Planting and Harvesting Sunflower Seeds
Planting Sunflower Seeds
The easiest time to plant sunflower seeds is when the spring frost is already gone. The seeds need to be sowed directly into the soil. For planting big sunflower seeds, make sure to dig the loose soil 1 inch deep and 4 to 6 inches apart. Ideally, this is done when the soil is thoroughly warmed (with soil temperature 55 to 60 degrees Fahrenheit). This is usually around mid-April til late May. As the planting is being done, make sure to make a light application of fertilization. This is to assure that there will be strong root growth. As a result, this will protect the seeds from being scattered over in the wind.
Experimentation in the plantings can also be done over 5 to 6 weeks. Moreover, remember to give adjustments or spaces to allow branching out of the plants. If low-growing varieties were used, space them out about 30 inches from each other. On the other hand, in the case of very small varieties, they should be planted closer together. When the plants reach six inches in height, cut them into two feet. If ever the birds go and scratch around for the seeds, it is a must to put the netting over the area where the seeds are planted. Then, wait until the seeds germinate.
Whenever the plants are watered, it should be done deeply but not too frequent as to allow their deep rooting.
Put the right amount of fertilization for the plants. Too much fertilizer may cause the stem of the plant to break during the fall.
For the tall cultivars and species, support is necessary. Bamboo stakes can be quite useful for this function because it has a single strong stem which provides enough support for the plant.
- Most of the time, sunflowers are insect-free. However, there may be gray moths which may lay eggs on the blossoms. When this happens, eliminate the worms from the plants
- Keep watch for squirrels or birds which may show interest in the seeds. This can be controlled by using barrier devices. Once the seed heads begin to mature and the flowers droop, a white polyspun garden fleece is utilized to cover them.
- There may be cases in which rust, powdery mildew and downy mildew cause fungal diseases. When these are seen, spray the plant with a general garden fungicide. 
How to harvest Sunflower seeds
The process of harvesting sunflower seeds is very easy. However, the decision on when to do the harvesting can make people a little confused . In order to know when to harvest sunflower seeds, here are some indicators on when to harvest sunflower seeds:

- Having an anti-oxidant agent, Vitamin E, the free radicals in the body are neutralized. If this function doesn’t work, the fat-containing structures and molecules, such as the brain cells, cell membranes, and cholesterol will be damaged.
- Vitamin E has a significant role in this case by decreasing the inflammation. This results to symptoms reduction, particularly in osteoarthritis, rheumatoid arthritis, and asthma.
Good effect on the nerves
- The sunflower seeds also contain magnesium. Magnesium is very important in the neurologic functioning. It works by interfering calcium on activating the nerve cells and instead, causing the nerves to relax. Therefore, letting the blood vessels and muscles relax as well.
- When magnesium is low in the body, calcium enters the nerve cell which causes it to deliver too many messages. This results to contraction.
- As an effect of low magnesium levels, the following occurs: soreness and fatigue, migraine headaches, higher blood pressure, and muscle tension.
- Tryptophan, an amino acid contained in sunflower seeds, aids in the serotonin production. Serotonin calms the brain, eases the tension, and promotes relaxation.
- Niacin which belongs in the B-complex group of vitamins helps in improving the GABA brain activity. This leads to anxiety and neurosis reduction.
- Folic acid, which is also contained in sunflower seeds, can help in the DNA synthesis. This is especially the case in mothers who are in their peri-conception period. Folic acid lessens or prevents the occurrence of neural tube defects in the baby.
Cardiovascular system improvement
- As mentioned above, sunflower seeds are an excellent source of vitamin E. Vitamin E is significant in the prevention and management of various cardiovascular diseases. This is because Vitamin E is an antioxidant which acts on destroying the free radicals to prevent oxidizing cholesterol.

- Cholesterol levels are also controlled through the mono-unsaturated acid (oleic acid) which lowers the bad cholesterol and increases the good cholesterol in the blood.
- According to research, there is a relationship between cancer and decrease selenium intake.
- Selenium has been found out to activate DNA repair and synthesis in damaged cells, block cancer cell proliferation, and cause apoptosis (a process in which the body does a self-destruct mechanism to eliminate abnormal or damaged cells).
- Selenium, when combined at the proteins’ active site like glutathione peroxidase, can aid in cancer protection.
- Glutathione peroxidase is utilized by the liver to eliminate the harmful molecules in the body.
- Vitamin E has been discovered to decrease the chances in having bladder cancer, colon cancer, and prostate cancer.
- Given the fact that sunflower seeds are high in magnesium, this means that they can aid in the improvement of bone strength. Magnesium works on the bones by lending their physical structure.
