If you are thinking of sowing Sunflower seeds directly in the soil you will want to do this in mid-April. Make sure you put the seeds carefully in the ground and cover the seed with soil. Make sure you water the newly planted Sunflower seeds. You should not miss the Basic Steps of Organic Farming. Space Sunflower seeds about 6 inches apart in a shallow trench between 1 and 2 inches deep.
In sandy soil , 2 inches deep is better. Cover and keep watered until Sunflower seeds sprout in 7 to 10 days. Then, place the Sunflower seeds at a depth of 3 cm along the furrows in which the fertilizer mixture is placed and cover with soil. Put 2 seeds per hole. The seed rate is the number of seeds planted per hectare ha to ensure a normal density of sprouts and a maximum crop yield. The seed rate is 8 to 10kg of well-filled seeds per hectare.
This can be done just before sowing. It is compatible with biofertilizers. Then, such seeds should not be treated with fungicides. Then, treat the seeds 24 hours before sowing. Sunflower seeds are planted a one-half inch deep and Sunflowers are an oil-rich seed, they require slightly more water for germination than many other seeds.
This requires watering the ground thoroughly outdoors after planting and not allowing the soil to dry out completely until seed germination occurs. Indoors, the soilless media is completely saturated and also allowed to drain before 2 or 3 seeds are planted in each pot.
Then, covering the pots with clear plastic wrap slows evaporation. Outdoor planting time is several weeks after the last spring frost when the soil has warmed thoroughly. The Sunflower seeds will sprout in 10 to 14 days outdoors. Indoors, where the growing environment can be more closely controlled, germination often takes place in 6 to 10 days. Sunflower seeds do not need light for germination. The plants grown indoors in pots, the plastic wrap is removed at the first sign of germination and the uncovered pots are located in bright, indirect light.
Outdoors, thinning small varieties to 6 inches apart and large varieties to about 3 feet apart allows ample light and airflow around Sunflower seedlings. This phase takes up to 8 days. During germination, plant roots will develop from the seed and a shoot will push through the surface of the soil. The shoot is looking for sunlight because all plants require sunlight to grow.
Germination occurs from mid-April to late-May, depending on when you plant your seeds. Different Sunflowers need different planting depths and spacing. How to grow Sunflowers from seed and how deep to plant Sunflower seeds depends on specific Sunflower cultivar. Space seeds 6 inches apart. Plants must be thinned out in a few weeks to the proper spacing. If soil temperatures are just right, Sunflower seedlings will sprout up in about 10 to 14 days.
Growing Sunflower seeds requires some space. To start Sunflowers indoors, plant 3 seeds per each 3- to 4-inch peat pot. A soilless planting media will give you the best drainage system. Indoor germination happens in 6 to 10 days. You can enjoy continuous blooms through summer by planting Sunflower seeds every couple of weeks.
With consecutive plantings, you will have beautiful Sunflower blooms right up until the first frost of fall. Once the Sunflower seedlings have their first set of true leaves, thin the seedlings to the recommended row spacing for variety. Small Sunflowers can require only 6 inches between each plant, while large varieties might need up to 3 feet. Closer spacing is possible for garden aesthetics, but crowded plants will produce smaller Sunflower flowers.
Indoor Sunflower seedlings must be reduced to one seedling per cup. Simply select the strongest Sunflower and pinch back the others. To harvest the seeds of Sunflower, wait until your Sunflower droops and turns brown.
Then, cut the stem leaving 4 inches from the head of the Sunflower. You should store the Sunflower head upside down in a dry and breathable bag. Your seeds must be ready to harvest within to days after you planted the flower. The exciting part about growing sunflowers is that children are rewarded almost immediately with a tiny seedling pushing through the earth. At first, it has two tiny oval leaves growing out of its delicate stem. As it matures, more leaves appear that have a heart shape.
Sun is vital at every stage of sunflower growth. After about 35 to 65 days, tiny buds appear. This is called heliotropism. The flower head returns to its east-facing starting point during the night, and when the sun emerges, its trip begins again.
Birds, squirrels and deer are attracted to the sunflower seeds. Protect your crop by erecting a barrier or covering the plants with garden fleece. A gentle, organic garden fungicide can be sprayed on the flowers if mildew or rust are discovered.
When the back of the head turns brown, snip it off the stem at about 6 inches below the face. Avoid wildlife feeding on the seeds by covering them with cheesecloth or bringing the heads to a safe place until they are ready for harvesting. Hang them upside-down away from insects and rodents. Place the heads in a container to dry out, shaking them gently to remove the mature seeds.
Rub your hand across the face as it dries or scrape it against a rough surface to loosen the seeds. Roasted seeds, lightly salted, are healthy for snacking. Crack the pod to release the meat inside. Store in an airtight, covered container. Seeds can be used as feed for birds and squirrels during the cold season or replanted the following spring to begin the cycle of germination of sunflower seeds.

By Jann Seal Updated June 08, First, keep the soil moist, but not wet.
Do not over water the soil, and consider using a cloche to help you to get the right moisture level. Second, keep the soil loose. Do not compact the soil by pushing down on it either before or after planting your seeds. When there is more space between soil particles, there is more space for air and water, both of which are necessary for seed germination.
Sunflower seeds should be planted 1 to 2 inches deep for ideal germination. If you plant the seeds too deep, they may fail to germinate or reach the soil surface. You can learn more about proper planting depth for seeds in my article here. If you want to make your sunflower seeds germinate faster, there are several important actions you can take. First , protect your seeds from extreme heat and cold. As mentioned earlier, temperature is one of the most important factors that affect seed germination.
If it is too cold to plant seeds outside, then start your seeds indoors. This gives you a head start on the growing season, and minimizes the danger of late spring frosts killing your seedlings.
This is especially helpful if you live in an area with a short growing season. Second , ensure that the soil is moist not wet! Seeds will not germinate if there is not enough moisture in the soil and air. Consider a cloche for this purpose. Third , make sure that the soil has enough air circulation. This means that you should avoid compacted soil both before and after planting. It also means that you should avoid over watering your soil.
Fourth , remember that sunflower seeds do not need light to germinate. If you start sunflower seeds indoors, give the seedlings bright overhead lights after germination. Fifth , make sure to plant your sunflower seeds according to the proper depth and spacing. Sunflower seeds should be planted at a depth of 1 to 2 inches 2. If planting in rows, space plants 6 inches apart 2 per foot. When the first true leaves appear, thin the plants to 1 per 2 feet to prevent competition between plants.

For more information, check out this article on seeds and seedlings from the Penn State University Extension. You can soak your sunflower seeds before planting to encourage faster germination. Put them in clean water and let them sit for up to 24 hours before planting. However, this is not required — as long as the growing medium is moist and warm, the sunflower seeds should germinate well.
Yes, you can germinate sunflower seeds in a paper towel. The paper towel holds moisture and allows the seeds to breathe, serving as an alternative growing medium. To germinate sunflower seeds on a paper towel, wet the paper towel until it is damp not soaking wet.
Then, lay out the sunflower seeds so that they are separated not touching.
