Choose a climbing pergola
When choosing a trellis for a modular metal raised garden bed, you should consider the type of vegetables you wish to grow. A light-weight A trellis is fine for pole beans and watermelons, but may not support the weight of squash or melon vines. If you know you'll be growing a variety of vertical vegetables on a trellis, choose a sturdy structure.
Type A climbing pergola
A trellis is sturdy, easy to DIY, and provides space underneath where you can grow shade-tolerant vegetables like spinach or watercress. To use an A-frame trellis in a modular metal raised garden bed, set it up in spring before planting or seedlings. At the end of the growing season, remove these temporary trellises and store them for the winter.
Arched climbing pergola
Vaulted trellis or garden bed tunnels are whimsical but functional structures. These sturdy trellises are perfect for growing pole beans, cucumbers and other grape vegetables. You can also purchase arch trellis for temporary vertical support.
garden arch
Garden arches add a whimsical touch to a metal raised garden bed. They are usually made from wire mesh panels or cow panels and are attached to the ends of metal raised garden beds.
rope trellis
A string climbing trellis is a wooden or metal trellis with a string or string running through hooks. The lattice provides strength and the rope supports climbing crops. You can also use hooks to hang garden nets instead of twine. This is a permanent structure that lasts for many years. That said, twine or rope won't last as long as a wooden frame, and it's best to replace it every spring.
When and How to Add Lattice Frames
The best time to add climbing pergola and modular metal raised garden beds is before planting. If you wait until the plant is actively growing, it can be difficult to do so, and you may damage the leaves or roots of the plant. Therefore, it is better to install temporary and permanent trellis before planting. When building a permanent modular metal raised garden bed with trellis, consider light. If you place a trellis on the south side of the garden bed, the trellis and growing crops will block light from the other vegetables in the garden bed. Instead, place a trellis on the north side of the garden bed so that it runs from east to west. Therefore, set up a temporary trellis at the northern end of the garden bed to avoid blocking the light from the rest of the garden bed.
The frame of a metal raised garden bed has no short-term structure attached; crops are removed and stored once harvested. When placing a temporary trellis on a raised garden bed, be sure to push the supports down into the soil to hold the structure in place. You don't want it to blow over and crush or damage the plant.

Grow your best vegetables in modular metal raised garden beds with trellis!
Various vegetables, such as pole beans, peas, and cucumbers, can be grown vertically, using tendrils or by wrapping them around supports to climb up the trellis. Others, such as indeterminate tomatoes, are not natural climbers and tie the plant to a trellis throughout the growing season. When choosing a vegetable variety for a raised metal garden bed with trellis, be sure to read the instructions carefully. They should be vines, not shrub varieties, to ensure they can climb the trellis.
