Adding a trellis is a great way to add visual appeal to your garden. A trellis is a great accent to any garden, adding structure, and degree of privacy to a garden space if used as a wall. They are also perfect for showcasing plants. You can buy trellises at any garden store, but they are actually quite easy to build. The simplest trellis for plants to create is called a ladder trellis. Building ladder trellis for plants is a simple project requiring only modest effort and expense. The materials are readily available and the time required depends on how many ladder trellises you’re building.
