Multipurpose plant food

QuestionsMultipurpose plant food

I planted some flowers in a bed & threw on some multipurpose plant food (grey granules) & after a week the bed was covered in little two-leaf green shoot things. Nicer looking than weeds & very easy to pull up as their roots were just below the surface but I suspect weeds none the less. Could the plant food have set something off in the peat moss to sprout these ‘shoots’?
