Do sunflower grow better in pots or in ground?

Unless you grow a dwarf type of sunflower, such as "Teddy bear" you would not grow them in pots. Most sunflowers grow tall, and become rather top-heavy. Sunflowers need lots of room to grow--including the roots, which need to spread out beneath the soil in order to anchor the plant. Even muli-stemmed sunflowers, whose individual flowers are fairly small (for a sunflower), get top-heavy because of the number of flowers on the stem. So, if you absolutely MUST grow one in a pot, select the shortest cultivar you can, and still put that in an over-sized pot. So, sunflowers grow better in the ground, but it is possible and challenging to grow them in pots.

Do sunflowers undergo epigeal germination?

I'm no expert, but I believe yes: From: http://www.answers.com/topic/epigeal In botany, a seed is described as epigeal when the cotyledons of the germinating seed expand, throw off the seed shell and become photosynthetic above the ground. The converse, where the cotyledons remain non-photosynthetic, inside the seed shell, and below ground, is hypogeal. And http://www.answers.com/topic/cotyledon Cotyledons may be either epigeal, expanding on the germination of the seed, throwing off the seed shell and become photosynthetic above the ground; or hypogeal, not expanding, remaining below ground and not becoming photosynthetic. The latter is typically the case where the cotyledons act as a storage organ, as in many nuts and acorns. And http://www.answers.com/topic/germination

How do you grow the tallest sunflower?

Start with good quality seed.

Plant early indoors, or in a heated greenhouse, in a flower pot with potting compost. Better: plant several, so you can pick the best shoot for planting on. Keep the soil moist and warm until the seeds germinate.

Find a good spot. Somewhere which gets the maximum amount of sunshine. Somewhere near a wall, or a telegraph pole etc. which can support the sunflower as it gets taller. Somewhere with plenty of room for the roots to spread out. Big healthy roots = tall sunflower.

Dig the soil with a fork or spade. Dig down and loosen up the soil as much as possible so that the roots have an easy time. Remove stones you find. Mix in some fertiliser. Shop bought or homemade compost is good, well rotted manure is better. Work lots of it deep into your newly dug soil. Well fertilised ground = tall sunflower.

When the cutting gets its 3rd and 4th leaves, start to "harden" it. Put it outside , in it's pot, during the day and indoors at night. Keep it outside for longer periods so that it gets used to the climate. If the leaves get limp after it has been outside, it's getting too cold - keep it indoors more until the weather improves. This step is particularly important if you've planted early = better, as the sunflower will get a longer growing season (ideal for getting big).

Wait till the risk of night frost has passed. Dig a hole in your soil patch and transfer the sunflower - potting compost and all - into the soil. Press the soil down well all around (helps retain moisture).

And that's it! Make sure you water regularly, support it as it gets taller, pull out the weeds. A well prepared ground, and a well cared for sunflower will be the tallest.

Are sunflower seeds fattening?

They contain healthy fats which are necessary for aiding weight reduction, lowering cholesterol, enhancing immunity and nourishing the reproductive organs, skin, hair and bone tissue, effectively lubricating our bodies. These are the good fats, vitally important and necessary for life itself. And these fats help you to metabolize fat. They are so important that they are called essential fatty acids (EFAs). Your body cannot make EFAs, so you must get them through the foods you eat. Sunflower seeds are very high in EFAs, so they're very good for you! Avoid the roasted and salted brands though! Go for dry roasted (raw) and unsalted brands.
