Common Questions & Expert Insights

Minimal ongoing maintenance is required. It remains in the soil for years and does not decay quickly, but monitor irrigation to prevent overwatering.)
Q: How should I store it after opening?
Keep it dry and sealed to avoid moisture uptake and clumping. Store in a cool, dry place away from humidity.)
Q: Is it dusty or messy to handle?
Handle with care to minimize dust exposure. Some batches can be dusty, so use appropriate PPE if needed.)
