Sowing Swamp Sunflowers: Sunflowers are generally sown in late winter or spring and will bloom 60 to 70 days after sowing. The seeds should be sown directly into the soil, with spacing between the seeds of at least 12 cm. After sowing, a 2 cm layer of fine soil should be used to cover the seeds. Then, the seeds should be watered before being covered with a layer of mulch. Once the seedlings appear, ventilate them well, reduce the humidity and temperature, and gradually expose the seedlings to sunlight. Two weeks after sowing, the seedlings will grow to about 5 cm. At this time, the seedlings can be transplanted into a 10 cm pot and cared for until planting out. The optimum soil temperature for planting sunflowers is 15 ℃.
All multiple orders of the same seed are put in the same bag. For example if you order 500 beefsteak tomato seeds x 3 then 1500 seeds will be put in the same bag. We do not send out 3 individual bags with 500 in each. This goes for all seeds unless they are listings of different seeds.
