Everything You Need To Know To Grow Sunflowers From Seed To Harvest

Published 2024-07-20
Sunflowers are iconic. There are many varieties that you can grow in your own garden, and those of you in zones 9 and 10 can even grow them all year long. Let's talk about everything you need to know from seed to harvest!

They're some of the easiest flowers to grow, but they have a ton of benefits as well. Before you start, though, think about WHY you're growing the plants. If you want to grow them to eat, you're going to want a different variety than if you want to make floral arrangements.

GROWING

Sunflowers LOVE sun. They should be in a full sun location and do better during the warm season, but they can be grown from February through November successfully.

They're large seeds and need moisture to germinate and break the shell, but can be direct sown pretty easily.

MAINTENANCE

Sunflowers really don't need a whole ton of effort. Just keep them watered! For most gardeners, you probably don't need to do much else, and they can even survive in areas where other plants might not do as well. If you want to give them a boost, you can add some fertilizer.

HARVEST

If you want to save the seeds, you want to allow the plant to fully develop the seeds. When you can brush your hand across the front and get the excess material off, it's ready to get cut and dried. Choose a shady location with low humidity and good airflow.

  • I love sunflowers and I say that as a first-time sunflower grower this year. My Mammoth’s are already nearly my gutter in height and were grown initially for solar protection/solar cooling. Now, I am planting them all over and have many different varieties popping up here in the PNW. I will be taking what I learned this year and apply it to my strategy for next year 👊🏻🌻👊🏻

    MY MOM & DAD ARE FROM GARDEN CITY, KS. When we were kids visiting my uncles farms, the highway & roads were walled with sunflowers & in between were deer eating. Childhood memories ❤️🌻

    I'm loving my silverleaf sunflowers, in 9b CA, second year of growing them. I discovered them on the "crime pays but botany doesn't" channel, a Texas native growing wild on a rocky poor native Texas soil. They're drought resistant, they have blue gray fuzzy leaves, goldfinches go crazy for the flowers. Flowers are recursive (most flower nodes branch a new stem) and therefore you get a billion flowers at the end if the season. I can't say enough about the Texas silverleaf sunflowers. Also the rufous hummingbirds enjoy these sunflowers' nectar. A single tiny seed grows into a 5 to 7 ft tall multi-branch shrub, I grow patches of ~ six plants, and they forma protecting thicket that has the aura of a community, a microclimate, A place of its own, like a redwood grove is a place of its own. They also make a nice living hedge protecting my windows from a view of the street.
  • I’m growing Pro Cuts on a 3 weeks succession. Started off with the White Nites and Orange. Now getting ready to plant out Horizon. I always start them inside under lights because the birds are notorious for eating the newly germinated sprouts and it is easier to keep them moist when they’re germinating. I plant them in blocks 6 inches apart to keep the stems smaller for vases and cut them when the first petal starts to lift so the pollinators don’t get to them and shorten their vase life. I might try some branching ones next to enjoy them in the garden.

    Great, informative video! I love how you mention the variety of uses and the benefits to the ecosystem! I can tell you're doing worthwhile work!❤
  • I LOVE grey stripe mammoth Grow them every year and many more volunteer. Have an 8 footer this year coming close to blooming which somehow found it's way into my long raised bed so it's towering about 12 feet right now with the elevation of the bed. They are just magnificent and against the blue sky they are absolutely beautiful. They are one of several plants that I always let grow where they landed last year as the birds feasted. THANK YOU for the info on the seeds. I've kept those we consume in glass jars after a long dry out but will most definitely be saving the grow seeds in paper bags from now on and so will be able to get those stored sooner.

    I have many volunteer sunflowers, and I have transplant a few to other areas, I love chocolate cherry and I usually leave them for birds ❤I have seen so many bees 🐝 and bumblebees it’s beautiful
  • I planted only one Evening Sun sunflower and one Tithonia in my raised beds as opposed to planting them in the native soil like I did last year and WOW what difference in the size of these plants. The Evening Sun is towering over the whole garden at 12' tall and just stated blooming. The Tithonia is a massive 6 foot bush shaped like a Chistmas tree but no blooms as of yet, can't wait though because the Monarchs seem to really love Tithonias. 🌻Zone 9B Coastal California🌻
  • I like growing native plants to support the vanishing California native ecosystem so I plant native sunflowers 🌻
  • @ct2136
    Rabbits are eating my sunflower seedlings, but the adult dwarf sunflowers are looking great in the parkway. Dwarfs really bush out
  • @bobobaggins95
    Tried growing some big ones the last few years. The bed I've grown them in was crap, the first year they only got to about 40cm tall, then the second year they got to almost a meter. This year and still currently those beds have popped off and are full of flowers, so this spring and summer im anticipating they get even bigger 🤞 I just want some mammoth ones, I wanna experience a giant sunflower in my garden haha, and the bees go absolutely nuts on them even when they arent as big
  • @lucylu530
    When I gardeners in California, the finches always ate my sunflower leaves. Here in Idaho, the finches don't eat them. Weird! I noticed, in Washington, they don't eat the leaves either..
