Horticultural grit v clay granules

[AntiqueVases]

Hello

Long story short, I got confused between grit and clay granules and repotted my cherry tree with clay granules. (I'd originally potted it with 100% compost which went mouldy)

Do you think my cherry tree will be ok with clay granules?

Do you use clay granules and/or actual grit from stone?

Thanks

Bonsai enthusiasts use clay granules as part of a soil mix, also things like lava rock as they are good at retaining both water and air to improve soil structure.

How long ago did you repot it, and what did you mix the clay granules with?

When you say the previous soil went mouldy, are you sure it wasn't microrrhizal fungi, which is beneficial?

Thanks @Yamadori

It was yellow mould and stinking. As opposed to white cob-webby type mould which I believe might be the good kind.

I repotted yesterday with 1/3 clay granules and the rest B&Q multipurpose compost.

@AntiqueVases Ugh, that yellow stuff doesn't sound right at all. It might be worth spraying the tree with a general purpose fungicide such as Roseclear.

If you are due to get a heavy frost or snow where you are, it might be worth moving it into a frost-free area such as a garage or shed for a short while. It doesn't hurt deciduous trees to be kept in the dark in really bad midwinter weather, as they have no leaves so need no light.
