If you want good blueberries you need to buy named cultivars as plants rather than seeds. I've never grown them so can't help you further I'm afraid.

flora is correct. If you want help you will need to provide more information. What zone are you in?

I agree with the others.
It is possible to grow blueberries from seeds but, the germination rate is poor, you have to either get stratified seeds or do that yourself.
You can get seeds and try it but it will take a minimum of 2 years from seed to fruit and like I said the germination rate sucks-some people get 0%.

Blueberries are routinely grown from cuttings, sections of blueberry stem that are about 5 inches long. The cuttings are taken from blueberry shrubs in later winter or early spring. They are also called scions. There would be discussion of this topic on the propagation forum. There are seeds found in blueberry fruit, and these should be viable. A plant grow from seed would be genetically unique, and might be superior in some way, but it would take time and effort to prove that.

The best thing to do would be to get some tissue culture plugs. They are very cheap and you wouldnt be out much money if you kill them. If you do grow them right you will have a very healthy plant the following spring with a small crop of berries. Im growing both cutting propigated blues and tissue culture blues. The TC plants are much more robust and sending out alot of canes from the base of the plant. IMO they are a superior plant after the first year of growth compared to a cutting plant. Havent grown seed plants but I dont see how they could even compair to a TC plant.
