A trellis is a structure made of wood, metal, or plastic that supports climbing plants like vines and flowers. It usually consists of a framework of vertical and horizontal slats, allowing plants to grow upward while receiving sunlight and air. Trellises can be found in gardens, backyards, and even on balconies, adding beauty and organization to outdoor spaces. Using a trellis can help maximize space in small gardens by encouraging vertical growth. This not only makes the garden look more attractive but also helps plants thrive. Additionally, trellises can provide support for vegetables like tomatoes and cucumbers, making them easier to harvest.
