Should sunflowers be deadheaded? As a general rule, deadhead flowers when they start to fade, or when they are damaged and no longer attractive, but do so before they produce seeds. When a sunflower's flower head stops looking as vibrant as it once did or when its yellow ray petals have fallen off, select it for deadheading.
Do sunflowers need a lot of water? They thrive in hot weather with full, all-day sunlight, but they require 34 inches of water annually for best growth. Some of that water comes from rain and natural water in the soil, but most is dependent on regular watering. Do sunflowers bloom more than once? Sunflowers grown as annuals die after producing their flower heads go to seed. They do not grow and bloom again.
Sunflowers grown from seed sown directly in the garden will have well-established roots and stronger stems and be less likely to fall. To further encourage proper root growth, provide well-draining, organically-rich soil, and plenty of space between plants. These annual plants boast giant flowers, sometimes measuring more than a foot across.
They make a good screen or backdrop and attract all sorts of pollinators. Some varieties have edible seeds. Most need staking to prevent them from falling over in the wind or rain.

Many dwarf types are branching and offer multiple blooms per plant. Some are double-flowered, some are bicolored, and some are pollenless.
Dwarf sunflowers are the perfect size for cutting and using in arrangements. Helianthus annuus 'Teddy Bear'. Height: 2 to 6 feet tall Bloom size: 4 to 8 inches across. Known for their fuzzy, fluffy, or soft texture, double sunflowers are attention grabbers. Available in semi-double or fully-double forms, their flowers last longer than single-bloom varieties and make excellent cut flowers. Many are pollenless or have minimal pollen. Zones: Height: 1 to 10 feet tall Bloom size: 2 to 5 inches across.
Perennial sunflowers will come back year-after-year. They are tough plants that offer weeks of flowers. Rather than sending up a giant flower head, like many of the annual types, these sunflowers form clumps with many smaller flowers.

We garden in a very windy spot. This article says to avoid winy places for growing sunflowers, which is the one part of which I disagree. Sunflowers love the wind! Thanks to the wind, our sunflowers grow massive and impressive looking trunks like trees. A very few get knocked over when the soil is wet, and a hard wind comes through, but they just make up for it and grow stronger with a bend at the base.
By the end of summer, the thick stems tower overhead like the canopy of a magnificent flower forest. We took a road trip and after passing the mountains surounding the capital we found ourselves driving through miles and miles of sunflowers.
I asked a Turkish friend about them when we got back into town and was told that they harvested the heads for seeds and oil and the white pulp in the stems they used to fabricate Insulation. Some have told me to cut the seed head off my monsters when birds start eating them. It's cold here and I didn't have alot of room in the house so I put them in paper bags cut in pieces each and put them in the shed.
The backs have turned black on some and some of the seeds have mold on them. Can they still be harvested and eaten? Do I need to bring them in where it's warmer or is it too late? We would not advise eating the moldy seeds. Unfortunately, if the others were kept in the same bag, they may have mold spores on them despite looking alright.
Planted six seeds this spring. Five survived and now are from eight to ten feet tall. One of them has a head about ten inches in diameter and drooping over. What, if anything do I do with it? My first time for Sunflowers. What do I do with them this fall? We have been stationed in Germany for almost a year. I decided to buy some bags of sunflower seeds for the birds and one of the seeds germinated in my flower bed.
I left it alone to see if it would grow. It is now approximately 4 feet tall. The interesting thing is that it is one stalk with 3 flower heads on it. Is this a normal thing?
One head is now opened, second is half opened and 3rd is just starting to open. I can send a photo if you need to see it. Yes, this is normal! Many sunflower varieties produce more than one flower, while others typically the giant ones only produce one. Planted year old seeds. Plants instead of growing leaves on the main stock new arms with leaves and very small flowers grow.
First time this has happened to me. Plants are six feet tall now, and very bushy, four feet wide. Unless the main stem was somehow damaged…? Sunflowers will branch out if damaged. We got a small package of sunflowers in July to plant. Will they last until next year or should we go ahead and plant them now and try to retrieve some of the seeds for next year?
Sunflower seeds will last until next spring without issue, as long as they are kept in a cool, dry place. Skip to main content. You are here Gardening » Growing Guides. How to Plant, Grow, and Care for Sunflowers. By Catherine Boeckmann. In most regions, this will fall between April and mid-July.
In the south, this will probably occur in mid-March or early April. Sunflowers dislike having their roots disturbed, which is why we recommend direct-sowing instead of transplanting.
Sunflowers grow best in locations with direct sunlight 6 to 8 hours per day ; they require long, hot summers to flower well. Choose a location with well-draining soil. Sunflowers can also heal the land! You have to handle the full sunflowers carefully after and they need to be handled as toxic waste, but the land is safe again after. These sunflowers are so pretty! I have always loved sunflowers and wanted to grow some of my own! Oh, what cool flowers! I bet they are simply gorgeous when in full bloom!
And I love that they are so practical — they provide additional fee for the animals. How cool! They die after they bud out of the ground. These are beautiful though! We have never intentionally grown them. I grow mammoth sunflowers along the fence of my veggie garden every year simply because I love them. My grandmother had a section of the garden that she planted just for herself, a decadent luxury in her opinion but she loved that tiny patch of color.
I carry this tradition on by planting a row of these beautiful sunflowers and I enjoy them all year long. Thanks for sharing this post. My 12 year old would be in heaven! Our soil here is crap. Love them — worth the space they take up. Pollinators love these, too, which is important. You can also use them as structure for beans to climb.
I will definitely pick some up! Maybe I will brave it this year. Very beautiful flowers, I have never really grown sunflowers. Do you think they would grow fine indoors?? My favorite sunflower is a Russian too — peredovik, early and beautiful! Plus seeds are edible. Hello there! I am trying to make almost all of my plants in the garden functional this year. Found out I have a Linden tree in the back as well.
