Sunflowers are beautiful if grown outside in your garden,\nand the seeds are nutritious and delicious for people and birds alike. But what if you want to grow them in\ncontainers, either indoors or outdoors on your patio? I did some searching to find out if this is\npossible, and the best practices for doing so.\n\n\n\nSo, can you grow sunflowers in pots? Yes, you\ncan grow sunflowers in pots. You should\nuse a pot that is at least 18 inches (46 centimeters) wide by 18 inches\ndeep. For sunflower varieties taller\nthan 3 or 4 feet (1 meter or so), you should support the plant with stakes as\nit grows.\n\n\n\nAlthough you can grow sunflowers in pots, there is more to\ntake into account, such as the soil you use and how much water or sunlight your\nplants get.\n\n\n\nCan You Grow Sunflowers In Pots?\n\n\n\nYou can grow sunflowers in any type of container including\ngrow bags, raised beds, and of course, ordinary gardening pots. You can leave the potted sunflowers either\nindoors or outdoors. But just how big\nshould a pot be to grow sunflowers?\n\n\n\nHow Big Should A Pot Be To Grow Sunflowers?\n\n\n\nThe size of the pot you need to grow a sunflower will depend\non the variety that you choose. For most\nvarieties, you should be safe with a pot that is 18 inches (46 centimeters)\nwide, although some sunflowers have a spread of 24 inches (61 centimeters) or\nmore.\n\n\n\nPots should be at least 18 inches wide and 18 inches tall to support sunflowers as they grow - use even larger pots for taller varieties.\n\n\n\nAs far as depth, a pot that is 18 to 24 inches (46 to 61\ncentimeters) deep should be sufficient for most varieties, since sunflower\nroots grow 1 to 3 feet deep.\n\n\n\nHowever, you may want to choose a deeper and wider pot with\nmore volume for larger varieties. Remember,\nsome sunflowers can grow to a height of 6 feet or taller! These will require more weight in the pot to\nkeep them from falling over as they grow, so plan accordingly.\n\n\n\nHere are a few different varieties of sunflowers in each\nheight category:\n\n\n\nShort: Ms. Mars \u2013 this sunflower has dark red or purple coloring in the flower and stems. It will grow to a height of 20 to 30 inches (51 to 76 centimeters), and will spread out to a width of 18 to 24 inches. For something a little different that won\u2019t grow out of control indoors, check out Ms. Mars Sunflowers on Burpee\u2019s website.Medium: Sunny Bunch \u2013 this sunflower has the usual yellow color you would expect on the flowers, and it grows to a height of 24 to 36 inches (61 to 91 centimeters). This sunflower only spreads out to a width of 12 to 16 centimeters, making it nice and compact for small indoor or garden spaces. For more information, check out Sunny Bunch Sunflowers on Burpee\u2019s website.Medium: Busy Bee \u2013 this sunflower also has the usual yellow color of sunflowers, the same as Sunny Bunch. However, Busy Bee sunflowers grow a bit taller, from 36 to 48 inches (91 to 122 centimeters) tall. The spread of this sunflower is only 12 to 16 inches, making it another great choice for small areas where you need a compact plant. Check out Busy Bee Sunflowers on Burpee\u2019s website.Tall: Del Sol Hybrid \u2013 this sunflower matures early, just 50 days after planting, and it has the usual yellow color of sunflowers. However, it can reach a height of 60 to 72 inches (152 to 183 centimeters), making it a great conversation piece if you can grow it indoors. The spread of this sunflower is only 8 to 12 inches, making it super compact \u2013 it probably won\u2019t go outside the boundaries of its pot if you stake it properly! For more information, check out Del Sol Hybrid sunflowers on Burpee\u2019s website.\n\n\n\nIt is possible to find sunflower varieties with all kinds of beautiful colors.\n\n\n\nYour choice of sunflower variety will depend on how much\nspace you have available in your home (vertical as well as horizontal!) or\ngarden. Remember that sunflower seeds can\nbe a great distraction to keep birds away from other plants that you value\nmore, such as berries.\n\n\n\nWhat Type Of Soil and Fertilizer Does A Sunflower In A Pot Need?\n\n\n\nAs with most plants, sunflowers will do best in loose, well-draining soil. You can buy a potting mix containing perlite or vermiculite, or create your own. If you\u2019re not sure which to use, check out my article on perlite and vermiculite.\n\n\n\nThe soil pH should be between 6.0 and 7.5 (slightly acidic to slightly basic). For more information on growing conditions, check out this article on growing sunflowers from the Old Farmer's Almanac website.\n\n\n\n If you are using your own compost or soil from your yard or garden, make sure to test the soil if you are worried about pH or nutrient imbalances. For more information, check out my article on how to do a soil test.\n\n\n\nPlant your sunflower seeds 1 to 2 inches deep in the\nsoil. Then, keep the soil moist for the\nfirst week or two until the seeds germinate. \nStart the seeds right in the pot, since sunflowers do not tolerate\ntransplantation very well.\n\n\n\nAs your plant grows, be sure to provide fertilizer if needed \u2013 sunflowers are heavy feeders. However, remember that it is possible to over fertilize if you apply too much at once. For more information, check out my article on over fertilizing plants.\n\n\n\nHow Much Water Do Sunflowers Need?\n\n\n\nAs mentioned before, keep the soil in the pot wet for the first week or two until germination. Then, you can let up on the watering a bit, since you don\u2019t want to cause root rot by keeping the soil constantly wet. For more information, check out my article on over watering your plants.\n\n\n\nSunflowers in pots need to be watered more often than their siblings planted in the ground outside.\n\n\n\nRemember that the soil in pots dries out much faster than the soil in the ground. This means that you cannot forget about your potted sunflowers for as long as you could your ordinary plants outside.\n\n\n\nAlso keep in mind that clay and plastic pots have different properties as far as how much water the soil will retain. For more information, check out my article on clay versus plastic pots.\n\n\n\nHow Much Sunlight Do Sunflowers Need?\n\n\n\nSunflowers will do best if they have direct sun, meaning 6\nto 8 hours of sunlight per day. If your plants\nare indoors, put them near a window where they will get the most sun (in the\nnorthern hemisphere, this is the south side of the house).\n\n\n\nMake sure your sunflowers get full sun - 6 to 8 hours per day!\n\n\n\nFor outdoor plants, you can put the pots anywhere that is\nnot too shady due to trees or structures like sheds, barns, or your house. If your yard is shady, try putting the pots somewhere\non the south facing side of the house.\n\n\n\nHow To Support Sunflowers As They Grow\n\n\n\nMany of the short and medium varieties of sunflowers will\nonly grow to a height of 2, 3, or 4 feet. \nThese may not need any support at all, although there is nothing wrong\nwith staking a 4 foot tall plant.\n\n\n\nThe taller plants that grow 5 to 6 feet or taller will almost certainly need support if grown in a pot. For one thing, the height of such a sunflower means that the entire pot is more likely to tip over as it grows.\n\n\n\nAlso, if you are growing outside, tall sunflowers without support are more likely to be blown over in a gust of wind or a storm. For more information, check out my article on protecting your plants from wind and storms.\n\n\n\nFor sunflowers that are 5 to 7 feet tall, you can drive a\nstake (such as bamboo or metal) deep into the soil inside the pot that the\nsunflower is growing in. Make sure to do\nthis before planting the seed. If you do\nit when the plant is established, you can harm the roots.\n\n\n\nStakes can be made of bamboo, wood, metal, or plastic, as long as they can provide support for your sunflower!\n\n\n\nThen, use twine to tie the sunflower to the stake at\nintervals as the plant grows, using twine (don\u2019t tie too tight!)\n\n\n\nFor taller, heavier sunflowers, you may want to put\nadditional weight in the pot to keep the whole thing from falling over. Choosing a larger pot and filling it with\nsoil is one way to do this.\n\n\n\nYou can also choose a heavier pot made of metal or ceramic\nto add extra weight. You can even put\nsome stones on top of the soil to add weight and keep the pot from falling\nover.\n\n\n\nIf you are still worried that the pot, stake, and sunflower setup\nwill fall over, then get yourself another pot. \nPut the pot right next to the first one with your sunflower. Fill the second pot half way with soil and stick\na stake into the soil.\n\n\n\nTall sunflowers are more likely to need support as they grow, or else they may fall over, damaging the plant and making a mess.\n\n\n\nThen, fill the pot the rest of the way with rocks. Finally, use this second stake as extra\nsupport to hold up the sunflower and keep it from falling over.\n\n\n\nIf you have another short plant that you want to grow that\ndoesn\u2019t need support, you can put it in the second pot. However, you might want to use only soil,\ninstead of filling it with rocks to make it heavier.\n\n\n\nConclusion\n\n\n\nNow you know that growing sunflowers in pots is a definite possibility.\u00a0 Even if your house isn\u2019t tall enough to grow a world-record sunflower inside, you can still enjoy some sunflower seeds without the birds stealing them first.\n\n\n\nIf you want other plants with yellow flowers for keeping indoors, check out my article on 10 houseplants with yellow flowers.\n\n\n\nI hope that you found this article helpful \u2013 if so, please share\nit with someone who can use the information. \nIf you have any questions or advice about growing sunflowers in pots,\nplease leave a comment below.
