From our perspective as climbing plants, a trellis is not a decorative afterthought; it is an essential partner in our quest for sunlight. We are not equipped to grow sturdy, self-supporting trunks. Instead, we have evolved specialized tendrils that reach out, searching for something to grasp. Without a suitable structure, we are forced to sprawl along the ground, competing with weeds and becoming vulnerable to pests and diseases. A well-designed trellis provides the framework we need to climb efficiently, positioning our leaves for optimal photosynthesis and our spectacular flowers for successful pollination.
Our tendrils are sensitive and precise. They require a surface they can easily twist around and cling to. The best trellises for us offer a textured or slightly rough surface, such as untreated wood, bamboo, or a metal grid with a powder-coated finish. These materials provide excellent grip for our delicate tendrils to wrap around and secure themselves. Smooth, thick plastic or overly wide, slick metal poles are challenging for us to grasp firmly. If you choose a material with a smooth surface, consider attaching a network of garden twine or wire to create a more climbable grid for our searching tendrils.
We are vigorous growers and can become quite dense. A trellis must be strong enough to support our weight, especially when we are wet with rain, but it must also provide adequate airflow. Good air circulation through our foliage is critical for preventing fungal diseases like powdery mildew. An open, lattice-style design is far superior to a solid wall. It allows breezes to pass through, keeping our leaves dry and healthy. Please ensure the trellis is anchored securely, as a mature vine, heavy with foliage and fruit, can exert significant force, particularly in strong winds.
You can assist us in the beginning by gently tying our main stems to the base of the trellis with soft plant ties. However, please avoid forcing us or wrapping us too tightly. Our tendrils will naturally seek out and latch onto the structure. Once attached, we will guide ourselves upward. Regularly check our growth and gently weave new shoots through the openings of the trellis to encourage even coverage. This helps prevent us from becoming top-heavy or growing in a single, tangled mass, which can make us unstable and prone to breaking.
Think of the trellis as our permanent home. When designing or choosing one, consider how you will access us for pruning. We benefit from annual pruning to encourage new flowering wood and control our size. A trellis that can be easily accessed from all sides, or one that is not permanently affixed to a wall, makes this vital maintenance much simpler. This ensures we remain healthy, productive, and a beautiful feature in your garden for many years to come.
