Why do we throw a hail of tiny white rice grains at the newly married couple as they make their way from the ceremony? 

The answer is three-fold. Rice or Grains symbolise fertility and are a symbol of prosperity 💫 The wish was for the couple to have a family, and if your fields had a lot of grain growing in them, you were prosperous.

What Is the Rice Toss? 🌾
The rice toss is a symbolic wish to the just-married couple for a life of prosperity and fruitfulness, which to the ancients meant many children. 
As a blessing, guests shower the couple with rice as they exit the ceremony.

When does the rice toss take place?

There are two times in the wedding day that a throw or toss might happen: 
1. Recessing from the ceremony down the aisle by the couple or 
2. the grand exit as they leave the reception. 

At modern weddings, the rice throw is usually done following the ceremony and not generally used for the grand exit after the reception 🫶🏼
