•
The nonlocal symmetry for the Gardner equation is derived by the truncated Painlevé analysis or the Möbious (conformal) invariant form.
•
To solve the initial value problem related with the nonlocal symmetry, the original Gardner equation is prolonged the enlarged systems.
•
Many explicit interaction solutions among different types of solutions are given by using the symmetry reduction method to the enlarged systems.
