching off the extra flowers that develop.
Eggplant may fall over once loaded with fruit! Be sure to stake tall plants or use a cage to keep the plants upright. If growing eggplant in containers, stake the stems before the fruit forms.
For a bushier plant, pinch out the terminal growing points, the central points on a plant from which new shoots and leaves grow. Look for the newest (and usually smallest) leaves at the center of the plant and pinch out the bud forming there.
Eggplants are susceptible to temperature fluctuations: Cool nights (below 55ยฐF/13ยฐC) or hot days (above 95ยฐF/35ยฐC) can cause poor fruiting. Cover plants on cold nights and provide shade (e.g., a beach umbrella) on hot, sunny days. Cold also impairs ripening.
