Most gardeners sow fast-growing annuals, such as sunflowers, bachelor buttons, calendulas, zinnias and nasturtiums right into the garden. I agree that it's not worth the trouble to grow these seeds indoors for just three to four weeks, and also run the risk of transplant shock.
Sunflowers grow best in full sun, getting 6+ hours per day. They will grow in just about any type of soil, but because they have deep roots and are heavy feeders, you may want to amend the soil before sowing.Till the soil 12-18 deep and amend it with compost, seaweed, fish emulsion, or composted manure.hen, for the largest sunflowers, when your plants are 2-3' tall, thin them to two feet apart. When plants are closer together, they compete for nutrients and don't grow as large. Keep the planting area weed-free to eliminate nutrient and moisture competition.
