Pictured on the left is a root without the benefit of air-root-pruning. On the right, a root that has
been air-root-pruned in the RootMaker®II container. (is a tree seed)
Air pots still have a nervy edge to many RIU growers...claiming mostly they dry out too quick
so not used much in Ca Nv or even any desert conditions
These guys tho use the Air pruning of the pots to actually increase root yield by air pruning the Tap Root
allowing the other roots attached to the tap root to flourish out horizontally
creating a close bushy 'root system' see below:
This 6-inch caliper bur oak was grown with the Whitcomb System® and is 6 years old
Notice root branching in all directions. After 3 months in the RootMaker® propagation container,
and 2.5 years of constriction-pruning in the knit fabric container, this oak was transplanted
and grown for 3 years with the fabric removed.
The only mechanical root cutting was by a 52" tree spade at harvest.
I'm not advocating that members should part with their hard earned cash...
but a test on air pruning the tap root of a spare seedling is no bother
and could prove beneficial as they say bigger roots equal bigger plant = bigger ...
