Similarly, when should Mexican petunias be pruned?
In general, the only pruning a Mexican petunia requires is an annual pruning in late winter or early spring to remove damaged, weak or otherwise undesirable stems back to the base of the plant. Cutting back spent flower stalks during the blooming period helps maintain a neat appearance.
