Hi
just opened up a bag of potting mix which has been in the garage for a couple of months and inside is very compacted and white. Still good to use or time for a new bag?
Hi @KC18,
Welcome to the Bunnings Workshop community, it is fantastic to have you with us.
The white stuff is mycelium, which is like the root system of mushrooms. It's a normal and healthy part of soil structure.
I would simply break up the soil and use it as previously intended.
Let me know if you have any further questions.
Jacob
