Are these hosta truly nematode free or is the nematode
population just too low to be detected. I hope the former but suspect the
latter. Just as there is variation in insect population, weather, disease, etc
from year to year, I'd think that nematode numbers vary yearly. Eradication of
nematodes (the bad ones) surely would be utopia but is suppression closer
I would think that places where the ground freezes would be
equivalent to leaving pots above ground.
Is the important factor the lowest temperature, length of time
below freezing (or some other temp), how early in the year the temp drops, or
some combination or an entirely different reason? Are there
any scientists or plantsmen that know the answers?

The pots in
winter..in zone 4 I have buried in sand and wood chips.
At the time I did
not know about the no water and let mother nature take care of them. Haven't
lost any, but I really didn't have any valuable ones at that time.
have found that leaving pots of hostas, that have nematodes, above ground with
no mulch....if they survive, end up with no sings of nematodes the next year.
I now have two plants I have done this to. Kim also had some plants that she
left out over the winter...and they who survived are nematode free.
might be on to something here. If you don't have a way to heat the plants..or
the chemicals to rid them of this pest.
I like the chances of letting them
freeze. I think the survival rate is about the same.
Anybody else find
this to be true?
