The labels have come off my bags of fertilizer that I keep in the shed.  So it is possible that I may have put potato fertilizer instead of onion fertilizer on the bed I'm going to put the onions in.  I don't know what is in them, but if they are both fertilizers, will they be very different? I'm hoping I will still be able to plant my onions sets as planned. Does anybody know what the differences might be and what I could do to correct the mistake

for example chempac potato fertliser is 6:5:7 + 4 mgo

and their onion fertiliser is............................................... exactly the same

so I really wouldn't worry about it

Phew thanks Mum!

Mix them and you can do both crops... 

As Mum says - they are basically the same so no worries..
