$2 million is lost every week in the Australian landscape tree industry – caused by root deficiencies. We think that there can be, and needs to be a substantial improvement. Ten years of trials and development work have led to a proposed new pot and procedures to help to cut this appalling loss rate. Losses and causes are discussed in IPPS paper as published
Since 2002, we have tested our 1.5 and 8 litre RocketPots by direct sowing about 8,000 seedlings, mostly eucalypts, We dissected several hundred root balls, The consistency of the results impressed us - as reported in the IPPS paper.
There is an urgent need for new pots and procedures. Our ultimate goal is OctaPot C - a compostable pot that can be planted with the seedling – It will be made from recycled paper and can with a clear conscience!
OctaPot C will lead to seedlings that can be planted out very early in their development. Perhaps as early as the first true leaf stage.
The new 0.26 litre pot will allow laterals to grow uninhibited and unpruned through the 6 mm holes in the guidance cusps into its new environment – (if the radical is pruned as soon as it reaches full pot depth).
Shelf life will be extended because a month can elapse before the root ball is fully colonised. Taper will be enhanced.
An example of the success of uninhibited seedling growth is shown by Kings Park. Perth 2012 trials Corymbia calophylla seeds were sown direct to 45 litre 3DARP pots. 8 months later the seedlings were planted with 25+ mm calliper and 2+ metres tall in Kings Park streets. We have replicated these trials in Berwick this year.
Regrettably, this feature will be sacrificed if there are project delays, but there will still be a first quality seeding when fully colonised.
