    Just thought I'd share this photo with you guys.
    This is a 1.5ft red dissectum in a garden opposite me....or at least it was.The little red tree is still there...still 1.5ft,but as you can see the owner let the rootstock get 'slightly'out of control.The poor guy has to keep cutting it back now as it's nearly as big as the house.

    That's very surprising : usually when the rootstock overgrows the grafted part, the graft dies.

    It would be interesting to have a look at the base of the tree to see how deep it is planted : if the scion (the graft) was planted with the bottom under soil level, maybe it has developped its own roots, it has self-layered.

    In an old bonsai magazine, there was an article about a bonsai nursery man (bonsaika to make it short) who had his technique for repoducing cultivars difficult to root as cuttings or air-layers.

    He would first graft the scion on a regular stock, then the second or third year, he would air-layer at half distance of the diagonal scar left by the graft. These people have a lot of patience, and passion too, to try such things ;°)

    I agree, except for the cause and effect relationship.

    In my opinion, when the graft is dying, the rootstock overgrows the (dying) grafted part.

    ... because the graft doesn't produce enough auxin to suppress bud release on the rootstock.

    Hi again...I've watched this giant grow,though not closely from it's original size.It isn't planted too deep so you can rule out the dissectum being kept alive in the style of a nurse graft.I agree a lot of cultivated plants die off or at least suffer badly when rootstock takes over.I guess it's natural for trees to get rid of less productive growth so maybe the dissectum is on borrowed time now....or become a successful parasite! I might see if I can get a pic if anyone's intereted though I don't like the idea of being caught snooping ha ha.
    Agree Alain,the bonsai guys have so many tricks up their sleeves.As 'D' mentioned,Heron's bonsai root into sphagnum moss,and when they make the initial chop on a tree they then root the discarded top which is at least 25mm dia...amazing!
