It’s perfect weather for those bonkers Autumn mushrooms to poke their way out of the damp, warm soil. On the whole they’re just Fun Guys, but a few are portends of slightly sinister things happening in your garden that probably need your attention.
This month I’m looking out for Honey Fungus (Armillaria).
Signs you may have it:
- A cluster of lovely golden mushrooms with a “collar” on their “necks” appearing in Autumn, usually at or near the base of a tree or stump
- A layer of white between the bark and the soft stem underneath
- “Bootlaces” in the surrounding soil that look a bit like strands of liquorice. Yip, that’s the fungus spreading across your garden [Insert sinister music]
- “Come to think of it, several shrubs/trees died mysteriously in that area over the last few years…”
Good to know:
- Honey Fungus is brilliant at returning the nutrients in dead wood to the soil and is a really important part of the natural cycle.
- Not all species feed on live plants, but several do. And they tend to target all the plants we adore: Cherries, Rhododendrons, Beech, Privet, Birch, Holly, Magnolias, Acers etc etc.
- If someone offers you a ‘chemical solution’ using a fungicide, dubiously licensed as a patio cleaner, don’t. Just don’t.
What to do:
- Stop it spreading further by having recently-dead trees professionally removed and the stumps ground out – this removes the food source that allows the hyphae to spread
- Keep your plants in the surrounding area happy and healthy – they’ll be less susceptible
- Change your planting design (and mindset) to incorporate plants that are less vulnerable. The list is not long, but there are some fantastic plants you may not have considered before.
