Feeding fruit trees organically

[sausageman]

I've got a conference pear, stella cherry & victoria plum. All about 6 ft tall and bought within last year. Do I need to be feeding them with anything? Local garden centre suggested potash of sulphate but I want to keep to organic. Nettles any good here? I've got some organic summer fruit fertilser from Growing Success - can I use that? Any advice much appreciated.
Thanks

Hi sausageman and welcome to the site. I`d be more inclined to use a balanced fertilizer such as Fish, Blood and Bonemeal, rather than sulphate of potash anyway.

Here i have some information on organic ferrtilizers.Commonly available organic fertilizers contain: natural materials from rock minerals to seaweed, from traditional fish, blood and bone meals, to composted chicken manure and high humus matter.Add to these a new range of products I call - Biofeeds which recruit microorganisms to improve plant health naturally.
