Root pruning - try to keep the larger roots
I just repotted my meyer lemon tree and took the opportunity to do some root trimming while I had it out. It came out of gritty mix and went back into a new batch of gritty mix. I got the old mix out pretty easily and looked at the root structure. Of course there were roots of varying size - my thought was to trim off most of the smaller diameter roots and keep the larger ones.
Is that a correct assumption? All of the other threads I've been reading tonight suggest cutting off the bottom 1/4 or 1/3 of the root ball. But since the gritty mix came out so easy I didn't really have a ball to work with.
