Breaking flowers allows you not only to get to the iced water drops but also allows you to get to the grass underneath. As we know now, grass is where the points are.
Make matches in between flowers in L and T shapes so you open more than one, at the same time, make as many as you can next to the buckets. Even if you fill the board with water, if you get more than 5 in a row, it will take it all away leaving new crops to fall and hopefully match.
Once the crops land on the grass, you should get the points you need.
