How close could I plant apple trees (M9) to my rows of gooseberries and black currants?
Apples have a root spread of about 5 feet - I wouldn't put the tree closer than 4 feet - stem to stem. In reality, you'll probably measure from the widest part of the fruit bushes (so that you can move around them) so I don't think this would be an issue.
Hope that helps
Thanks that's very helpful.
