Primula leaf spot

Time to act:

Jun, Jul, Aug

Spores carried by water and wind spread this fungus, which leaves primula foliage peppered with holes. The initial signs are spots in a yellow-orange area, or in grey, papery tissue. When the centre falls out, holes appear. Look beneath the leaves and there may also be white fungal growth.

Symptoms

Spots on the leaves, fringed yellow-orange, possibly with white fungal growth beneath. Some spots might be white, others brown, surrounded by papery tissue. When the centres fall out, the leaf ends up peppered with holes.
