When the moon is in it's waxing phase... go into your garden a dig a hole (you can use a planter or planter pot also)
Put some money into it, (I suggest 1 dollar bill, and some change) put in a sprinkle of sage.
Close your eyes and imagine money coming to you... then say:
"Take away my poverty, take away my sorrow
Take away my need to beg and borrow"
Add a few seeds of a sweet smelling flower (Or a bulb, such as a hyacinth or Daffodil)....
Now fill the hole with earth and with your finger, draw a pentagram on the soil. Place in a sunny location and wait!
Of course a real money tree won't grow from this... but the spell will attract money to you. As the flower grows so will your income!
