Sunflowers are grown from seed sown directly in the garden after frost.

  • Direct sow seeds in average soil in full sun after all danger of frost.
  • When choosing a site consider that sunflowers need a well-drained soil.  They face the sun, so make sure they are in an open area of the garden. The taller varieties will cast shadows on other plants, so plant these at the north end of your garden.
  • Prepare the soil by removing weeds and working organic matter into the top 6-8 inches of soil; then level and smooth.
  • Most plants respond well to soils amended with organic matter. Compost is a wonderful form of organic matter with a good balance of nutrients and an ideal pH level, it can be added to your planting area at any time. If compost is not available, top dress the soil after planting with 1-2 inches of organic mulch, which will begin to breakdown into compost. After the growing season, a soil test will indicate what soil amendments are needed for the following season.
  • Sow seeds ½ inch deep in groups of 2 or 3 seeds. Space the groups 18-24 inches feet apart, depending on the variety.
  • Firm soil lightly, water and keep evenly moist.
  • Seedlings will emerge in 7-10 days.
  • Thin to one plant per group when seedlings have two sets of leaves.
  • Keep weeds under control during the growing season. Weeds compete with plants for water, space and nutrients, so control them by either cultivating often or use a mulch to prevent their seeds from germinating. 
  • Mulches also help retain soil moisture and maintain even soil temperatures. For annuals an organic mulch of shredded leaves lends a natural look to the bed and will improve the soil as it breaks down in time. Always keep mulches off a plant’s stems to prevent possible rot.
  • Keep soil evenly moist but not wet.
  • Once established sunflowers can tolerate drought.
  • No fertilizer is needed unless the soil is poor. Do not over fertilize.
  • Monitor for pests and diseases. Check with your local Cooperative Extension Service for pest controls recommended for your area.
  • Some varieties only produce one bloom so once the bloom is spent, the plant may be removed.
  • Remove plants after they are killed by frost in fall to avoid disease issues the following year.
  • Edible sunflowers will mature in about 3 months or more after sowing. To harvest the seeds, cut the heads off after the stalks are quite dry but before fall or winter rains come. Check the flower heads for maturity to see if the florets in the center of the flower disk have shriveled and the back of the flower head is turning yellow, or the head is starting to droop. Cut flower-heads with a foot of the stalk attached. Hang heads in a warm, dry, well-ventilated place so the seeds may fully ripen and dry. Cheesecloth, netting or a paper bag with holes punched in for ventilation should be placed over the head to protect the seeds and to collect those that may drop from drying.
  • Shorter varieties may be grown in containers. Be sure to use a commercial potting mix.
  • Pollenless varieties make terrific cut flowers.

Rated 5 out of 5 by from Stops joggers in their track! Very beautiful and easy to grow. She has a thick main stalk and sturdy branches. Gives out multiple blooms at a time. This wonderful plant has been withstanding the heavy rains and wind lately. My neighbors stop and stare. I've seen a few take pictures. I highly recommend this variety!

Rated 5 out of 5 by from Absolutely gorgeous! A real standout!! I have grown so many varieties of sunflowers. These are exceptional because I did not even stake them like I always do the others; yet it is impervious to the wind. These have very sturdy stiff main stems and multiple flowers. The color of the blooms is just indescribable. And the honey bees are just going crazy over them. I will have to plant some of these every year.

Rated 4 out of 5 by from Not sure if it's user error But only two of these seeds germinated for me. That's actually fine because how many sunflower plants do you really need? The one that's right where I want it is thriving! I had to pull a smaller one that was right next to it and put it in a container. I think it needs time to adjust before it starts growing again. I'm expecting great flowers. It's possible that garden critters ate the other ones I planted, so I hesitate to blame the seeds. I would suggest the strategy of planting about 5 seeds close to the location where you want the plant, to increase your odds of getting what you want where you want it.

Rated 5 out of 5 by from Amazing Flower! I cannot say enough good things about this sunflower! Excellent seed germination rate, incredibly beautiful flowers, can put up with whatever weather northern Virginia is dishing out, and they just keep going! I direct sewed these into the ground in early June, and they are STILL blooming lots of little flower heads into mid-September. Make gorgeous cut flower arrangements, attract lots of pollinators, and the stems are very sturdy. These are going to be a permanent fixture in my garden!

Rated 5 out of 5 by from All I can say is WOW! I planted these last year and while all the plants remained at about two feet tall, they bloomed for the entire growing season. The colors were remarkable! Some ranging more vivid than the picture shown here, and some more of a brown/burgundy with pale yellow tips. They are stunning. But be WARNED! You will have to chase away kids trying to pick them. Lol. I hope you enjoy these as much as I did. Cheers.
