Sunflowers are stunning flowers that always bloom toward the sun and have many positive connotations. As a result, many people choose to cultivate this flower to add beauty to their surroundings. So, how to plant Sunflower seed and care for them? Please read this article on gardenhow.net to find out the answer.
An overview of Sunflowers
Helianthus Annuus is the scientific name for the Sunflower, which belongs to the daisy family. The Sunflower is a North American native. Sunflowers are an annual flowering plant. The blossoms appear in a variety of colors (yellow, red, orange, maroon, and brown), but the most frequent hue is bright yellow with a brown core that matures into a big head full of seeds.Sunflowers are heliotropic, which means that their blossoms turn to follow the sun’s passage across the sky from east to west, and then turn back to face the east at night to prepare for the morning sun. Heliotropism occurs in the early phases of flower development before the blossom becomes dense with seeds.Sunflower is a drought-tolerant plant that is sensitive to cold, so the best time to plant them is in the spring when the weather is mild.
The best types of Sunflower to plant
Sunflowers are among the most beneficial flowers to have in your yard. These annual plants come in a wide range of sizes and hues, with over 70 different types. Some dwarf Sunflower types only reach 50cm (20in) in height, whereas the tallest varieties can reach over 3m (10ft).Before learning how to plant Sunflower seed, let’s admire the 15 most beautiful types of Sunflowers and pick one for your garden.

When is the best time to plant Sunflowers?
One of the most important guides on how to plant Sunflower seed is choosing the right time for planting. To achieve the successful blooming, you should grow your Sunflowers:
- After the threat of spring, frost has passed and the soil temperature has reached at least 60 °F (15.55 °C), sow Sunflower seeds directly into the garden (or outdoor containers).
- This will occur in most areas between April and mid-July. In the south, this will most likely happen in mid-March or early April.
- Sunflowers dislike having their roots disturbed, which is why direct-sowing rather than transplanting is recommended.

How long does it take for Sunflowers to bloom?
Sunflowers are a fairly fast-growing flowers given their size, taking between 80 and 120 days to flower after sowing, depending on the type. You can use this function to determine the best time to plant Sunflower seeds. The tallest Sunflower varieties can reach heights of over 16 feet, while smaller versions are designed for tiny spaces and containers and rarely grow taller than a foot! In the large-seeded types, the flower heads can grow to be over 12 inches in diameter.
Preparing before planting Sunflowers
We’ll start with some basic preparation before learning how to plant Sunflower seeds.
Choose Sunflower seeds
All you have to do now is choose your Sunflower seeds to get started! When looking for seeds, bear in mind that there are three types of Sunflowers: tall, dwarf, and colorful. Tall Sunflower cultivars can reach a height of 15 feet. (The world’s tallest Sunflower stood at 30 feet and 1 inch tall!) Dwarf Sunflower varieties are only approximately 3 feet tall, making them ideal for tiny areas like garden boxes and containers. Thanks to hybridization, Sunflowers now appear in a range of colors.Furthermore, you should get Sunflower seeds from a renowned and trustworthy source to avoid purchasing low-quality seeds with a low germination rate.Avoid seeds that are flat, cracked, or broken, or have termite or pest damage.
Choose a planting Sunflower site
Sunflowers are generally easy to grow, but they do require the proper soil and position.
- Sunflowers are grown from seed and require full light (6 to 8 hours each day) to flower effectively. They require long, hot summers to flower successfully.
- Select an area with good drainage. Sunflowers despise getting their feet wet. In standing water, they develop wide, shallow roots that rot and perish. Choose a location that does not regularly puddle or muck.
- Sunflowers aren’t fussy, but the soil must be loose. They have long taproots that need to spread out, so dig down 2 feet deep and 3 feet wide when preparing a bed.
- When it comes to soil pH, they’re also not picky. Sunflowers grow in soil that is slightly acidic to slightly alkaline (pH 6.0 to 7.5).
- Sunflowers are heavy feeders, so nutrient-rich soil with organic matter or composted (aged) manure is required. Alternatively, work a slow-release granular fertilizer into the soil 8 inches deep.
- Plant Sunflowers where they will be protected from severe winds, such as along a fence or near a building. In a high wind, larger types may become top-heavy, which can be disastrous.
Sunflowers are heavy feeders, according to Renee’s Garden, and benefit from fertilizer toppers upon planting. Fill the top 8 inches of soil at the planting spot with organic or 10-10-10 fertilizer, and feed the Sunflowers again during the growing season.
How to plant Sunflowers
Follow these instructions to plant blooming Sunflowers:
- Step 1: Soak Sunflower seeds for around 8 hours in warm water (3 boiled, 2 cold). Sunflower seeds will be easier to peel and germinate as a result of this.
- Step 2: Fill the nursery pot with soil until the potting mouth is about 2 cm away. You should only foster one seed per pot of soil to make planting easier later.
- Step 3: Gently press the Sunflower seed into the ground approximately 1 – 1.5cm with your hand, keeping the pointed end of the seed facing up, and then cover with a thin layer of soil on top.
- Step 4: Water the soil once a day in the early morning using a spray bottle. It’s important to only water the seeds just enough to keep them from becoming soggy.
- Step 5: Sunflower seeds germinate in around 7 to 10 days. The nursery is then relocated to a cool, sunny place. You should also be watering the soil on a regular basis at this time.
- Step 6: When the roots of the Sunflower tree start to grow and the Sunflower is about 40 cm tall, it’s time to plant it. We can plant Sunflower in a container or in a garden.
- Step 7: When planting Sunflowers, place a tiny wooden stick next to it and connect the flower’s body to it with a string to prevent the tree from breaking or falling.

Secret tips for how to plant Sunflower seed
Following these procedures will ensure that your Sunflower plants thrive once you’ve sown seeds and they’ve begun to grow:
Sunflower seeds require a lot of water to germinate since they contain a lot of natural oil. Water the ground thoroughly after planting. Until germination begins, keep the soil wet with frequent, light watering. Cover your pots with clear plastic wrap to keep moisture in if you’re beginning indoors. As soon as the seeds sprout, remove the plastic.
2. Pruning the seedlings
Thin the Sunflower seedlings to the suggested row spacing for your variety once they have their first set of true leaves. Small Sunflowers may only require 6 inches between plants, but giant types may require up to 3 feet. For garden aesthetics, closer spacing is possible, but congested plants will yield fewer flowers.
3. Put in the sun
Sunflowers require six to eight hours of direct sunlight each day and long, hot summers to thrive.
Mulch your Sunflower plants with three to four inches of mulch to keep soil temperatures above 50 degrees, conserve water, and smother weeds.
5. Create a barrier
Cover the planting spot with broad netting to keep birds, squirrels, and other creatures away from your growing Sunflower seeds. If you live near a deer population, wire fences may be necessary to prevent animals from nibbling on the flower heads.
6. Examine the area for pests and pathogens
Sunflowers have few enemies, but they are vulnerable to moth eggs. Look for these pests in the Sunflower blossoms and remove them if you find them. Sunflowers are susceptible to powdery mildew, downy mildew, and rust, among other diseases. Use a safe fungicide to help keep your plants free of these fungal infections.Also read: Where is the best place to plant Sunflowers?
How to take care of Sunflowers
How to take care of Sunflowers after planting? What are the most important points to remember? Follow this process for super summer Sunflowers.
Sunflower seeds sprout 10 to 14 days after sowing and require a liter of water per week to maintain their growth. Water your Sunflower plant from three to four inches away, near the root zone. To encourage deep root growth, water the Sunflower plant occasionally.
You shouldn’t require any more fertilizing during the growing season if you prepared your soil with compost and/or manure. If you believe your Sunflowers need more nutrition, work a balanced, slow-acting granular fertilizer into the soil around them. Sunflowers, on the other hand, are heavy feeders who are sensitive to fertilization. Nitrogen can help your plants grow bigger, but too much nitrogen can cause Sunflower stalks to snap, especially as the weather cools, so be careful not to over-fertilize. If fertilizer is necessary, keep it away from the plant’s base.
Weed control is one of the most difficult aspects of growing Sunflowers. Sunflowers compete with weeds for moisture and nutrients. To combat weeds, lay down a thick layer of mulch unless you intend to till, hoe, or pull them by hand. Cover your Sunflower garden with a 4-inch layer of organic mulch. To help repel pests and disease, leave an area of bare earth around each Sunflower stalk.
Manage pests and diseases.
Although many pests enjoy Sunflowers, the damage they cause is usually small. In most circumstances, pesticides are not required unless there is significant harm. Because most Sunflowers rely largely on insect pollinators, it’s important to avoid using insecticides during pollination. Sunflower moths, cutworms, weevils, caterpillars, grasshoppers, wireworms, and the Sunflower maggot are some of the pests you may encounter.
The disease is a significant threat, but it primarily impacts agricultural crops. Many illnesses are resistant to new Sunflower cultivars. The only choice after the illness has set in is to remove and destroy the infected plants. It’s possible to have verticillium wilt, sclerotinia rot, rust, and downy mildew. Proper plant spacing in well-draining soil is your best defense.
Birds can be a problem while growing seeds for harvest. Bird deterrents include scarecrows, owl decoys, and shining metal pie plates. You may also keep birds away from your seed Sunflowers by planting oil-rich cultivars like Black Peredovik.
You’ll need to support the stems of some Sunflower varieties because they can grow to be over 16 feet tall. The tall stems of the Sunflower will be staked to support the weight of the budding Sunflower heads. Drive upright stakes into the ground and connect the plant to the stake using plant ties or twine to stake a big Sunflower.
Harvesting after blooming
Cutting Sunflowers for bouquets
- To stimulate side blooms in indoor bouquets, trim the main stem immediately before the flower bud opens.
- Early in the morning, cut the stems. Flower wilting can occur if flowers are harvested in the middle of the day.
- Handle Sunflowers with care. In room temperature water, the blossoms should persist for at least a week.
- To keep Sunflowers fresh, place them in tall containers with sufficient support for their heavy heads, and change the water every day.
Harvesting Sunflower seeds
Harvesting Sunflower seeds is a wonderful way to appreciate the beauty of your garden’s blossoms as well as their fragile seeds. Sunflowers generate a plethora of seeds that can be used in breads, salads, or even made into a creamy nut-free Sunflower butter. You’ll get more edible Sunflower seeds if you grow a seed-producing variety. Seeds should be harvested about 30 days following fertilization.
- Allow the flower to dry on or off the stem until the back of the head has turned brown, the foliage has turned yellow, the petals have faded, and the seeds seem plump and loose.
- Cut the plant’s head off with sharp scissors or pruners (about 6 inches below the flower head). Place loose seeds in a container to capture them.
- Place the Sunflower head on a clean, flat surface and collect the seeds in a basin.
- Simply rub your hand over the seeded region and pluck the seeds from the plant with your hand, or use a fork. Rub the head of the Sunflower across an old washboard or something similar to get rid of it. Simply grab the head and rub it on the board like you’re doing laundry.
- If you’re going to harvest the seeds for roasting, you can protect the blooms from the birds by covering them with a light fabric and securing them with a rubber band.
- Alternatively, you can cut the flower heads early and hang them upside down until the seeds are dry; hang them indoors or in an area where birds and mice won’t get to them.
- Sunflower seeds should be rinsed before being dried for several hours or overnight.
- Refrigerate Sunflower seeds in airtight glass jars to preserve them as fresh as possible. To enhance air circulation, many people keep raw seeds in cloth bags in dark, dry regions.
Questions and Answers
Should I plant Sunflower from seeds or seedlings?

How long do Sunflowers live?
Sunflowers are mostly annuals. They sprout in late spring, blossom in the summer, then die back in the fall with the first frost. When it comes to growing a Sunflower that blooms all summer, the ideal strategy is to plant your Sunflowers every few weeks.
Where is the best place to plant Sunflowers?
Sunflowers flourish in full-sun environments. They are extremely hardy and can thrive in any type of soil as long as it is not wet. They thrive in slightly acidic to slightly alkaline soils (pH 6.0 to 7.5). Sunflowers, once established, can withstand drought, as befits plants whose forefathers thrived in dry prairie environments. They’re so easy to cultivate that they typically start growing on their own beneath a bird feeder.
Sunflower seeds, leaves, and stems exude chemicals that prevent other plants from growing. Potatoes and pole beans should be kept separate. Toxins from the accumulating seed hulls eventually damage the grass below when Sunflower seeds are regularly eaten as bird food. Toxins that are harmless to animals and humans ultimately biodegrade in the soil.Further information: Where is the best place to plant Sunflowers?
Can Sunflowers be transplanted?
You can either transplant a little potted Sunflower into a larger container or a large potted Sunflower into the ground. Sunflowers should be transplanted after the fear of frost has gone, ideally before the first genuine leaves appear.Transplanted Sunflowers should be spaced similarly to direct-sown Sunflowers. The best spacing for rows of tall, large-headed Sunflowers is 3 feet (1 meter), although you can plant them closer together if you choose. You can get away with 1 foot (30 cm) of spacing between small Sunflowers or a few large Sunflowers planted together without any crowding. To reduce transplant shock and settle the dirt around the roots, water it thoroughly after transplanting.Further information: Where is the best place to plant Sunflowers?
When can I plant Sunflowers outside?
Sow Sunflower seeds in 10cm pots of peat-free, multi-purpose compost from April to May. From early June, plant out into the garden once all danger of frost has passed. This could be anywhere from 2 to 4 weeks after your average last frost date, depending on your climate. When the temperature is below 50°F, you can sow, but germination and initial development will be slower.
Sunflowers are a delightful addition to any garden. Their flowers can be cut and eaten as a healthy snack, and their seeds can be gathered and consumed as well.
