Best Food for Roses

Banana peels have all the balanced nutrition needed for a rose plant.  You can add the peel to the top of the soil, tucked under much or cut it up in bits to mix in with mulch.  As it curls up and turns black, it will decompose and release all the nutrients the rose will need.  The minimum is one per month but mine get more than that.  It will reduce insect and disease issues while increasing bloom.  You won't need purchased rose food.  The peel is all you need and it won't attract vermin as long as it is just the peel and not the banana too.
