Hello ,I’m Marne’ from SW London /Aussie born . I have two trees in total -my Triple trunk Ace Palmatum Japanese Maple 21yrs .Mr Myargi is now 47 yrs old and in previous post -presently investigating dead wood dieback . My Mulberry tree I have had 3/4 years of which I’m looking to try a different fertiliser as to encourage fruit growth . Just not sure about ratio . the Worm liquid & bio gold are a regular for both trees though I have Cal Fog & Potassium. Appreciate your experience & advice re making the change/introduction as to not over fertilising ?

If I may ask some advice please . would it be a mistake in long run to leave dead wood ? Trunk looks to be effected vertically -grown branches on one side though possibly dead wood other side . New soil repotting 1yr ago . Concern is will Ieaving it as & not cutting down further to green wood -risk the possibility of side branches also dying .? Draw an idea of apex of trunks either side at moment with an element of some flow. Appreciate any thoughts .Many thanks
