Last autumn I covered my garden in a bark chippings mulch, for frost protection, now I expect it will have take all the nitrogen out of the soil, will a 7- 7 - 7 provide enough nitrogen for general flower beds or will it need something stronger?

You can add sulphate of ammonia, dried blood etc but I would simply use a balanced fertiliser. I think that wold be just fine.

Hi Lyn, while sawdust and similar woody matter does take nitrogen from the soil as it composts down, the good news is that bark chippings take many years to rot, so they won't have taken much nitrogen out of your soil in such a short space of time. 

I think a general balanced fertiliser like that will be just fine.

Thank you both very much for the quick answers.
