The message m
from VX contains these words:

I've got two quite small plants that arrived in 3" pots that will both
eventually grow several feet high and I need to know what potting-up
strategy
woud be right. They a

1} Jasminium Polyanthum, currently 15" high and throwing out new shoots and
looking like it will really take off soon, my guess is that it could go
straight into a 10' pot now, maybe bigger still- and

2] A 10" Acer Palmatum Atropurpureum- apparently this thin twiggy little
thing is two years old already. This one is alive, but not doing
anything at
present, but has many buds. My guess would be this needs a middling-sized
pot, say 6' or so and should be repotted up into progressively bigger pots
until it is two or three feet high when I could- maybe- put it in its final
pot (or the ground).

Any ideas- am I guessing anywhere near right with these?

My understanding is that it is better to pot on in smaller stages. I
don't totally understand the principle but the drainage is better if the
roots occupy a fair proportion of the compost.
The jump between sizes can, however, depend upon the vigour of the plant
as if a plant is indestructible and developing very rapidly you can risk
a bigger jump so that you're not having to repot every month or so. But
at this time of year roots are unlikely to be developing very quickly
and the risks of rotting from poor drainage are greater in the cold and
wet. So I wouldn't rush to pot on into much bigger pots, particularly
with the Acer.
