If the plant was just transplanted the same day, it likely needs a little TLC for a few days so that the roots can get established in its new home. Otherwise, wilting is a common sign of stress. In this case, put the plant in part shade for a while. Gradually expose it to more and more sunlight as the days pass. (If it is not able to be moved, provide some shade over it, such as with shade cloth found in garden centers.) Keep up with the watering, but don’t overdo—basil doesn’t like soggy soil. After this treatment, it should recover fine.
That being said, keep an eye on it once it is in full sun. If it starts to turn brown at the edges, it may be due to sunscald, which can happen during a heat wave. During times of extreme heat, provide some shade and be sure to keep up with watering. Brown edges and curling may also mean pests or diseases are attacking the plant—check for insects along the stem and under leaves. Too much water, too little sunlight, too much fertilizer can also bring on the same symptoms. Keep soil evenly moist, and allow plenty of sunshine once established, but provide shade during high heat. Hope this helps!
