As temperatures rise this spring, many gardeners are eagerly starting seeds from scratch, but a common problem threatens their success: mould development on young seedlings. Gardening expert and TikTok creator Ish has revealed two straightforward solutions to ensure seeds thrive without fungal issues.
The Mould Problem in Seed Starting
Growing seeds can be incredibly rewarding, yet many gardeners inadvertently create conditions that foster mould or fungus. Ish explains that the ideal environment for seed germination—warm temperatures, humidity, and moist soil—also serves as a perfect breeding ground for mould. This issue is widespread, often leading to seedlings that appear "gross" and fail to flourish.
First Fix: Adjust Watering Practices
The primary mistake gardeners make is overwatering. While seedlings require moist soil to thrive, excessive water transforms the soil into a mould hotspot. Ish advises easing up on watering, adding just enough for the seeds to absorb without saturating the soil. For those uncertain about the right amount, a pre-planting soak can help. Soaking seeds in water a day before potting provides a "kickstart," reducing the need for heavy watering later and minimising moisture-related mould risks.
Second Fix: Improve Airflow in Propagation
Another critical factor is airflow during propagation. Many gardeners cover small pots tightly to retain humidity, but this traps air and creates a stagnant, humid environment conducive to mould growth. Ish emphasises that proper airflow is essential to prevent mould and fungus. He recommends leaving a small gap in any covering, such as a bag, to allow adequate ventilation. This simple adjustment ensures a healthier environment for seedlings to develop without fungal interference.
Combining Solutions for Optimal Results
By implementing both fixes—moderating watering and enhancing airflow—gardeners can significantly reduce mould risks. Ish assures that these changes are easy to apply and can lead to robust, mould-free seedlings. As spring progresses, these tips offer a practical guide for avoiding common pitfalls and achieving successful homegrown plants.
In summary, with careful attention to moisture levels and ventilation, gardeners can enjoy the fulfilment of growing seeds from scratch without the setback of mould. These expert recommendations provide a clear path to thriving seedlings this season.
