Sunflower Trellis

Sunflowers will brighten any garden, but can they perform double duty as a trellis?

Depending on the size and height of the variety they can, but what can you grow up them?

DIY Sunflower Trellis

When making a sunflower trellis there are certain things you need to pay attention to.

  • Sunflowers have some varying degrees of allelopathy.
  • You need to grow vining crops up them.
  • Shading for the crops due to the large leaves.
  • Sunflowers falling over from the weight of the vining crop.
  • Sunflowers may not be the best support in very windy areas.

How to Use Sunflowers as a Trellis

  • Sow Sunflowers when the weather warms up in the springtime after the risk of frost, this is usually early or late May in our zone.
  • After 1-2 weeks sow your pole beans (make sure they are pole not bush beans!) at the base of the sunflowers. Don’t put them too close as the sunflower roots take up lots of space (your pole beans will find their way don’t worry).
  • Once the pole beans begin shooting out the vine, help the pole beans attach to the sunflower stem if needed.
  • Keep an eye on your sunflowers & beans and be ready to harvest about 2 months later.
  • The more beans you pick the more harvests you get so pick the beans every couple of days.

Have you used sunflowers as a trellis before? Did it work?

  1. Thanks for the info! So happy to have found your blog! I’m fairly new at vegetable gardening and plan to grow sunflowers in front of the north fence of our garden, with snap peas growing up them. I started the sunflowers in 5″ peat pots 4 days ago and plan to direct sow the snap peas this week. The spacing on my snap peas says 2″ and on the sunflowers, 6 – 12″.. How far in front of the row of sunflowers would you recommend sowing the peas?

    • Hi Jes! Welcome 🙂
      I haven’t grown peas up sunflowers because they have ‘tendrils’ that latch to climb, whereas pole beans actually wrap the whole vine up a pole (or sunflower stem) and also ‘lean’ to find something to climb. Peas don’t tend to reach out as far, although you can help them latch. You can definitely try growing peas up sunflowers, but I’m not sure how it will go. I’d space them 4-6 inches away and try and help them attach as they grow. Best of luck!

  2. My pole beans did not do well with sunflowers last year, but the cucumbers did ok. The pickling cukes climbed the sunflower stalks with no problem.
