Jupiter (March 9- July 10) we need to think bigger in order to get where we want to be.
Pluto (April 22-October 2) Pluto retrograde touches us all differently, mostly hidden things come to surface, heal old wounds and some type of death and rebirth cycle will take place.
Saturn (April 18-September 6) look back in the past and make steps forward which life want for yourself.
Neptune (June 18- November 25) new ideas or understanding around our spirituality
Mars (June 26-August 27) review the direction of our lives
Mercury (July 26th-August 19) time to go within and uncover buried thoughts, feelings, and emotions
Uranus (August 7- January 6, 2019) final lessons or gifts, and we will be really encouraged to start a new chapter and a new cycle.
So all in all these retrogrades help us close our past, review our life till now, and make our future - close the old and open a new chapter in your life how you want it - the old way dies, a new will born.
