Solanum insanum

Eggplant needs a large amount of sunlight to grow best, though it can tolerate locations with somewhat reduced—but still considerable—sun exposure. This level of light promotes healthy growth. Excessive sun can scorch the leaves, while too little sunlight can reduce fruiting. Having originated in sunny environments, it can pass through its various growth stages if given sufficient light.

Eggplant is adapted to a native growing environment with temperatures between 68 and 95 °F (20 to 35 ℃). That range represents its preferred temperatures. Seasonal temperature changes for eggplant depend on the local climate but should remain within its preferred temperature span.

To feed eggplant, apply natural or commercial fertilizer high in nitrogen for leaf growth, phosphorus for roots and blossoms, and potassium to support photosynthesis and maximize fruit production. Plant in spring, amend the soil with compost or manure, and fertilize seedlings once they reach 2–4 inches in height. A shortage of macronutrients causes slow growth, wilting, and problems with fruit quality.

When repotting Eggplant, select a pot 1–2 inches (2.5–5.1 cm) larger with ample drainage. Use a well-draining potting mix. Repot in spring or fall, ensuring the root ball is slightly lower than the rim of the flower pot. Water thoroughly after repotting and place in a warm spot with indirect sunlight.
