Choosing the Right Location

Considering sunlight exposure

When choosing a location for your trellis or arbor, it’s important to consider the sunlight exposure. Most climbing plants thrive in full sunlight, so look for a spot in your garden that receives at least six hours of direct sunlight each day. Take note of any nearby trees or buildings that may cast shadows and block the sunlight. By ensuring your trellis or arbor is placed in a sunny location, you will provide the ideal conditions for your climbing plants to flourish.

Assessing wind conditions

In addition to sunlight exposure, it’s crucial to assess the wind conditions in your chosen location. Climbing plants often require some support when it comes to wind resistance, so selecting a sheltered spot will prevent your trellis or arbor from being damaged. Pay attention to the direction of prevailing winds in your area and try to find a spot that is protected from strong gusts. Keep in mind that while some plants can tolerate windy conditions, others may struggle to thrive if constantly exposed to strong winds.

Selecting the Materials


Wood is a popular choice for building trellises and arbors due to its natural beauty and versatility. There are various types of wood that can be used, such as cedar, pine, or redwood. Cedar, in particular, is highly durable and resistant to rot and insect damage. When selecting wood for your project, make sure to choose treated or naturally resistant wood to ensure its longevity. Keep in mind that wood will require regular maintenance, such as staining or sealing, to protect it from the elements and extend its lifespan.


For a more exotic and eco-friendly option, consider using bamboo for your trellis or arbor. Bamboo is a fast-growing and sustainable material that adds a unique and tropical touch to your garden. It is lightweight, flexible, and resistant to pests and rot. However, it’s important to choose the right type of bamboo that is suitable for structural purposes. Look for thick-walled varieties that are more sturdy and less likely to split or break under pressure. Remember to regularly inspect and treat bamboo structures to prevent any potential issues.


If you prefer a modern or contemporary look, metal trellises and arbors are a great option. Metal provides durability and strength, making it suitable for supporting heavy climbing plants. There are different types of metal to choose from, such as wrought iron, steel, or aluminum. Wrought iron adds a touch of elegance and can be intricately designed, while steel and aluminum offer a more minimalist and sleek appearance. When using metal, ensure it is treated or coated to prevent rusting, especially in areas with high levels of moisture.
