 Re: Peach prune!
40mm is too deep by say.....40mm! We are assuming that for all their faults (and if they're like 90% of the nursereies over here there are many faults) the surface level of the pot is correct for the root system inside...therefore you have to plant the root ball once removed from the pot so the level matches the soil surface level you have in your garden site.
What Ozinus was pointing out...correctly..was that by burying the stem like that you (amongst other things negative) stimulate the production of whats called adventitious roots above the primary root system, this is not a good thing and we often see very large trees that have nbeen buried at some latter stage in their lives fail as the primary root system decllines dies and rots away...the adventitious roots keep the canopy/leaves alive and green but provide little or no structural support, the tree is highly prone to windthrow and catastrphic failure.
Now with your little sapling it is never going to grow into a giant tree, nor is it going to threaten your house...however it is better to prevent the numerous problems being buried will create re the ongoing health of the tree and its battle with pressures from pests and pathogens, soil and airbourne.
The pruning you have done I feel is good and will help, you should lift the plant and position it correctly re the root ball and the soil surface, but there's some things I would advise you to check first.....You need to see if in fact there is a great mass of fibrous roots coming from the buried stem out into the soil around it...personally I'd be surprised if there is more than a few, I don't think there is much to be gained by throwing the plant into massive shock by cutting away these roots dramatically in one big hit...so check that first and get back to us. We can then look at the best way
