How can I get rid of small black flies in my hyacinth pots?
These flies or fungus gnats are often found in compost that has been stored outdoors in wet conditions, or in very wet, poorly-drained compost. You can control this pest for up to 3 months by inserting cardboard 'pins' of Bug Clear Ultra for Pots from Scott's into the compost.
