Wall-rue, like other ferns, reproduce using spores, which ripen from June to October.

Providing an informal rockery in your garden is great for all kinds of wildlife from toads and newts to spiders and beetles. In turn, these will attract birds and small mammals looking for food. Use larger pieces of stone and rock (acquired from a sustainable source) to create the rockery, leaving space for animals to crawl under. Plant native species like ferns, heathers or herbs to provide food and shelter for minibeasts.
