Prepare the ingredients: Wash all produce thoroughly. Cut up the cucumber, celery, and apple into smaller pieces so they are easier to mix.
Add ingredients to blender: Put spinach, kale, cucumber, celery, apple, lemon juice, and ginger into a high-speed blender.
Blend until smooth: Process on high until everything is properly mixed and the juice is smooth. If the texture is too thick for your liking, add water to achieve the desired consistency.
Strain (optional): If desired, strain the mixture through a fine mesh sieve or nut milk bag for a smoother juice without the pulp.
Serve and enjoy: Serve in glasses and consume immediately for maximum nutrition.
