Use a cold frame


Install a cold frame on the south-facing end of the dome to trap heat and provide a more stable microclimate for your plants. The cold frame will help to extend the growing season.

Installing a cold frame on the south-facing end of your dome-shaped greenhouse is an excellent way to trap heat and create a more stable microclimate for your plants.

By doing so, you can significantly extend the growing season and provide your plants with the ideal conditions for growth.

The cold frame works by using a transparent roof and walls made of a material with low thermal conductivity, such as double-glazed glass or plastic.

This design allows sunlight to enter the cold frame and heat up the inside environment, while the thermal mass of the dome absorbs and retains the heat throughout the day.

As the temperature inside the cold frame rises, it creates a more stable and warmer microclimate for your plants, which can be up to 4°C warmer than the outside environment.

The extended growing season provided by the cold frame allows you to grow a wider variety of plants, including those that require warmer temperatures to thrive.

This can include vegetables like tomatoes, peppers, and cucumbers, as well as flowers and herbs.

The stable microclimate created by the cold frame can help to reduce the risk of pests and diseases, as many pests and diseases are more prevalent in cold and damp conditions.

To install a cold frame on the south-facing end of your dome-shaped greenhouse, you will need to build a wooden or plastic frame, and then attach the transparent roof and walls.

You can also add a ventilation system to regulate the temperature and humidity inside the cold frame, ensuring that your plants receive the perfect amount of heat and moisture for optimal growth.

With the help of a cold frame, you can enjoy a longer and more productive growing season, no matter the time of year or your location.

Add insulation


Use a thick layer of mulch (straw or wood chips) around the base of the dome to insulate the soil and keep it from freezing. This will help to keep the roots of your plants warm during the winter months.

Insulating your geodesic dome garden with a thick layer of mulch is an essential step to protect your plants from harsh winter weather.

By surrounding the base of the dome with straw or wood chips, you can create a barrier that prevents the soil from freezing, thus keeping the roots of your plants warm and healthy.

This is especially important for plants that are sensitive to cold temperatures, such as citrus trees, berry bushes, and vegetables like broccoli and cauliflower.

When using mulch, it’s essential to ensure that the layer is thick enough to provide adequate insulation.

Aim for a depth of at least 4-6 inches (10-15 cm) of mulch around the base of the dome.

This will help to keep the soil at a consistent temperature, even in the coldest of winter months.

You can mix in some compost or well-rotted manure into the mulch to provide additional nutrients for your plants.

By incorporating insulation into your geodesic dome garden design, you can enjoy a longer growing season and protect your plants from extreme temperatures.

This will give you the flexibility to grow a wider variety of crops, including those that are typically challenging to grow in cold climates.

With proper insulation, you can extend the growing season and enjoy a more productive and sustainable garden.

Use a hoop house


A hoop house is a temporary greenhouse made from plastic pipes and fittings. It provides additional protection for your plants during the colder months, and can be removed or disassembled during the warmer months.
