In my experience with sweet basil, it tends to go hopelessly into flower long before it gets a chance to develop black spots in its leaves from cold. If you have a perennial basil plant, it can tolerate lower temperatures, but it is a good idea to move it indoors when it gets colder than 50☏ as they tend to get very yellow or die. This is because the plant struggles to move nutrients from its roots at lower temperatures, and also because the leaves can actually just die. If your temperatures drop below 50☏ or so, the leaves will turn purple and then black. If your basil plant is not healthy, its ability to protect itself with these compounds is compromised, and the result is that it will become diseased, and not taste very good! A common symptom of a diseased basil plant is black spots on the leaves. Terpenes are highly bioactive biological compounds with strong anti-fungal, anti-bacterial and anti-insect properties. These bees are crucial for my winter fava bean crop.īasil is a plant that produces a number of terpene flavor compounds, including linalool, eugenol, forms of cineole, limonene, and various others depending on the cultivar. It is a strong winter flower source to keep leaf cutters and other bees active. I live in a relatively mild climate, so I plant perennial basil all over the garden to keep pollinators alive. The annual basil is your summer treat, and the perennial provides you with fresh basil in winter – if you live in a colder zone, you can grow perennial basil year-round indoors – as long as you give it a bit of supplemental lighting. These perennial basil plants are never quite as yummy as the annual cultivars, so, I advise growing both. However, there are many hybrid basil cultivars that have been bred that are hybrids between annual and perennial basil, and these produce perennial cultivars that can be grown from cuttings -they generally do not produce seeds. There are however many many other species of Osimum that are grown, and in some cases can be hybridized to yield all sorts of interesting “basil plants”.īasil is generally an annual plant – this means that it grows in spring, produces leaves that you can eat in summer, and then flowers in fall and produces seeds and dies. More often than not, when we refer to basil we refer to one of the many cultivars of Ocimum basilicum. Read on to find my tips on how to achieve this. Black spots on basil leaves are a common problem, and if you know how to avoid them, you will have a year-round supply of basil leaves for your cooking. ![]() In Conclusion – Black Spots On Basil Leavesīasil is one of those must-grow herbs.Are Black Spots On Basil Leaves Safe To Eat?.How To Treat Black Spots On Basil Leaves.Black Spots On Basil Leaves Caused By Fungus.What Causes Black Spots On Basil Leaves?. ![]()
