Care
Light exposure
Place Solanum angustifolium in full sun to encourage abundant flowering and optimal fruit production. A minimum of 6 hours of direct daily sunlight is needed. Partial shade is tolerated but slows growth.
Regular watering
Water moderately and regularly, keeping the soil moist but not waterlogged. Reduce watering in winter or during dormancy. Avoid stagnant moisture which promotes fungal diseases.
Well-draining soil
Prepare rich, light and well-structured soil enriched with organic matter. A neutral to slightly acidic pH is suitable. Ensure effective drainage to prevent root asphyxiation.
Balanced nutrition
Apply a balanced fertilizer every 2 to 3 weeks during the active growing period. Choose a formula with good potassium content to support flowering and fruit production.
Maintenance pruning
Pinch the tips of young shoots to encourage bushy branching. Remove spent flowers to extend flowering. Eliminate dead or damaged wood as needed.
Pest prevention
Watch for whiteflies, mites and aphids, which are common on Solanaceae. Keeping foliage dry and ensuring good air circulation reduce the risk of powdery mildew or rot. Isolate any affected plant.
