CHECK FOR BLACKFLY

Blackfly can affect a wide range of plants in spring and summer, from beans to dahlias. The pests suck the sap from the plant which weakens it affecting growth and flower or vegetable formation.

Check your plants for these pesky insects, which are around 2mm in size and are mainly black. They often assemble on younger shoots and leaves.

Blackfly and other aphids are at their worst after rainfall when the temperature rises and humidity increases. They are often joined by ants who feed off of the sugary secretion left by the aphids and protect them from predators.

Blackfly are sometimes naturally controlled by ladybirds and certain types of larvae however you can help your plants by removing and squashing smaller infestations or using an organic pest control spray on your vegetable plants.
