How to Know When to Plant Sunflowers

Transplant Sunflowers?

Like many types of flowers, sunflowers can be grown both indoors and outdoors. Fill the tray with potting mix, plant each seed so that about 1/2 inch of the mix covers the top of the seed, and water the soil until moist. Like other flowers, sunflowers should not be transplanted outdoors until the chance of an overnight frost has passed for the season. Since letting a sunflower grow any taller than a few inches before transplant can weaken the structure of the plant, try not to start your sunflower plantings until late enough in the spring that you can transplant the sunflowers as soon as they reach the correct height. Once you transplant sunflowers outdoors, care of the plants is simple.
