Sunflower plants are a colourful and beautiful addition to any landscape or garden. . Many varieties have something to offer gardeners of all ages, regardless of space restrictions. .. Whether you grow for pleasure, following the best tips for will help provide your sunflowers with the best conditions for good growth and health. Growing sunflowers have been separated from our culture for years, sunflower plays an important role in our culture and in many other cultures. Currently, all these applications are still active, so large corporations and people continue to grow sunflowers.

The natives use sunflowers for decorative and ceremonial purposes, as well as for food and flavourings. The seeds were prepared by grinding them in flour and sometimes they were mixed with beans, squash and corn to prepare a meal. Usually, they squeezed the seeds into oil and divided the grains, and another use of sunflower was to make a purple dye for decoration, face and body paint, and on the fabric. They also produced sunflower seed oil for skin and hair care, and even dried plant stems were used as building materials.

Selection of sunflower species for growing.

The first step to Growing Sunflowers From Seeds is to choose the species you want to grow. There are 67 species of sunflower with one or many stems, with heights of growth, sizes and colours of the heads. Here are the popular species below to help you consciously choose the sunflower you plan to grow.

Music Box is a variety called dwarf, which grows to a maximum height of 28 inches, so it is suitable for container cultivation.

The Teddy Bear sunflower species, smaller than the Music Box, grows to approximately 12-18 inches.

Italian white sunflowers, also a small variety, but with an attractive cream flower.

The autumn mix, unlike the above, generally grows more than 6 feet tall with a yellow and rusty flower head, 5 to 6 inches in diameter.

The largest sunflower species, such as the Russian giant, are more than 15 feet tall and have a large head diameter of up to 20 inches. Of course, larger sunflower species will require more space than other species mentioned above. Very fun if you have space to grow them.

The best location for growing sunflowers.

Sunflowers grow on a soil exposed to direct sunlight and protected from the wind. Protect your sunflowers by supporting the stem with a bamboo stake as soon as the sunflower reaches a height of 1 foot. This will help straighten the stem and prevent the sunflower from damaging the wind. You should also choose a place that protects the plant from strong winds. Sunflowers are generally heavy and can break relatively easily. You can use poles or fences to support so that the plants do not fall during strong winds.

When the sunflower matures, its weight on a tall stem makes it vulnerable to wind damage. Because wild sunflower only grows at a height of 2 to 6 feet, the risk of wind damage is much less than with a homemade sunflower. This variety of sunflower becomes very high, so don’t plant it in a place where they can shade other plants. Sunflowers do very well along a fence or a sunny wall. If you plant them along a fence or wall, you won’t have to worry about protecting other plants, and sunflowers will have support against the wind.

Sunflower Seed Germination Tips

If you prefer to germinate sunflower seeds before planting in the soil, apply at least 10 sheets of absorbent paper towels on a roll and then soak them with water. Sprinkle the seeds evenly with a damp paper towel before placing them in a warm room, such as a ventilation cabinet. The more sheets of paper towel used the better the water retention capacity, which means less frequent watering will be required.

with regular watering will prevent the paper towel from drying out, especially in a warm environment or in direct sunlight. When sunflower seeds begin to germinate, sow compost mixed with manure in your garden at a depth of 2 inches, 1-2 feet apart.

Sowing sunflower seeds in pots

If you germinate sunflower seeds in pots, sow individual seeds in each pot at a depth of 1 inch in 3-inch diameter pots. Before covering the top of the pot with a transparent food film, use good quality pot compost, such as Miracle Grow pot mix.

When the green leaves appear on the ground after germination, remove the sheet and place the pot near the window that, if possible, receives as much sunlight during the day. Turn the pot 180 degrees in the morning and again in the afternoon, checking that the soil is moist.

If the pot was too small or if the sunflower was left in the pot for too long, it is likely that there is a large accumulation of roots around the walls of the pot. Because sunflowers have long-haired roots capable of growing to a depth of 4 feet, allowing the plant to reach this stage in pots will seriously inhibit growth.

Overfilled roots can be safely removed by cutting no more than 1/3 with a sharp knife. Cut and discard dead soil surrounding sunflower roots before planting in the garden. Remember not to damage the remaining healthy roots.


Sunflower seeds are large seeds, so they can and should be planted a little deeper than usual with vegetable and/or herb seeds. Only an inch below the surface. As the name implies, “sun” loves warm temperatures and germinates better in the soil with a temperature of 75 to 80 degrees Fahrenheit (24 to 27 degrees Celsius). The typical germination time is approximately 10 days, although it can be faster under optimal conditions. You can start using sunflowers indoors, but most of the research I have read suggests that they are not transplanted well and better when they start outside.

Soil requirements

Sunflowers thrive better in soil rich in organic materials, especially if you grow a giant type. Being a deeply rooted plant, they are not resistant to sandy soil, since they are easily uprooted by the strong wind. Plant seedlings in good quality soil are the best+ a potting mix with good water retention, enriched with plant foods. Always make sure the soil is wet and do not let it dry completely. Consider adding manure to the soil in the garden where you plan to plant seeds or cuttings.


At an early stage, you should keep the light source as low as possible. If the lighting is too far from the seeds, the stems reach too much light and become fragile and fragile. The amount of light needed each day varies, but 14 to 16 hours a day is a good rule. Soil temperature is crucial, not room temperature, and should be maintained as recommended for seed packages. Most plants work best in the 70-80 degree range, but the preferred temperature will vary. Do your research before starting. Watch your watering again. The soil must be moist and not wet.

When the first planting leaves, known as cotyledons, appear, remove the plastic dome. When your young plants develop their second set of leaves, you can begin to fertilize. Start feeding once a week with liquid fertilizer starting in half. For a good flower formation, you should plant them in an open field with enough sunlight during the day. They can tolerate in shaded areas, however, there should be at least 4-6 hours of sunlight a day.


Sowing Directly in the garden is the most preferred method. Sow sunflower seeds after the last frost and nighttime temperatures increased to more than 5º or 10º Celsius. Sow on loose soil at a depth of approximately 50 mm (2 inches), 1-2 feet apart. Water the seeds regularly to a height of 2 feet when the second set of leaves appears. Liquid fertilizer should be added to the water to feed on that moment.

Seeds must be sown directly in the field with the following space requirements: Giant, 3 feet in rows, 3-4 feet away; Intermediate type, 2 feet in rows, 3 feet away; and miniature type, 1 foot in rows, 3 feet away. Now that you have sunflower seeds in the ground, what should you do to succeed? If you grow several of them in the same area, be sure to place them at least twelve inches. Also, for larger varieties, such as mammoth grey, they may need little support as they grow. This is not always the case, but prevention is better than cure. While sunflowers are small, be sure to water them abundantly and, when they get bigger, you can relax a little in the water for a moderate daily watering.

Fertilizer needs.

Sunflower care is almost as simple as germination. Due to tall and thin stems, most sunflowers must be held by a pin or similar so that they do not fall in the wind. In addition, their growth rate means that they require a lot of nutrients, so it is a good idea to feed the plants in the growth phase. Both digging manure and applying liquid fertilizer works well. To promote flowers of larger sizes, phosphorus and potassium fertilizers should be applied before the flowering stage begins.

Control of pests and diseases.

Being a hardy plant, sunflowers do not have a serious problem with insect or pests. Only birds and squirrels are sometimes the ones that attack flowers. Similarly, no disease has been found that affects sunflowers. Unfortunately, many wild animals and garden pests, such as sunflower seeds, will dig in the ground to find them. It is better to spread the seeds and then dilute the plants after they reach approximately six inches tall. In this way, garden animals can eat until they are full, and you will still have many sunflowers.


The time to harvest seeds occurs when the backs of the head begin to turn yellow. You should collect the seeds as soon as possible so that the birds do not take them. There are several different ways to harvest. You can cut the stem of the stemmed flower, leaving the attached part of the stem. Then cover your head with a paper bag or canvas and hang it to dry. When the seeds dry, they fall from the head into the attached bag. If you prefer to pick them up in the yard, simply place the sack on the sunflower head, where it is planted. The bag will trap the seeds and prevent pests from picking them up.

For seed purposes, sunflowers are ready for harvest 80-120 days after sowing or sowing. There is also a specific maturity time for the variety you purchased according to the label specifications. The exact time to collect the seeds is when the flower begins to die and all the petals fall.

Cut the dried heads, leaving a few centimetres of stems, tie the stems and then hang them in a shaded and ventilated place. After drying after a month, extract the seeds by rubbing two loose heads to release the seeds. To use flowers as craft projects, flower arrangements and bouquets, simply cut the flowers before they dry and dry them for several weeks.


Now comes the fun! Toasting sunflower seeds is fun for the whole family. After collecting the seeds, you will want to soak them overnight in a simple saline solution. Mix a quarter cup of salt in a quarter of water and put the seeds. The next day, spread the seeds in a cookie and slowly bake in a warm oven at a temperature of 150 to 200 degrees. Occasionally, rotate the seeds during cooking. You will want to keep the seeds in the oven for about three or four hours. Place the hot seeds in glass jars and cover them well to store them.

In addition to roasting the seeds, you can save some for planting next year. Before soaking the seeds, store some and put them in a paper bag. Store the seeds in a cool dry place until the next planting season. Then you can start the process
