Gilberto plants a variety of trees, shrubs, and flowers in his yard. The landscaping beautifies the neighborhood. Due to this, a positive external will be generated.

So basically Gilberto's planting is creating positive externality because negative externality is when the third party gets negatively affected by production or consumption. Production or Consumption of something, whether third party is directly or indirectly involved.
