Pergolas, arbors, and trellises look mighty boring without a plant wrapped around their nooks and crannies. But why should you bother finding a trellis plant to cover your garden structure? It might be to provide privacy, add a decorative element, or save space in a small area. And if you’ve run out of room on the ground, you can utilize walls, pergolas, and arbors as a support to grow vining food vertically.
A Cautionary Tale Of Climbing Vines
Careful, though. Not all vining plants are ideal for every garden space. Educate yourself on the best species for your area. While quick-growing vines seem like an attractive option now, a vigorous plant can quickly become troublesome and invasive.
I know from experience. When we moved into our home nearly five years ago, we noticed the previous owners had planted a wonderful vining plant to add extra privacy to the yard area. The vine has quickly grown out of hand, and we’re currently fighting it every summer as it attempts to creep into our garden beds and up our home’s brick wall.
A Sturdy Support
Before adding a trellis plant to your garden, be sure to check that the support itself is sturdy enough to hold a plant. This is especially important if you plan to grow vegetables vertically. Will your arbor or trellis be able to support the weight of mature squash or cucumber? Your structure should be properly mounted or installed so that it doesn’t wobble or waver.

An early crop for many gardeners, peas like cool weather and enjoy a supportive structure as they grow. Without support, peas sprawl onto the ground and are more susceptible to picking up disease.

Peas prefer slightly acidic soil and should be watered sparingly. You can grow them with success in zones 2 to 9.
