Specific pests

Aphids , Leaf-mining sawflies

Specific diseases

Powdery mildew

General care


Cut back stems after flowering. Cut down leaves in autumn or earlier if affected by fungal diseases.


Sowing from seed is the preferred propagation method. Aquilegia hybridises freely in the garden so plants grown from garden-collected seed may not come true to type. Divide and replant roots in spring. Resents disturbance so may take some time to recover

About this section

Our plants are under greater threat than ever before. There is increasing movement of plants and other material traded from an increasing variety of sources. This increases the chances of exotic pests arriving with imported goods and travellers, as well as by natural means. Shoot is working with Defra to help members to do their part in preventing the introduction and spread of invasive risks.
