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
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?
