Pulling down to correct level

I too will join the fray.

I planted my first mature Veltheimia capensis bulbs with half of the bulb
exposed when I lived in a very hot climate with summer temps over 100F for
three months.  By the end of the summer you couldn't see any of the bulbs.
How?  I don't know, but I don't think the physics is against it.  If you
tried to punch through asphalt with a shoot of a plant you couldn't do it,
but plants frequently are able to do this amazing feat.  Taking a bulb and
pushing it into soil is very different from a bulb pulling itself deeper.  I
am sure there's someone who knows all about the physics of hydrostatic
pressure, which has something to do with this.
