When Matthew heard this story he told her that firstly vine weevils and
their grubs are not active now so she wouldn't have seen them and secondly
that we spend over £1k per year on nematodes which we use against vine
weevil. If only she'd asked.......

We have been using Provado for some years in all our containers which
has been reasonably successful, but as part of our effort to rely a bit
less on chemicals I was thinking of trying Nemasys. Do you apply the
nematodes once or twice a year and what is/are the optimum month(s) to
apply it from your experience?
