Have you considered consulting someone in the Dept of Horticultural
Science at Guelph maybe if Toronto does not have such a Dept.
I dont have many references but a computer search on capillary or
subterraean watering will be likely to give you some leads.
Clemens J. et al. 1991 Watering plants five different ways.
International Plant Propagators Society Proceedings 41:98-102
Costin J J 1988 The capillary bed method of irrigating nursery stock.
ibid 38:335-338
We use this kind of thing down under but it is easier to see it first
hand rather than go into elaborate detail so find some place that is
doing it. These ideas are adaptable to pots or groups of pots that must
go for sometime between waterings.
