Sunflower how long to bloom

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.

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. They have long tap roots that need to stretch out; in preparing a bed, dig down 2 feet in depth and about 3 feet across.

Sunflowers thrive in slightly acidic to somewhat alkaline soil pH 6. Sunflowers are heavy feeders, so the soil needs to be nutrient-rich with organic matter or composted aged manure. Or, work in a slow release granular fertilizer 8 inches deep into your soil. If possible, plant sunflowers in a spot that is sheltered from strong winds, perhaps along a fence or near a building.

Larger varieties may become top-heavy and a strong wind can be devastating. Before planting, decide whether or not you want to grow a fun sunflower tower. If you wish, you can plant multiple seeds and thin them to the strongest contenders when the plants are six inches tall. Give plants plenty of room, especially for low-growing varieties that will branch out.

Make rows about 30 inches apart. For very small varieties, plant closer together. A light application of fertilizer mixed in at planting time will encourage strong root growth to protect them from blowing over in the wind. Experiment with plantings staggered over 5 to 6 weeks to keep enjoying continuous blooms. If you see birds scratching around for the seeds, spread netting over the planted area until seeds germinate.

Check out this video to learn how to plant sunflowers:. Caring for Sunflowers While the plant is small, water around the root zone, about 3 to 4 inches from the plant. To protect the plant, it may help to put snail or slug bait around the stem. Once the plant is established, water deeply though infrequently to encourage deep rooting. Unless the weather is exceptionally wet or dry, water once a week with several gallons of water.

Feed plants only sparingly; overfertilization can cause stems to break in the fall. Tall species and cultivars require support. Bamboo stakes are a good choice for any plant that has a strong, single stem and needs support for a short period of time. Birds and squirrels will show interest in the seeds. If you plan to use the seeds, deter critters with barrier devices.

As seed heads mature and flowers droop, you can cover each one with white polyspun garden fleece. If you have deer , keep them at bay with a tall wire barrier. Curious deer may bite the heads off of young sunflowers. Sunflowers are relatively insect-free. A small gray moth sometimes lays its eggs in the blossoms. Pick the worms from the plants. Downy mildew , rust , and powdery mildew can also affect the plants.

If fungal diseases are spotted early, spray with a general garden fungicide. Cutting Sunflowers for Bouquets For indoor bouquets, cut the main stem just before its flower bud has a chance to open to encourage side blooms. Cut stems early in the morning. Puffy blisters then appear on the undersides. The disease may spread to stems and flowers causing distorted growth. Rust sometimes spreads to the cultivated sunflowers from weeds such as wild mustard, shepherd's-purse, pigweed, and lamb's-quarters.

If fungal diseases are spotted early, spraying with a general garden fungicide as directed on the product label can protect healthy foliage. Remove and destroy seriously infected plants. Keep the area weeded and clean up plant debris from the garden in the fall. Disinfect tools by dipping them in a solution of 1 part household bleach to 4 parts water. Keep your hands clean, and do not handle plants when they are wet. A small gray sunflower moth sometimes lays its eggs in developing sunflower blossoms.

Its larvae are greenish-yellow with 5 brown stripes down their backs. They feed in the flower and destroy seeds, creating a mass of webbing and debris. Pick the worms from the plants and mash them between your fingers or drop them into a plastic bag for the trash. If lots of plants are infested, spray or dust the flowers with a product containing Bacillus thuringiensis Bt as soon as you see the larvae. The larvae will eat the bacterium and soon die.

Because sunlight and rain rapidly inactivate Bt, respray as directed on the product label. In the early fall, check flower heads for signs of maturity.

The reverse side turns from green to a yellow-brown. Large heads will nod downward. A close look will reveal the tiny petals covering the developing seeds have dried and now fall out easily exposing the tightly packed mature seeds. To harvest the seeds ahead of the birds and squirrels, cut off the seed heads with a foot or so of stem attached and hang them in a warm, dry place that is well-ventilated and protected from rodents and bugs.

Keep the harvested seed heads out of humidity to prevent spoilage from molds and let them cure for several weeks. When the seeds are thoroughly dried dislodge them by rubbing two heads together, or by brushing them with your fingers or a stiff brush.

Allow the seeds to dry for a few more days then store in airtight glass jars in the refrigerator to retain flavor. Sunflower seeds are rich in vitamins, proteins, and minerals, as well as linoleic acid which helps the body metabolize fats properly.

They contain about 24 to 27 percent protein, only slightly less than an equal weight of ground beef. Furthermore, sunflower seeds contain about twice the iron and potassium and about 4 times the phosphorus of beef.

Raw sunflower seeds also contain vitamins B and E, and a dash of vitamin A. Sprouted, they also contain vitamin C. Use the seeds for snacks, alone or mixed with raisins, dried fruit chips, and nuts. Add hulled sunflower seeds to salads and use them in fruit or vegetable recipes. Substitute sunflower seeds for nuts in baking. To toast the seeds to enhance their flavor, lightly brown them in a skillet over medium-low heat for about 10 minutes, or on a cookie sheet in the oven at degrees F for about 10 minutes.

Rather than sending up a giant flower head, like many of the annual types, these sunflowers form clumps with many smaller flowers. Photo courtesy: All-America Selections. Many gardeners are surprised to discover that sunflowers are available in more colors than the classic bright yellow. There are types with deep red flowers, others that show of beautiful combinations of color and still others that are white.

False sunflowers resemble smaller versions of true sunflowers, but have raised, cone-shaped centers. The petals stay with the flower instead of withering and falling off, as sunflowers do.

False sunflowers are perennials and can be easily grown in zones Size: 24 to 32 inches tall, up to 2 feet wide. Are sunflowers poisonous to cats or dogs? You can safely grow them in your garden and use them in arrangements indoors.

Do sunflowers follow the sun? Young sunflowers face east to soak up sunlight in the morning and track the sun as it moves westward throughout the day. This process is called heliotropism. Once sunflowers have reached maturity, they stop following the sun and face east from then on. Are sunflowers weeds? Sunflowers are known for popping up on their own well, actually with the help of birds. For some gardeners they are a treasured surprise, but to others they are a frustrating weed. If you want to harvest sunflower seeds to snack on or to feed the birds with later , plant larger varieties of Helianthus annuus annual sunflower since they have the biggest seeds.

Note: In order for pollen-free Helianthus annuus varieties to form seeds for wildlife, you also need to plant types of sunflowers that produce pollen. Another option is to cut the drying ripe seed heads and hang them upside down on a fence to give birds easier access.
