Basil leaf curl treatment is dependent on the specific factor causing it. Here are the most common stressors leading to curling basil leaves:

• Sunlight – Basil is definitely a sun-loving plant and exposure to less than six hours of bright light per day may result in distorted foliage or basil leaves small and curled.
• Relocating the plant to a sunnier location may solve the problem. Water: Too much or too little.
• Basil requires regular water, but not too much. As a general rule, water the plant deeply whenever the top 1 to 2 inches (2.5-5 cm.) of soil feels dry to the touch, usually once every four to seven days.
• However, keep in mind that potted plants may require more frequent irrigation, especially during hot, dry weather.
• Whether the plant is in the ground or in a container, be sure the soil (or potting mix) is lightweight and drains well. Water at the base of the plant and keep the leaves as dry as possible.
• Diseases-Fungal diseases may be the cause of basil leaves curling up, but chances are, you’ll notice other telltale signs. For example, powdery mildew is a fungal disease that causes a grey, powdery substance on the leaves.
• The disease is caused when conditions become too moist, including too much shade or soggy soil.
• Fusarium wilt, which is usually deadly, can cause brown or distorted leaves. To prevent moisture-related diseases, water basil carefully as directed above.
• Pests – Basil is a hardy plant, but it can sometimes be bothered by aphids and other small, sap-sucking pests such as spider mites or scale.
• The pests can be difficult to see, but a close look at the leaves, especially the undersides, will usually tell the tale. If you determine your plant is infested with bugs, insecticidal soap spray usually keeps the pests in check.
• Be sure to spray when the foliage is in the shade, otherwise, the spray may scorch the plant. Don’t spray when the temperatures are above 90 degrees F. (32 C.).

Le piante medicinali aromatiche sono coltivate principalmente per le foglie, gli steli, le cortecce, i fiori o i componenti dei frutti commestibili e sono agenti aromatici e/o ayurvedici essenziali usati principalmente nei paesi dell'Asia meridionale. Anche il tulsi e il basilico appartengono al gruppo delle piante medicinali aromatiche, e condividono profili di gusto e caratteristiche simili. Di conseguenza, il tulsi è spesso chiamato basilico o viceversa dalla maggior parte dei consumatori nel mondo. Ma il tulsi e il basilico sono due piante diverse, il nome botanico del tulsi è Ocimum tenuiflorum mentre il nome botanico del basilico è Ocimum basilicum.
