Sunflowers are a very easy garden crop to grow. Sunflowers tolerate most soil types. Their roots grow deep and spread wide, giving them the ability to withstand a fair amount of drought as well as tolerate some soil disturbance/p>
Start seeds in flats or sow them directly into the soil. Plant them so that they get full sun. They grow best in fertile, moist, well-drained soil with a lot of mulch. Soil must warm to at least 45º F (preferably above 50ºF). For plant to develop fully flowering heads, do not add too much nitrogen. p>
