What is causing black patches on my basil leaves
They are growing in the sun, in a pot.Should they be in the shade? No sign of insects.
Basil likes a warm sunny position preferably without a saucer underneath the pot. They are prone to leaf spot so water early in the morning. It is an annual plant and will not grow during the cooler winter months. Sometimes too much water can also cause a browning of the leaf edges. I have attached a link to the Yates website on growing basil. Herbs
