Record mushroom sightings predicted across the UK this autumn by RHS
Overview
The Royal Horticultural Society (RHS) has predicted record sightings of mushrooms and toadstools across UK gardens and green spaces this autumn, following a combination of prolonged hot weather, drought, and subsequent wet conditions that created ideal growing environments for fungi.
Key points
- The RHS expects public inquiries regarding fungi sightings to exceed last year's record numbers.
- Early sightings at RHS Wisley in Surrey include large rooting boletes and giant funnel mushrooms.
- Prolonged hot weather and drought followed by wet autumn conditions provided ideal flourishing environments.
- Following a 2025 drought, garden fungi inquiries increased by 43% compared to the previous year.
- RHS senior plant pathologist Jassy Drakulic noted that fungi indicate a healthy ecosystem by recycling organic matter and supporting plant health.
- Experts recommend mulching with organic matter, keeping dead wood, and leaving autumn leaves to encourage beneficial fungi.
