How do you harvest sunflower seeds?
In this section we will understand how do you harvest sunflower seeds. Let us understand how to get seeds from sunflowers. Check your sunflower seeds and monitor them regularly after you see them wilting. Wilting in simpler words means when flowers bend and starts to die or become limp or flaccid. The back of flower head is called calyx. When the backs of the flower head are yellow and start becoming brownish it is the time for their harvest. By this time the outer petals would have fallen down. The seeds mature long before this. Since the heads of the flower are moist they are allowed to dry before harvest. At this time the seeds are flat and shrunken.
Do not let the seeds to fully mature on the stalk. If they mature, they will be easily eaten by birds and squirrels. To protect them from birds and squirrels put a brown paper over the flower head to cover it. In order to prevent the ripening seeds to fall out, tie it below with a string. Avoid using plastic bag. It will stop breathing of flower and result in developing mold. Then it will take time for the plant to die. Paper bag should be left in place till this happens.
Daily check the progress by removing the bag. As soon as the flower head turns dark brown and flower looks to be dying seeds are ready to harvest. By this time most petals will fall down. Measuring 12-18 inches from lower part of bag cut the flower stalk. Use a sharp knife or a pair of pruning shears for cutting. If there any remaining leaves on the stalk remove them. Thus we understand how are sunflower seeds harvested.
How to dry sunflower seeds before removing from the stem.
In this part, we will understand how to dry sunflower seeds. Select a ventilated, warm, and dry room indoor or outdoor. This could be a shed or barn. Hang the stem with bag upside down. Keep it in this position for 1-5 days until the flower head gets dried. The sunflower bag should be checked daily and vigorously shaken. Inside the bag, loose seeds will make a rattling noise. If so, it is an indicator that the seeds are ready. Otherwise, it means they are not dry enough and ready. Now open the bag and feel if the flower head has completely dried. In the flower head, lightly brush your fingers over some seeds. The seeds will be ready for storage if falling down easily.
When drying it, ensure there is ample circulation of air. Stacking one over other should be avoided. This will prevent them from losing moisture and even get rotten and decay. How to dry sunflower seeds is not difficult process but quite simple but requires due attention.

Washing and drying the sunflower seeds for storage.
When the seeds have been removed, again wash them and dry them before storing and consuming them. Make sure to take some important steps keeping in mind how you want to use the seeds. They should be simply washed and dried if you are saving them for replanting or feeding the animals.
