Flower Power Plant Food?

I saw this plant food recently on QVC - just what I need to pep up the pots and hanging baskets.

A bit of googling and found some 'own brand' high potash plant food with exactly the same ingredients:

This is £7.14 per 800g - the flower power is £10.67 per 800g.

A couple of boxes are on their way.

Also purchased their 'own brand' high nitrogen plant food for the cherry laurels.

 

It pays to do a bit of research!
