When to plant sunflower seeds. Sow sunflower seeds from April to May, individually in 10cm pots of peat-free, multi-purpose compost. Plant out into the garden when all risk of frost has passed, from early June.
Should I soak sunflower seeds before planting?
We recommend our USA Grown Raw Organic Sunflower Seeds. Start the process by soaking the seeds for 11/2 – 2 hours at room temperature. A good ratio will be about half to one cup sunflower seeds with two cups water. Next, drain and rinse the seeds thoroughly (you’re getting rid of that pesky phytic acid!).

Can you just scatter sunflower seeds?
For many kinds, yes. Find out when the plants normally set seeds, and scatter then, or just before a good rain after that time. I usually sow in the fall after it has rained some, but more is expected, so that the seeds stay where I toss them.
What is the best month to plant sunflower seeds? – Related Questions
Do you plant sunflower seeds point up or down?
The narrow end of the seed is where roots will emerge, so putting this end down saves the plant from having to right itself in the ground. Place the sunflowers 1 to 2 inches deep, point-down, every 6 inches or so, and then cover them up.
Do sunflowers come back every year?
Sunflowers can’t announce their intentions, but the perennial varieties will indeed return to your garden next season without involved effort from you. Other cultivars, of course, must be reseeded, but that does give you a chance to plant different varieties in new colors or heights.
What is the fastest way to germinate sunflower seeds?
Sunflower seeds take 4 to 11 days to germinate, depending on soil conditions (temperature and moisture are the most important factors). To speed up germination, plant sunflower seeds 1 to 1.5 inches deep in warm soil (70 to 78 degrees Fahrenheit) that is damp, but not soaked.
How long does it take to germinate sunflower seeds?
If soil temperatures are just right, sunflower seedlings will sprout up in 10 to 14 days. Growing sunflower seeds requires space. To start sunflowers indoors, plant three seeds per each 3- to 4-inch peat pot. A soilless planting media will give you the best drainage.
Are sunflowers easy to germinate?
You can even find sunflowers that only grow 12 inches tall—the perfect size for pots on a porch. Sunflowers grow easily from seed, so much so that these bloomers often plant themselves beneath birdfeeders. If you’re sowing intentionally, it doesn’t take long to germinate sunflower seeds.
How do you germinate sunflower seeds in a Ziplock bag?
Do sunflower seeds need to be covered to germinate?
To give them the best start, the seeds will need to be protected until they’ve germinated, and seedlings are around 5cm tall; it’s best to do this indoors to avoid any damage from frost.
Do sunflower seeds need cold stratification?
Sow perennial sunflower seeds either in the fall or in the spring after the last frost. (Get seeds here.) If sowing in the spring, the seeds must first be cold stratified, which means they need a period of cold to germinate. To cold stratify the seeds indoors, start about 8-10 weeks before your spring frost date.
Can you use Saran Wrap to germinate seeds?
The basic idea is to sow your seeds in pots as normal, water them well, and then secure a layer of clear plastic over the pots to stop the moisture evaporating. You can use any plastic you have handy, such as cling wrap, freezer bags, or even waste food packaging, and fix it into place using a rubber band or string.
Is it better to germinate seeds in soil or paper towel?
Many seeds germinate much quicker in paper towels (versus seeds that are started in soil). The heat, moisture, and controlled conditions inside a plastic baggie help them germinate in only a few days (or less, depending on the seed).
What thing are not good for seed germination?
Soil is too wet/dry
Water is needed to initiate the process of germination. When planting in dry soil, your seed might not absorb enough water to start the germination process, as moisture will be absorbed from the seed and shoot before it even has a chance to establish.
Paper towels, filter paper or even newspaper provides an excellent medium for germinating seeds. They are pathogen-free and make it easy to control the moisture content for proper germination. This method also takes the guesswork out of knowing if your seeds have germinated since you can easily observe them.
Can you use toilet paper rolls to start seeds?
Plant the toilet paper seed pods in the garden, cardboard tube and all. If the cardboard is sticking up above the soil’s surface, simply tear off any excess. If you don’t, it will wick moisture away from the roots. You can also cut off the bottom and just plant the tube of dirt that was sitting in the toilet paper pod.
Is it better to start seeds in soil or water?
For the best results, seeds should also be started in a fluffy, fine-textured soil. Or, in a sterile soilless seed-starting medium. Once seeds germinate and start their life as a seedling, they need ample bright light right away. Seedlings may also need protection from pests or inclimate weather.
Should seeds float or sink when soaking?
One method to check for seed viability is the water test. Take the seeds and place them in a container of water. Let the seeds sit for 15 minutes. If the seeds sink, they are still viable; if they float, discard, because they probably will not sprout.
What seeds should not be soaked before planting?
By soaking the seed, it enables the new growth from the inside to push through the hard shell and grow. The seeds that could benefit from a good soaking include: corn, pumpkin, beans, chard, beets, and peas. The seeds you shouldn’t soak include: carrots, lettuce, radish, celery, turnips, and spinach.
