Green beans, especially pole beans, are known climbers. They love to grow upwards, using anything they can find for support. This natural propensity to climb is why many gardeners provide some form of vertical support for their beans.

Traditionally, a trellis, stakes, or even a simple tepee structure is used. But what if we told you that tomato cages could be a fantastic, resource-saving alternative?

  2. Stability: Tomato cages are sturdy and designed to hold heavy tomato plants laden with fruit. Hence, they can easily handle the relatively lightweight bean plants.
  3. Availability and Cost-effectiveness: If you already grow tomatoes and have extra cages lying around, it’s an opportunity to make the most of what you have without incurring any additional costs.

  2. Planting: Plant your bean seeds around the base of the cage. Ensure to give them enough space for root development. Generally, planting them 3 to 4 inches apart should suffice.
  3. Guidance: As your beans start to grow, gently guide them onto the cage, encouraging them to twine around the wires.
