4. There is an apparent size scaling factor at work. I find that specimens|
in a 6 inch (15 cm) top diameter terra cotta pot will do much better than
in an 8 inch (20 cm) terra cotta pot.
5. Roots from the plants seem to prefer to cling to the container sides and
bore their way down and out the bottom, as though they sense that
conditions for growth (and their work) are better near areas where exchange
of gases and whatnot is greatest. One caveat here is that these plants
reproduce by runners, so the root habit may be an artifact of that
6. At least some minor water circulation around pottings seems to also add
to plant well being, as if there is a transport issue with the water
envelope around the pot as well as phenomena within the container.
Unfortunately, the science here is not easy to establish, especially for a
non-professional grower with only a few plants. So we rely on intuition,
close observation and experimentation to come up with practices that work.
This is not to say that the science does not exist, of course. But the
science is complex. As a substitute we have the lore and practice of
dedicated folks. I maintain that this body of knowledge is actually science
even if purists won't admit to it. You have to go with whatever you have at
