Steps
Sowing sunflower seeds
- Usually sunflowers grow to their full potential and give seeds after 80-120 days, depending on the cultivar. [2] X Research Source If the growing season is shorter in your area, plant sunflowers 2 weeks before the last frost; most seeds can survive. [3] X Research Sources
- Roasted sunflower seeds cannot be grown, but you can plant bird feed sunflower seeds if the outer shell is still intact. [4] X Research Sources
- If you have a lot of seeds and don’t mind a low success rate, you can skip the above step and plant the seeds straight into the ground. Seeds sown directly into the ground usually take 11 days to germinate out of the ground. [5] X Research Sources
- If the growing season is longer in your area, try sowing your seeds in batches, 2 weeks apart, so you’ll have a flower garden for longer.
- For best results, you need to keep the tissue above 10ºC. [8] X Research Sources
Sowing sunflower seeds
- Unless your garden is often hit by strong winds, you should plant sunflowers away from trees, walls, and other objects that can block sunlight.
- Fertile soil should be reserved for giant sunflower varieties, as they require more nutrients. [13] X Research Source
- If planting in bulk, it is recommended that you sow the seeds in grooves about 75 cm apart or keep a distance that is convenient to use agricultural machines. [16] X Research Source[17] X Research Source
Sunflower care
- If there are deer in the area, you should use trellis to fence when the tree begins to produce leaves. You can use a 90cm wide trellis fence around the tree and use a bamboo tree or 1.8m high wooden stake to attach the trellis when the tree grows tall. Thus, the deer cannot destroy the tree.

- The period before and after flowering is very important, and a lack of water can derail this process. [23] X Research Source Continue watering the plants every week as flower buds begin to form.
- Skip this step if you want small flowers to fit in your bouquet or if you’ve planted them the right way from the start.
- Another option is to fertilize the soil once with a slow-release fertilizer.
- If left to the wild, sunflower seeds will fall to the ground and sprout next season. However, harvesting will protect the seeds from pests.
Advice
- Sunflowers are annual plants and will die after the flowers have faded.
Warning
- Sunflowers secrete chemicals that can inhibit the growth of potatoes or beans and can even kill weeds if grown naturally. However, these chemicals are not harmful. [28] X Research Sources
- Do not plant sunflowers against brick structures as the stems can get in between the bricks and damage the structure.
