I didn't so much as water it when I was done more like give it a bath
100g sugar water hopefully will help it on its' way as it leafs out.Ready for some serious work over the coming years...

You might want to reduce it keeping the the top most branch (stragglers included) in each direction. I tend to like three main branches for a broom but other numbers (e.g. 5) are workable as well. When you've done that you'd obviously need to manage (prune) the strong branches and let the weaker ones build up strength. |

Finally got around to slip-potting this guy into a grow box I knocked up. I realised last year this needs to be fairly beefy to stop the tree tipping over in high winds. Still wasn't big enough in retrospect! Attachment: IMG_4389.1.jpg The root mass was basically just solid, there was some loose particles, but it was way more solid than I anticipated. I'll need a pruning saw to reduce it next time! No coke cans handy so used something else for comparison... Attachment: IMG_4390.1.jpg

Good stuff - the much larger pot will give you room to allow the root mas to expand and drive the growth needed for developing the primary branches. Did you tease the root ball in any way? Be careful with this not to over water it as at the moment there's no roots to absorb water in the outer areas and so those areas will stay wet and in turn keep the the inner area wetter than usual which can deprive it of air. Do you have any pruning plans? I would remove anything that you don't need and beyond that keep the branches that are already big enough in check and let the ones that need beefing up grow freely. |

Ah yes - good point on the over-watering. The base is covered in plastic gutter guard stapled to the inside frame, so I'm hoping that will help there as well as air-prune the base. As for pruning plans, none really tbh! I like your suggestion of the broom, I definitely do need to hard prune the 2-3 large branches this year. Its a bit more protected outside my kitchen door now, so I'm going to spend some time "contemplating it" and see if I can see a specific design that works best for the broom. The only plan I do have is to wire down that lowest branch right on the soil line. I'm expecting to need to approach graft lots of cuttings I take from the tree to build a large nebari, but this one seems to be in a good place to become a root. So I'll grow that out and bury it to try and get it to ground layer. |

OK. BTW branches don't become roots - the sap flow is in the wrong direction. If you remove some bark at the base it might root from there, but if you bury it, it could root, but only to support foliage growing off that branch. So you'd either have a ground level raft or if you romoved the foliage the branch would die. |

Hmm.... very happy to be corrected, but I'd respectfully disagree - I don't buy the "fixed sap-flow direction" hypothesis. I don't see any difference from an approach graft once I've got roots on the "other end". I'd suggest this is just a matter of physics - water flows in the direction of transpiration due to water gradient potential, and a root is just a branch who's cells have differentiated into a different type of cell. Willow cuttings are an excellent example that you can plant them either way up! |

At the moment water will be flowing "up" the branch through the xylem and down the branch through the phloem. Presumably when roots grow from your planted branch you're suggesting at some point in time the sap will suddenly change direction or if it's in the middle of the "branch/root" presumably flow in two opposite directions to provide water to both the main tree and the foliage at the branch end. An approach graft is always done to match and support the existing flow, not against it. Well if you get your theory to work I think you might be the first, unless someone knows better. |

So an update a few years on, and I'm now in big trouble..... My house was undergoing major renovation works, and so I had to move out and leave almost all my trees to their best own devices, for over a year. I sadly lost the single truck air-layer sometime last year thanks to my neighbours cats, but the twin truck was left in that airpot and left in a sheltered spot in the garden.... I was able to get just enough access to it keep it trimmed last year, but this year I had no access to it until about 6 weeks ago, and these are the results today (12th October) It has grown completely through the pot, gone mad and is now huge! 2L bottle of Pepsi for comparison.... It is still completely green all over and not dropped any leaves yet compared to plenty of other deciduous trees around it. The problem I now face is major garden renovation is next on the list, starting next month sometime, and that Acer needs to be moved and "potted", I've no idea into what now! Had I realised how much it had grown through the pot I would have severed the roots January this year around the pot to encourage roots further back. However, now I am too late. This guy needs to be moved and potted and I'm not sure the best strategy to deal with this. Any thoughts much appreciated. |
