How to protect your potting shed

Every gardener worth their salt knows that the potting shed should be the safest place in the world. Whether your shed’s an oasis from the stresses of life or somewhere to cultivate precious seedlings, it needs full protection. The last thing you want to warp or crack is the roof over your head, and that’s the part of the roof most exposed to the elements. Read on to find out how to protect your potting shed. There should be two things on your wood preservative to-do list:

  1. Biocidal protection with Roxil Coloured Wood Preserver
  2. Moisture protection with Roxil Wood Protection Cream

Protect your garden shed from water to protect it against all types of wood deformation. 


  • Kinking 
  • Crooking
  • Cupping
  • Bowing
  • Twisting

If too much moisture seeps into wooden joints, they can warp out of place to cause serious structural defects. Warped panels can expose the shed’s interior. Shield empty pots from mould and algae growth by providing a dry and stable shelter for them. 

Don’t let your potting shed turn into that rickety old neglected thing at the bottom of grandad’s garden. Keep tools rust-free and plants healthy with wood preservatives like the Roxil Combination System.

What is a potting shed?

Potting sheds are wooden buildings that sit in the garden. They can be any size, and usually consist of a small area with a shelf next to a large, weather-facing window. The rest is up to you, although many potting shed owners like to hang hooks and install lower, shaded shelving for plants that need to be hidden away from the sun. Stick a comfy chair in there and you’ve got yourself a refuge from the stresses of everyday living.

Potting sheds can also be used as storage. Securely hide away garden toys, leaf blowers and lawn mowers to deter theft and keep walk-ways clear. Potting Sheds are perfect for enthusiast gardeners and people looking for multi-use buildings.

Potting Shed vs Greenhouses

Greenhouses are allergic to footballs. Potting sheds keep plants safe from child’s play and can stand up to accidental scrapes and knocks.

There’s also insulation to consider. Greenhouses leach heat through big glass panels. In a mild country like the UK, greenhouses are a bad idea for any plant that prefers warmer temperatures.

A potting shed is made of wood, which is naturally a more insulative material. This makes it easier to keep plants warm in cooler months. The more resilient structure of the potting shed also means plants have increased protection over sudden cold snaps or showers.

Experiment with varying levels of shade to keep different plants at different stages of their lifecycle. All plants need sunlight to grow, but not all plants like full exposure. Some plants, like Snowdrop flowers and Bellflowers, require part sun and part shade to thrive. The combination of shelter and exposure makes potting sheds the ideal environment for these types of plant.

But Potting Sheds are more than just gardening space. Unlike greenhouses, potting sheds usually have enough space for tools and equipment too. It’s also a great place for a quiet moment with a cheeky cup of tea and a biscuit.

Garden space is precious, and potting sheds are a great way to economise and cultivate a versatile and adaptable garden space. And unlike glass, the resilience of wood can be improved with the application of wood preservatives.

In your potting shed, only the plants should be green.
