plants in pots

The way this experiment is reported is misleading, I have tried over
potting with many bulbs, trees and shrubs. As Roland suggests, other
factors come into play. I strongly advise against over potting of most
central Asian and European 'bulbs'. If over potting is tried, then optimum
growth conditions must be given and care taken that there is a lot of air
in the compost. Such lush plants can collapse very easily.

Soft fast grown timber might be very handsome and make good pulp but strong
timber or a tree grown in character is better grown much more slowly.

Of course the roots of plants seek the edges of pots and run around them,
just as they would to anchor themselves in a crack in rocks, The water flow
carrying air and nutrients which roots in soil seek is found best between
surfaces, in this case the surface of the pot and the soil, in the case of
my bulbs in pots -between the under potted bulbs and the particles of grit
in the compost. Juno Iris HATE over potting, Pogons don't seem to mind.

Another factor is  that many bulbous plants grow much better as a clump
rather than as separate bulbs, a fact to remember when considering the
separating of seedlings. I suspect that hormones may have something to do
with this. -the sibling bulbs being mutually supportive. Snowdrops are a
classic example.

I also suggest that it is very sensible of plants to only grow to the size
that their roots can support!
