What should a greenhouse sit on?

When it comes to choosing the right foundation for your greenhouse, there are several options to consider. The most common choices are slabs, concrete, or bare earth. Each option has its own benefits and considerations, so let’s take a closer look at each one.

1. Slabs: Laying your greenhouse on slabs can provide a stable and level surface for your structure. It’s important to ensure that the slabs are laid onto a good level surface to prevent any shifting or sinking over time. Before laying the slabs, it’s a good idea to prepare the ground by removing any vegetation or debris and leveling the area. This will help to create a solid foundation for your greenhouse.

2. Concrete: Another popular option is to place your greenhouse directly on a concrete foundation. This can provide excellent stability and durability for your structure. When pouring a concrete foundation, it’s important to make sure that it is level and well-cured before placing your greenhouse on top. This will help to prevent any cracking or shifting of the concrete over time.

3. Bare earth: If you prefer a more natural approach, you can choose to place your greenhouse directly on bare earth. This option can work well if the ground is already level and stable. However, it’s important to consider the potential for moisture buildup and pests when placing your greenhouse on bare earth. You may need to take extra precautions such as installing a barrier or using gravel or mulch around the perimeter to help prevent these issues.

Personal Experience: In my own gardening and landscaping endeavors, I have used both slabs and concrete foundations for my greenhouses. For smaller structures, I found that slabs worked well and were relatively easy to install. However, for larger and more permanent greenhouses, I opted for a concrete foundation for added stability and longevity.

It’s important to note that the choice of foundation will also depend on factors such as the size and weight of your greenhouse, local climate conditions, and personal preference. If you’re unsure about the best option for your specific situation, it’s always a good idea to consult with a professional or seek advice from experienced gardeners in your area.

To summarize, when deciding what your greenhouse should sit on, consider the options of slabs, concrete, or bare earth. Each option has its own benefits and considerations, so it’s important to choose the one that best suits your needs and circumstances. Ensure that the chosen foundation is level, stable, and well-prepared to provide a solid base for your greenhouse.
