Fungicides and Peony

[Livingoffroyalities]

My well established peony seems to have developed black spots over its leaves and stems and although it bloomed some of the buds didn't open up and looked 'burnt'. Researching I have concluded this seems to be some sort of fungal infection. Pretty much the whole plant was infected, so I have cut it back and disposed of the cuttings.

I am now not sure if I should I now put down a fungicide? If yes, when should I do this? Also, is there a pet/child friendly fungicide they all seem pretty toxic?

TIA

They are all toxic!
(You could argue that something like a garlic drench would work and is non toxic)

If you've already cut it back I'd just leave it and hope for a better spring 2025! The incessant damp caused so many fungal problems. Just make sure you pick up all the bits.

Fungicides (generalisation) are far safer than insecticides as we have less in common with fungi compared to insects.

I'd opt for something sulphur-based. Sulphur is absolutely as safe as you can get, is an excellent fungicide, and is safe for pollinators etc. Basically once it's been sprayed, it's safe on stuff, just try not to spray it AT bees etc.

It also works very well on spider mites etc if you have those :)

@TheSpottedZebra I agree, I think the unseasonably wet weather has caused this issue. Might sprinkle some sodium bicarbonate down as a natural fungicide, as it can’t hurt. I will also have a look at sulphur ones as recommended by @C1N1C although I need to be very careful due to child and dog.
