Should I soak sunflower seeds before planting?

How do you know when sunflower seeds are ready to plant?
Leave the seeds for about three days and then check them every day for a week. When a root pokes through the seed, that seed has germinated.

Should all seeds be soaked before planting?
Soak the seeds for any longer and they might rot. The seeds swell as water penetrates the seed coat and the embryo inside begins to plump up. I presoak just about everything except for the tiniest seeds. But I’m always careful not to presoak my seeds until the night before planting them in pots or in the garden.
What seeds should not be soaked before planting?
Avoid soaking small seeds such as lettuce, radish, and so on. Germination of these species often doesn’t need a lot of help, and wet seeds are much more difficult to handle, leading to over-sowing and waste. Lastly, tropical native plants like chillies need a long growing season to ripen their fruit.

Sunflowers can be sown straight in to the ground where they are going to flower, so make sure the space you are going to sow is weed free, by using a trowel to remove the weeds. Rake the soil to a fine tilth (a fine crumbly texture) and make some drills 12mm deep. Watch your sunflower grow and grow and grow.

Are sunflowers easy to grow?
Growing sunflower plants is easy because they’re heat tolerant, pest resistant and fast growing. They’re native to North America so they can adapt to conditions in most locations. You can use them for cut flowers, leave them on the stalk for a gorgeous outdoor display in your garden, or harvest and eat their seeds.

Do I plant the whole packet of seeds?
In general, the larger the seed, the smaller amount of seeds should be planted in the same hole or cell. These types of seeds take up more space and grow roots very quickly once germinated. Multiple seeds can still be planted together, but I recommend not planting more than two seeds per hole with these larger seeds.
