I'm trying to wrap my head around the general plant physiology concept that leaf surface drives root growth, and root growth drives leaf surface growth. (or maybe that's not even stated accurately.)
The specific situation I have is young seedling trees or even grafted trees under 3 feet tall - the trees are trying to form lateral branches at this short height, branches which are too low to be viable fruiting branches long-term.
So my thought had been to pinch-off this lateral growth to encourage more vertical (apical bud) growth.
So my question is - if the axiom stated at the outset is true, am I hindering the root establishment of these young trees by reducing the photosynthetic potential?
(The assumption/catch here is that by pushing multiple branches, the tree can increase leaf-surface faster than if it is only pushing from the top bud. This may not be true)
Thoughts from the intelligentsia?
