Every year my cardoon gets infested with black fly and every year I spot one or two ladybirds and hoverfly on there so I do nothing, expecting a massacre any second, which never comes and I just have to deal with the massacred looking cardoon.
Any ideas on how to encourage the Predator bugs or ideas why they might be so rubbish? Do try to keep the garden stocked with pollinator friendly stuff etc
