How to plant sunflower seeds?

Sunflower plants grow well in average to rich soils. They need to grow their roots deep and wide, to enable them to withstand strong winds. If you have a choice, sandy soils are not recommended, as they are easily uprooted in loose soil. Rich soil is important, when growing giant varieties. Contrary to it's name, we found they will tolerate some shade as we put them against an east wall of our house every year. However, they will grow their best in full sun. Deep roots help sunflowers to withstand most droughts. They will benefit from a dose of fertilizer when you apply it to the rest of your garden. Apply extra phosphorus and potassium when the flower bud begins to develop, to promote bigger blooms. Tip: If you are crowded for space, plant one or two sunflowers amidst your vine crops. One or two will not seriously shade the vines. Make sure not to plant them near their tap roots for the vines.

Will sunflowers grow in milk?

Can you get food poisoning from expired sunflower seeds if they're over 10 years old and out of the shell and an open bag?

Not likely. Food poisoning usually is a result of:

# The consequences of ingested enterotoxin # The consequences of ingested bacteria that produce toxins, but do not invade the mucosa, and are usually quickly cleared by the immune system Sunflower seeds do not contain any enterotoxins or compounds that can possibly degrade into enterotoxins in significant amounts, this rules out the possibility of #1.

Since sunflower seeds are dry (and will likely dry further in the open), bacterial and fungal growth is nil even in the 10-year period, and this rules out the possibility of #2. Therefore, unless the sunflower seeds are in contact with a contaminated area or is in a very humid environment, they will likely cause no problems upon consumption (other than tasting stale).
