This is my multi layered Zelkova {Japanese Grey Bark Elm} that i collected last winter .It had suffered severe die back for numerous years and when dug up was found to be planted in water-logged clay . With only 3 side branches and a very poor excuse for an apex i decided to tripple layer the trunk and this is the progression .The layers were set after the initial leaf burst had hardened off .
The base of the tree is around 90mm and stands around 1600mm high .The layers were set approx' 100mm below the main side branches and will have trunks from 40mm to 65mm when severed .They should make for some impressive informal upright or slanting style brooms .In most cases Zelkova's lend themselves to formal upright or broom style , these will have further layers taken from the apexes of 2 of the starters next sesson to produce a couple of broom style smaller trees.
Again plastic soft drink bottles cut down formed the tubes for the layers and wrapped in duct tape .Watering via a large syringe from the top without opening the layer makes it an easy task .Cheers
