How to fertilize container grown apple trees?
Hi guys, First of all Happy New Year to you all I have bought myself a family apple tree from Thompson and Morgan and it doesn't really give any clear instruction on how to fertilize the tree. The tree comes with 3 varieties grafted onto it so they will pollinate each other. I did read on the RHS website that fruit trees need a rose fertilizer each spring as it is high in potassium. However there are lots of other websites with conflicting views saying that they just need a balanced fertilizer like blood fish and bone. So could someone please tell me which fertilizer is best for a container grown fruit tree? Thanks
