Lean-to Greenhouses: A Guide for Northern Gardeners
What is a Lean-to Greenhouse?
A lean-to greenhouse is a type of greenhouse that is attached to an existing building, usually a house. It uses one of the walls of the building as one of its own walls, which saves space and materials. Lean-to greenhouses are popular in northern climates because they can extend the growing season by providing a controlled environment for plants.
Benefits of a Lean-to Greenhouse
There are many benefits to having a lean-to greenhouse, including:
- Extended growing season: Lean-to greenhouses can help you start seeds earlier in the spring and keep plants growing later into the fall. This is especially beneficial in northern climates where the growing season is shorter.
- Controlled environment: Lean-to greenhouses allow you to control the temperature, humidity, and light levels, which can help you grow a wider variety of plants.
- Space-saving: Lean-to greenhouses are a great way to add growing space to your home without taking up too much room in your yard.
- Attached to existing structure: Lean-to greenhouses are attached to an existing building, which can provide support and stability.
How to Build a Lean-to Greenhouse
Building a lean-to greenhouse is a relatively simple project that can be completed in a few days. Here are the basic steps:
- Choose a location: The best location for a lean-to greenhouse is on the south or east side of your house. This will give your plants the most sunlight.
