Aphidsby mrgadmin on April 22, 2023

Aphids feed on soft leaves of many species like Birch, Maple, Mayday, Hawthorn and many shrubs. Aphids can reproduce without mating in summer, so populations can rapidly increase.

Aphids cause damage by piercing the soft plant tissue and sucking plant sap.They excrete “honeydew”, which make leaves appear shiny. Sooty mould fungus grows on this honeydew, creating a black scum that can stick to cars, patio furniture, decks and sidewalks located beneath aphid-infested trees.
