The seeds should be planted no bigger than an inch deep and about 6 inches apart. The strongest plants are 12 inches apart if you thin the seedlings after they hit 6 inches tall. If you want continuous blooms, sow a new row of seeds every two to three weeks, beginning at the top of the previous row. Sunflower seeds should be sown in late spring or early summer, but can be planted as early as April or May.

Do you plant sunflower seeds point up or down?
Place the sunflowers 1 to 2 inches deep, point-down, every 6 inches or so, and then cover them with a layer of mulch. If you want to plant the seeds directly into the soil, you’ll need to dig a hole about 6 to 8 inches in diameter and 2 to 3 feet deep.
The hole should be deep enough to allow the roots to grow through it, but not so deep that they can’t get out. If you dig too deeply, your seedlings won’t be able to get through the hole and they’ll die.
You can also use a garden trowel or a shovel to make a shallow hole, about 1/2 to 1 inch deep and 3 to 4 inches wide, that will allow your seeds to germinate. Make sure that the bottom of your hole is at least 3 inches from the top of any plants that may be growing in it.
This will help prevent root rot and other problems that can occur when roots get too close to the surface.
Can you grow a sunflower in a plastic cup?
If you don’t have a plant pot consider using yogurt pots, tin cans, plastic cups, old bottles (with holes in the bottom for drainage) or toilet rolls which are biodegradable and can be planted into bigger pots or into ground soil later. The compost should be evenly distributed throughout the pot if you sow one seed per pot and water.
Plant the seedlings in a sunny spot and allow them to grow for a couple of weeks before transplanting them into a larger pot or planting them in soil. If you want to plant the seeds directly into the ground you will need to dig a hole about 1/2 to 1 inch deep and cover the hole with a layer of compost.
This will keep the soil from drying out during the winter months. You can also use a garden trowel to help you dig the holes. Once you have dug your hole you can fill it with compost and plant your seeds in it.
How many sunflower seeds do you plant in one hole?

Do seeds need to be covered with plastic?
To speed germination, cover the pots with plastic wrap or a plastic dome that fits over the seed-starting tray. This keeps the seeds moist before they grow. If you see the first signs of green, remove the plastic and let the soil dry out for a few hours. When the plants are ready to be transplanted, place them in a pot with a drainage hole in the bottom.
The hole should be large enough to allow the roots to drain into the pot, but not so large that they block the drainage. If the hole is too small, the plant will not be able to get enough water to root itself and will die. To prevent this from happening, make sure that the holes are at least 1/2-inch in diameter.
You can also use a hole saw to cut a small hole for the root ball to pass through. Place the planting pot in an area with good drainage, such as a sunny window sill, and water it well. After a week or so, you should see some new growth on the top of the growing pot. Continue watering and transplanting until all of your plants have been planted.
Can you grow a seed in a cup?

Place the seed cups in a bowl of warm water and let them sit for a few minutes. The seeds will start to germinate in about a week or two, depending on the temperature of your water.
Should sunflower seeds sink or float?
If you want to open the seeds, crush them with a rolling pin and put them in a paper bag. The seeds will sink while the shells float. It is easy to gather them.
