I’m planting mammoth sunflower in zone 9b (FL). I started the seeds in containers and moved them to the ground. For some flowers, I dug holes and filled with garden soil. For others, I planted in the ground, which is sandy. Those seem to be doing okay, too. They get sun from sunrise to sundown. Would you plant them in sandy soil?

Sandy soils just require more watering and fertilising.
