How To Stop Mould In Garden Sheds

Garden sheds are often the unsung heroes of our outdoor spaces, providing much-needed storage and a sanctuary for both tools and gardening enthusiasts alike. However, every shed can become breeding grounds for mould if not properly cared for.

In this blog post, I will guide you through understanding what causes mould in garden sheds and share invaluable tips on how to prevent it so that your shed remains fresh, clean, and functional all year round. Read on to learn how you can keep your beloved workspace free from dampness, rot, and other unwanted nuisances!

Understanding Mould In Garden Sheds

Mould in garden sheds is a common problem caused by factors such as poor ventilation, high humidity levels and damp items being stored inside.

Causes Of Mould Growth In Sheds

As a gardener, it’s vital to be aware of the various factors that can lead to mould growth in our beloved garden sheds. Keeping an eye on these causes helps us take preventive measures and maintain a healthy, mould-free shed environment:

1. Excess Humidity: High levels of moisture inside the shed are one of the primary reasons for mould growth. This can occur due to damp weather, poor ventilation or storing wet items.

2. Condensation: Insufficient insulation and temperature fluctuations can cause condensation within the shed, promoting mould and mildew formation.

3. Inadequate Ventilation: A lack of proper airflow in your garden shed prevents moisture from evaporating, creating a breeding ground for mould.

4. Leaks and Water Ingress: Any water entering your shed through damaged roof materials, windows or doors can encourage mould growth by increasing the interior dampness.

5. Poor Shed Maintenance: Neglecting regular cleaning and maintenance tasks may result in moisture build-up and subsequent mould formation.

6. Storing Damp Items: Placing wet or damp items like gardening tools or clothing inside your shed only adds more moisture to the environment, increasing the likelihood of mould growth.

7. Incorrect Storage Practices: Not leaving enough space between stored items or against walls restricts air circulation, allowing humidity levels to rise within your shed (which can also leads to mice entering).

8. Untreated Timber: Many sheds come with untreated timber that is susceptible to absorbing moisture from its surroundings; this can escalate the chances of mould formation if not treated with appropriate protective products promptly.

By being mindful of these common causes for mould growth in garden sheds, we’re better prepared to prevent them from becoming problematic and damaging our valuable gardening equipment, supplies and cherished plants.
