Where to store organic soil?

I recently just bought a huge sack of Biobizz All-Mix and I dont need all of it right now.

Its an organic soil full of nutrients and active components so where, how and how long should I store it?

I noticed that I kept a bag of my old soil in my garden for a long period of time and after that it was full of tiny worms, and I dont want that to happen again.

Thanks in advance

a trash can with lid

I'd store it as one would Super Soil.
Put it in a large plastic trashcan, keep it moist & warm.

i would dig a hole and bury it under the ground.

I leave my dirt outside in a 55 gallon drum.

A rubbermaid tote, a trashcan, a paint bucket, etc...... Any plastic receptacle with a lid.
