Subject: Nematode free: Fact or
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 to reality?
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?

pots in winter..in zone 4 I have buried in sand and wood chips.
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
I 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.
We might be on to something here. If
you don't have a way to heat the plants..or the chemicals to rid them of
I like the chances of letting them freeze. I think the
survival rate is about the same.
Anybody else find this to be true?
