For example, sunflowers should not be planted in the same field more than once every three to four years because of high susceptibility to sclerotinia head rot; the same applies to soybeans because of cyst nematodes. Regular crop rotation also reduces the likelihood of weeds building tolerance to herbicides.

What do farmers do with sunflower stalks?

Sunflowers continue to be an important oilseed crop worldwide. Many of them are used for birdseed but most are processed into vegetable oil. The green stalks are chopped like silage and used as cattle feed.

Can you overseed sunflowers?

What should not be planted near sunflowers?

The allelopathic characteristics of sunflowers are toxic to some plants, potatoes being one of them. This process inhibits germination and can stunt the growth of potatoes. They also compete for nutrients in the soil. Potatoes should be planted well away from sunflowers to avoid them affecting one another.

Can sunflowers grow with other plants?

Some plants grow well together because they thrive in the same type of soil. Numerous bush bean varieties, such as wax, lima and green beans, are good sunflower companions for that reason. All of these plants are well-suited to acidic soil, with a pH level ranging from 6.5 to 7.5.
