How to Take Care
Proper care is essential for maximizing the growth and productivity of Italian Large Leaf Basil. Follow these guidelines to ensure a healthy and thriving plant:
Sunlight Requirement
Italian Large Leaf Basil requires full sun for optimal growth and leaf production, although it can tolerate partial shade. Ensure the plant receives at least 6-8 hours of sunlight daily to promote vigorous growth.
Fertilizer
Apply a balanced, organic fertilizer every 4-6 weeks during the growing season to support robust growth and abundant leaf production. Regular feeding helps maintain the plant’s vigor and enhances its aromatic qualities. Learn more about NPK fertilizers to optimize nutrition.
Water Requirement
Water the plant regularly to keep the soil consistently moist, especially during dry spells. Avoid letting the soil dry out completely, as this can stress the plant and reduce its productivity. Consistent moisture levels are crucial for healthy growth. Consider using a slow drip watering system to maintain the right moisture level. Learn how often you should water your plants for the best results.
Mulching
Apply organic mulch around the base of the plant to retain moisture, suppress weeds, and regulate soil temperature. Mulching helps create a stable environment for the roots, promoting healthy growth and preventing water evaporation.

Its strong aroma can help repel pests such as aphids, mosquitoes, and whiteflies, benefiting nearby plants and enhancing garden biodiversity.

Harvesting
Begin harvesting when the plant reaches about 6-8 inches in height.
