Larch Group re-pot

My Larch group planting has put on a lot of growth last year, so much so that it was slowly lifting itself out of the pot.  As Larches don't like to be root bound, it was time for a re-pot.

The Buds are just turning from brown to green, so just about perfect timing.


Out of the pot and on to the turntable.  If you look closely, you can see the mass of circling roots. 


The roots were teased out gently with a root hook



All the circling roots cut off with a sharp pair of shears


The top layer of moss and the old sail has now been removed to make sure that the new top dressing will still  show the surface roots.


Time to get the tweezers out to remove as much of the dreaded Ragwort as possible


I still haven't found a suitable pot for this group, so it's going back in to the mica pot.  Four tie in wires are more than sufficient for the job, as the root system of the trees in this group has tightly knitted together.
Potting mix is 1 part Akadama, 1 Part Moler Clay, 1 part sharp grit.


The group is now placed in the pot and secured with the tie in wire.  Where the wire crosses major roots, it is covered with plastic tubing to prevent damage to the roots.



More of the potting mix has been added and carefully worked in to the roots to make sure no air pockets remain.  The whole planting is then top dressed with a mix of 2 parts Akadama and 1 part grit.


All done, good for a couple of years.  I hope to find a suitable pot by the time it needs repotting again.
