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.
