We&#39;re sorry to read about your disappointment with Miracle-Gro Moisture Control Potting Mix and appreciate your feedback.<br />Fungal mold spores including mushroom producing fungus are a natural part of soils It just takes the right conditions for the spores to develop into a fungus or mold. Our growing media products are not sterilized and may contain microorganism including fungus. In fact, fungus mold has been scientifically proven to improve the growth of plants by releasing nutrients from the organic material that growing media are typically lacking. The fungus mold only becomes a problem if there is an overgrowth. Overgrowth occurs when the soil mulch is too wet. The mold and fungus that grows on soils and mulch will not harm plants and is safe for people and pets to be around although as always, we recommend you use gloves when handling for soil that has not been used yet allow it to dry out on some newspaper outside before using. For soil that has already been used, allow the plants to dry out a bit between waterings. It will not hurt the plant to allow the soil to dry between waterings but will typically eliminate any mold fungus growth which needs the extra moisture. Keep in mind that mold and fungus on growing media or mulch will go away with sunlight and air circulation.<br />We want you to be confident in our products. For this reason, we offer a product guarantee to our consumers. At your earliest convenience, please reach out to us at 877-220-3089 if we can further assist.
