This is a question from my father iin law who lives in Teruel, Spain.
He's been growing tomatoes for the past 10 years or so and he tells me he has a plague of 1cm worms which are all over the soil and leaves of his tomatoes & cucumbers.
He grows outdoors undercover in large 25ltr plastic pots filled with a mixture of manure and soil (isn't that to much?)
Each year, he changes 1/2 the containers contents with new soil/manure but never changes the whole lot.
I have told him that he should change the whole lot and wash out the containers if he is using them time and time again..but,. he never listens to me.
Has he paid the price for this?
And what can be done?
This maybe one for Italophile
