When it comes to building cold frames, it is important to choose the right type of wood that is resistant to rot. This is because cold frames are typically placed directly on the ground, and the wood comes into contact with the soil, moisture, and other elements that can cause decay over time.
One of the most popular choices for rot-resistant wood is cedar. Cedar wood has natural oils that act as a preservative, making it highly resistant to rot, decay, and insect damage. It is also lightweight, which makes it easier to work with when constructing the cold frame. Cedar has a beautiful natural color and grain pattern, adding aesthetic appeal to the structure.
Another option is cypress wood, which is known for its natural resistance to decay and insect infestation. Like cedar, cypress contains natural oils that act as a protective barrier against moisture and pests. Cypress wood has a light yellow to reddish-brown color, and it can be left untreated or stained to enhance its natural beauty.
Redwood is another popular choice for cold frames due to its natural resistance to decay and insect damage. It contains tannins and oils that provide protection against rot and pests. Redwood has a distinct reddish-brown color that deepens over time, giving the cold frame a warm and rustic appearance.
Personally, I have used both cedar and redwood for building cold frames in my own garden. I have found that both types of wood have held up well over time, even when exposed to the elements. The natural resistance to rot and decay has saved me from having to replace the entire frame, as I only need to replace the waste strips along the bottom when they begin to decay.
When choosing wood for cold frames, it is important to select rot-resistant options such as cedar, cypress, or redwood. These woods contain natural oils and compounds that protect against decay and insect damage. By using these types of wood, you can ensure that your cold frame will last for many years, with only minimal maintenance required.
