Care Guide
How to Water
Water every 2-3 days, keeping soil slightly moist but well-drained. Avoid overwatering — excess moisture promotes root rot and downy mildew. Water in the morning at the base of the plant.
Lighting
Requires full sun for at least 6 hours daily. Indoors, place near south-facing windows or use grow lights. Insufficient light produces small, flavorless leaves.
Ideal Soil
Use light, fertile, well-draining soil with pH between 6.0 and 7.5. Add organic matter to enrich. Avoid heavy clay soils that retain excess moisture.
Recommended Pot
Terracotta or ceramic pots with drainage holes are ideal. A 15-20 cm pot is sufficient for an individual plant. Avoid oversized pots that retain too much moisture.

Common Problems
Downy Mildew
Downy mildew is a fungal-like disease caused by oomycetes (water molds) that thrives in cool, wet conditions. It affects a wide range of plants, causing yellowing leaves with fuzzy white-gray growth underneath, leading to defoliation and reduced yields if left untreated.
Fusarium Wilt
Fusarium wilt is a serious fungal disease caused by the soil-borne fungus Fusarium oxysporum. The fungus invades roots and blocks the water-conducting vessels (xylem) of the plant, causing progressive wilting and eventual death. Host-specific forms of the pathogen exist that attack different plant species.
Aphids
Aphids are small, soft-bodied, pear-shaped insects (1/16 to 1/8 inch long) that feed by sucking nutrient-rich sap from plants. They reproduce rapidly and can quickly weaken plants, causing distorted growth and transmitting plant viruses. Aphids come in various colors including green, black, red, yellow, brown, and gray. They secrete honeydew, a sticky substance that attracts ants and encourages sooty mold growth.
Bacterial Leaf Spot
Bacterial leaf spot is a plant disease caused by bacteria in the Xanthomonas and Pseudomonas genera that affects various ornamental and edible plants. The bacteria infect leaves through wounds or natural openings, causing characteristic lesions that can lead to premature leaf drop and plant weakening.
Meaning & Symbolism
Symbol of love and protection in many cultures. In Hindu tradition, it is the sacred Tulasi plant, representing the goddess Lakshmi.
