One personal devotion is to say the famous St. Joseph prayer as a Novena for nine consecutive days leading up to March 15.
Prayer to St. Joseph (dating from the year 50 AD)
O St. Joseph whose protection is so great, so strong, so prompt before the Throne of God, I place in you all my interests and desires. O St. Joseph do assist me by your powerful intercession and obtain for me from your Divine Son all spiritual blessings through Jesus Christ, Our Lord; so that having engaged here below your Heavenly power I may offer my Thanksgiving and Homage to the most Loving of Fathers. O St. Joseph, I never weary contemplating you and Jesus asleep in your arms. I dare not approach while He reposes near your heart. Press him in my name and kiss His fine Head for me, and ask Him to return the Kiss when I draw my dying breath. St. Joseph, Patron of departing souls, pray for us. Amen.
Joseph was a very good man, and a worthy example of earthly fatherhood.
