How do I treat scale on my maidenhair fern?

Hi Ted,

cut the fern back to 1cm above soil level and spray or squash any remaining scale you can see. Fertilise with half-strength soluble Aquasol Soluble Plant Food or Thrive and apply some seaweed tonic, the fern will bounce back in no time. keep an eye out for any reinfestation and squash them if they appear.
