My Thai Basil isn't really growing. It's planted in my garden in the herb section, where genovese basil, red rubin basil, parsley, cilantro, rosemary and others are growing at least a little bit (the cilantro is on steroids). Does Thai Basil need a lot of fertilizer or something I'm not aware of? Or is it a slow grower? It is probably receiving too much water since it has been raining a lot.
