Trellis gardening is a method of growing plants using a framework, often made of wood or metal, to support climbing plants. This technique allows plants like cucumbers, peas, and tomatoes to grow vertically, saving space and improving air circulation. It also makes harvesting easier and can enhance sunlight exposure for the plants. Using a trellis can help prevent diseases by keeping plants off the ground, reducing the risk of rot and pest infestations. Additionally, trellises can add visual interest to a garden, creating a more organized and aesthetically pleasing environment.
