Answer 4

It depends on which variety of sunflower, and when it was planted some of the larger sunflowers can take 100 days to produce. It takes at least 90 days.

If your plant is growing and is healthy you just need to be patient the flower should appear any day. There is still plenty of time.

Here is a site to give you all the information you should need including how to roast them.

Answer 5

If your fertilizing it with a high nitrogen fertilizer such as all purpose miracle grow ..then stop...This will give you all leaves and no or very few blooms..they need some fertilizer with high phospherous and pottasium based fertilizer such as miracle grow 'bloom booster' which drops the nitrogen content  and increases the phosphrus and pottasium content..Read under "how to grow sunflowers" on this link concerning the fertilizer..
