I've got the runt of the street obviously, I'm new here, it's noticeably smaller and has less buds than the others.
Just wishful thinking then?
I'm no horticulturist and just remember being told that tomato roots are split into two types and each is better at taking up either water or nutrients. So totally irrelevant really.
Edit: I can see plenty of big roots which grow almost horizontally under the turf, some are very big in proportion to the tree, which is what got me thinking along the different roots for different uptakes line.
