Growth Stages of Sunflower: How Does It Grow?

Growth Stages of Sunflower, Life Cycle

Have you ever tried growing sunflowers in your garden? When you try to grow sunflower try to observe the sunflower growth stages so that you will aware of how the plant and the flowers grow.

The sunflower has seeds that can be used to plant and make a beautiful garden beside your house. The flowers and sunflowers are beautiful and they are making the surroundings great.

The lifecycle of the sunflower plant is a series of stages where you will see how to plant grow from seed up to its maturity stage. So how does a sunflower grow?

Growth Stages Of Sunflower

Stage 1. Seed

The first growth stages of sunflower are in the form of a seed. In this stage, still, nothing happens no sign of germination or any activity about the plant. The sunflower seed characteristics are very small with pointed tips on both edges, color black with a smooth texture, and no odor or less smell.

The sunflower seed is considered the beginning stage because it is where the plants grow and develop. Also, most plants have seeds and it is where they start their journey.

If you want to grow sunflowers, you can buy high-quality seeds at nurseries or garden centers. You can also get some seeds online at an affordable cost.

Stage 2. Germination

Once you have already finished your garden plot, you can now start sowing sunflower seeds. You can directly sow the seeds in the soil or you can let the soil germinate first on a seed tray and do transplanting after.

It depends upon which one will you try. Once the seeds are already sowed, they will sprout in the next following days. The seed will grow a tiny root.

Usually, the sunflower seeds will germinate in around 5 to 10 days. The sunflower growers need to pick or buy quality seeds to have a high percentage of germination.

That is why try getting or buying seeds at the nursery or garden centers. But it will also depend on what kind of seeds you have.

You also need to apply some strategies to germinate and grow sunflowers. One example of strategy is soaking the sunflower seeds in the water for 12 to 18 hours.

Then put it on a cloth or tissue paper and place it inside a closed zip bag. After a few days, you will see that the seeds are germinating.

Usually, you will see the white root in one to three days. Once the seeds have sprouted you can now plant the germinated seeds in the soil.

Stage 3. Sunflower Seedlings

After the seeds have sprouted, the next sunflower growth stages are the seeds will turn into seedlings. In this stage, the sunflower seeds become young plants.

The tiny seeds produce roots and grow a few tiny leaves. They continue to grow and they become seedlings. The seedlings will increase their height, produce more roots, grow more leaves, and the stem becomes thicker.

Some gardeners sow sunflower seeds in the soil and wait for them to grow and they do transplant them once they have enough size.

You can transplant the seedlings as soon as they already have enough size. Transplanting old sunflower plants is a little bit risky because they might suffer transplant shock.

It is better to transplant young sunflower plants.

After a few weeks, the seedlings will have a great plant structure and they will become more mature in the next following weeks.

Stage 4. Vegetative Growth

A few weeks after the sunflower seeds become seedlings, they will continue to grow and develop more parts. More green leaves will grow on the plant.

In the early stage, a few leaves only grow on the plant. But as the days pass by more leaves grow on the plant. They are becoming bigger and wider because of their leaves.

Also, the roots are becoming longer and spreading wider on the soil. The roots of sunflower are invasive and they will not cause damage to the structures.

Another thing is the stem grows thicker and longer. It can reach a few inches long and some sunflower varieties can reach a few feet.

The sunflower plant needs more water, sunlight, and nutrients during this time. They need it to grow more and to become more ready to produce buds.

At least 6 hours of sunlight is needed by them to make food and an inch of water per week for them to thrive.

Stage 5. Sunflower Growing A Bud

After a few weeks of growing, once the plant gets mature it will start producing buds. If you have lots of sunflower plants you will see a lot of buds in your garden.

The buds of the plant are immature flowers. It doesn’t open yet but as soon as the buds get mature they will turn into flowers.

While the buds are still not yet open, try keeping them protected from possible pests and diseases that may attack them.

It will feel great once those buds are close to opening.

Stage 6. Flowering

Once the bud is already mature and ready, it will open and the plant will flower. The flowers of the sunflower are beautiful.

They are color yellow and some are yellow-orange. They are lovely to see and if you have lots of sunflower plants you can see a lot of flowers.

Some sunflowers are growing so tall and there are also dwarf sunflower varieties that are growing short.

Also, if you grow multiple sunflower head varieties, you will see a lot of flowers in a single plant.

Stage 7. Seed Formation

Once the sunflower gets more mature, the flowers will form seeds. The seeds grow on the flower and they get hard as time goes by.

During the early stage, the seeds are too soft but once they get mature they get harder.

You can use the seeds to grow sunflowers again. You can save those seeds and store them in a safe place.

If you will get more seeds, you can also sell some of them to earn some money.

Seed Harvesting

The sunflower seeds will take some time to gets mature. If you harvest them too early, some of them are too soft and will not germinate.

You need to let the seeds mature before harvesting them.

The sunflower heads will turn brown and drop which will show that the seeds are ready to harvest.

Some animals also eat sunflower seeds and you can feed them.

Stage 8. Sunflower Plant Is Drying

After the growing period, if you are growing annual sunflowers they will dry up but if you are growing perennial sunflowers then the plant will continue to live.

Many growers grow annual sunflowers and at the end of the growing period, those plants started to dry up.

You need to grow sunflowers again in the next growing season. That is the life cycle of a sunflower plant especially if they are annual varieties.

The plants will fall and will mix into the soil. You can just let the dry sunflower plants mix in the soil because it can improve the soil nutrients in the soil.

The Life Cycle Of Sunflower Plant

The growth stages of sunflower start from the seed. The seed will sprout and turn into a seedling. The seedling will continue its journey and will grow more roots, leaves, and thick stems.

Once the sunflower plant matures, it will grow buds. The buds will grow and once it opens it becomes a flower.

The flowers of sunflowers will start growing seeds and you can harvest them once they get mature. Then the plants will start to dry and they are going to fall and mixed in the soil after.
