Find answers about growing yellow sunflowers, choosing planting locations, and collecting seeds after flowering.
Sow yellow sunflower seeds about 1 inch deep in fertile, well-drained soil after the danger of frost has passed. Choose a location with full sun, water consistently while the seedlings establish, and leave enough space for the selected variety to grow. Direct sowing generally helps sunflowers develop without unnecessary root disturbance.
Yes, dwarf and compact yellow sunflower varieties can grow in containers with drainage holes. Choose a pot large enough for the mature plant and its roots, use well-drained potting mix, and place the container in full sun. Tall varieties generally need larger containers and may require additional support.
Allow the flower head to mature until the back turns yellow to brown and the seeds develop fully. Protect the head from birds if you intend to collect the seeds. Cut it with a section of stem, allow it to dry in a well-ventilated place, and remove the seeds when they are dry. Seeds intended for replanting should come from a correctly identified variety; hybrid plants may not produce seedlings identical to the parent.
