Sunflowers are happy to grow on their own and have been cultivated for thousands of years. They are known as one of the three sisters of agricultural companion crops.

This means that three crops are grown together to help each other. The sunflower grows tall and strong to support a climbing bean plant, whilst squashes benefit from growing on the ground and use the shade the sunflower provides so’s not to get scorched by the sun. In turn the squashes shade the soil they all grow in that helps to retain moisture. This is a a great example of companion planting.

I’ve found, throughout the years, companion planting with sunflowers isn’t a precise way of gardening. Nonetheless, depending on your own growing conditions it’s a thrill to find out what you can and can’t grow.

What is Companion Planting.

Although companion planting has been used in agriculture for thousands of years, it has been doing just that in the wild for many melinea before we started cultivating crops.

In extreme climates such as the desserts, different species of plants are found together as the shade of one plant is ideal for another. In the high snow capped mountains, or the arctic, different plants huddle together to protect each other from harsh winds and frosts.

With the help of its companion plant or flower, nature finds a way to survive.

Now, in the modern world, it’s common place to companion plant.  In our gardens it’s the same – but on a smaller scale. Still, growing different vegetables, flowers and plants in the same area with each other is beneficial for many reasons.

Disadvantage of Not Companion Planting With Sunflowers

So, let’s see what’s not to like about companion planting.

  • Most plants have an inbuilt sense to take over as much space as they can. They can push other plants out of the way and grow over them. They can shade their family members from getting the sun and stunting other plants too.
  • Long tendrilled plants, such as ivy’s and vines are so fast growing and can wrap themselves around other plants to the point that they strangle the life out of them.
  • These long tendrilled vine plants are more often than not fast growing weeds that have been given room to grow.
  • A large quantity of the same weeds give pests the right environment to breed.
  • More pesticides and chemicals are needed as pests are more abundant and the good bugs cant cope with the deluge.
  • The need to fertilise soil and put back nutrients by rotating crops has to be done before the next growing season as  one variety of plant sucks all the nourishment out of the ground and gives no goodness back.

Companion planting with sunflowers is something I naturally go towards, I don’t think twice about it. Having said that, it’s fine to grow sunflowers, or indeed any plants on their own too.

1. Lettuces.

These plants relish being in the shade of sunflowers. It helps with not scorching their delicate leaves. They can spread out with floppy leaves or grow compact light and crispy. If you find a little more space between you lettuces, you might want to pop some radishes in there too.

2. Squashes, Courgettes, Zucchinis.

These fast growing plants have a bountiful supply of crop throughout the growing season.. Sometimes the flowers are hidden behind their giant leaves. Luckily The sunflowers bring in many pollinators to share with the squash plants and they soon find the flowers amongst leaves.

3. Onions

Onions are great at keeping certain pests away. Their smell also might deter rabbits and squirrels coming too close and munching on your other plants

4. Spring Onions

As with onions, spring onions can be a ‘keep out’ sign for unfriendly bugs and feasting wild life. I also found that spring onions mature fast and with staggered planting I could have a plentiful supply throughout the summer.  

5. Kale

Kale is another cool loving vegetable. Its love of the shade is a welcomed respite from the sunflowers canopy. Kale grows fast and is a very easy plant to grow from seeds, put the seeds straight into the ground where you want to grow them.

The next 5 salad and vegetables on my list are ones that benefit from the support sunflowers plants can give them. But if your climate is prone to high winds or heavy downpours of rain, and you find your sunflowers drooping or floppy, then additional support may be required, you can find that here

Cucumbers are vine plants and need a little support to lift their fruits off the ground. Depending on how big those fruits are, you might need to help your sunflower support them. Hopefully they help each other.

tomatoes – an ideal companion for sunflowers

Growing tomatoes next to my sunflowers has been a lovely experience to me. I try out 2 or 3 different varieties every year. From sweet tasting Cherry sized ones to great big beef ones. The reds of them look striking against the yellow of my sunflowers.

8. Peppers

Peppers, like tomatoes, are an up right plant that needs sunlight, but not to the extreme of being scorched. The dappled shade and support they require from the sunflowers allow the right amount of companionship they need.

9. Peas

As peas start to grow their soft  twisting and winding tendrils need gentle encouragement to find their way upwards. I check my pea plants daily for this reason, and I must admit, when no one, but my sunflowers are  looking, I’m guilty off popping the pods open and feasting on the young, sweet peas sshhh…dont tell anyone!

10. Beans

Beans are great to grow along side sunflowers. Beans bring beneficial bugs and they will  also share the support you give sunflowers. they give an abundant amount of crops from only a few plants.

Basil is one of my favorite herbs. It thrives well under my sunflowers. It not only enhances the flavors of its tomato and pepper companion plant, basil is an ingredient for many of a tomato, pepper, and garlic sauce for pasta or roasted tomato, pepper and basil soups.  

5. Rosemary

This herb is strong and beautifully scented. Over the years, as the rosemary plant matures it becomes bush like. Pruned yearly and left in situ at the base of where you want to grow your sunflowers, it can be a plant that other companion plants can get support from. Sprinkle

What NOT to Plant with Sunflowers.

Potatoes!

As you can see from the ‘list’ above, there are very few plants I don’t companion with sunflowers.

The one I keep in its own area with its own companion plants are potatoes. Their fast growing tubular roots can disrupt and loosen other plants and flowers they grow near.

If conditions aren’t right, potatoes can be prone to potato blight. The stems can decay spreading to the leaves and then to the potatoes themselves. It becomes hard to stop the rot and disease from spreading to other plants.

But… there are …

Plants That Deter Bees and Other Pollinators.

I also avoid the following plants to companion with sunflowers. They won’t harm sunflowers but they will cause bees, butterflies and other pollinators to visit less. They basically have unattractive aromas or have no flowers.

  • Carnivorous plants.
  • Wormwood.
  • Eucalyptus.
  • Spearmint.
  • Citronella.
  • Evergreen Shrubs.
  • Mosses.
  • Ferns.

Don’t Be Afraid to Mix It Up, I do.

I have tried many companion plants with my sunflowers (Apart from potatoes). They increase the amount of pollinators that visit, and they keep the soil healthy and in need of little attention for the following year.

My Conclusion.

Companion planting is a gardeners delight. The different varieties and species of plants that can grow together is a joy to experiment with.

Using areas in between other plants is a space saver and when in full bloom are glorious to look at. The support of mixed hight planting and the way they look after each other is a delight.

Less weeds, more good bugs, the plants look after themselves, higher crop yield, healthier soil and fewer or no chemicals needed. There’s everything to love about companion planting with sunflowers.
