look at this beautiful sunflower but there’s a dark secret surrounding these Beauties in today’s episode I’ll show you why you might consider not planting sunflowers near other vegetables in your garden you’re in the garden with Patrick before we cover some of the negatives about sunflowers I wanted to cover some basic facts about sunflowers because I’m really not a hater okay um so sunflowers are an annual plant that are native to North America sunflowers are usually known for their large vibrant flower heads which can grow up to 30 cmers or 12 Ines in diameter and that’s not really all some of these sunflowers can reach up to like 10 feet tall the largest is I think 30 feet tall and did you know that sunflowers are just not a flower it’s a flower head that has thousands of tiny little flowers called fettes and those are what the Flor s develop into the seeds so a single um sunflower like this can produce hundreds of seeds one of the coolest things about sunflowers is their heliotropism that means that a young sunflower head follows the movement of the Sun from east to west throughout the day the daily dance helps them maximize photosynthesis but did you also know that when they’re mature the sunflowers usually stop tracking the Sun and they’re permanently facing facing the East so this helps attract the pollinators like bees and butterflies in the morning when they’re most active sunflowers have a rich history and cultural significance in Native Americans uh they first cultivated the sunflowers as early back as 3,000 BC and they’re used for food oil and dye and then in the 16th century the Spanish explorers brought sunflowers to Europe where they quickly became very popular as you can tell so sunflowers are not just pretty to look at they’re also incredibly useful the sunflower seeds are very popular snack and it’s a good source of oil that can be used in cooking and also cosmetics in fact sunflower oil is one of the healthiest vegetable oils available it’s rich in vitamin E and low ands saturated fat one of the issues with sunflowers and perhaps the most interesting is what I found out firsthand in my garden is the tendency to repress the growth of other plants so I want you to take a look at my garlic it wasn’t really ready to be harvested yet for about another month but this sunflower seed uh sprouted and it looked kind of nice and I thought it was going to be beautiful but it killed my garlic it killed my garlic and everything within three feet of the plant this is because sunflowers are allopathic and that means that they extrude a toxin that stops nearby plants from growing well most plants are affected at least somewhat but pole beans and potatoes are especially susceptible and obviously my garlic too be careful when you plant sunflowers around anything in your vegetable garden well if you enjoyed this video and you found something uh helpful please hit that thumbs up and don’t forget to subscribe and hit that icon Bell icon so you’ll get more videos like this and drop a comment below if you’ve had some issues with sunflowers like I have or uh you have some sunflower stories that you like to share thanks for watching until next time happy gardening

Good info, Patrick! I have mine near my raised garden beds but they’re on the ground. That shouldn’t affect my veggie plants right? It didn’t last year. I do have nasturtiums, dill, and marigolds growing near/around it and they seem fine for now. Good to know about it being by the garlic though!!!
Maybe sunflowers are toxic to some plants and not others? What about three sisters gardening that uses sunflowers instead of corn? My sunflowers and tomatoes are growing together right now. Admittedly, the sunflowers are only 8 inches tall. We'll see what happens very soon.
I learned a lot from this video. Thanks for the information. That may explain why my potatoes didn't grow when planted under sunflowers!
I compost everything. I might now assume composting the roots and maybe any part of the plant may be a bad idea. Personally, I don't grow them but I pick up discards in my neighborhood and sunflowers, both wild and domesticated, are very popular.
