Vermiculite mixed with soil

I would like to find out the following: how long does it take vermiculite to maintain its water absorption capacity when mixed with the soil? In other words, when do I know when to remove the old vermiculite in the soil and replace it with new vermiculite? I would really appreciate your help. Thanks and

Regards,
Teboho

Vermiculite can compress after about 2 years of use in soil and lose some of its water holding capacity. Any vermiculite which has been stored in its packaging and has been kept dry should last for years.
