Here’s how to grow sweet potato vine without babysitting it all summer: plant rooted slips or nursery starts about two to three weeks after your last frost once soil hits 65\u00b0F, space them 12 to 18 inches apart in full sun to part shade, and keep the soil evenly moist for the first two weeks until roots take hold. After that, this plant mostly takes care of itself. It is one of the toughest, fastest-covering trailing plants you can put in a container or a bare bed.<\/p>\n
But there are a few things almost nobody tells you until they’ve already gone wrong. The biggest one: most people plant the wrong thing entirely<\/strong> and wonder why nothing happens for weeks. There’s also a pruning mistake that turns a lush vine into a bare, leggy mess by August, and an honest answer about whether you’ll ever get edible potatoes out of the ornamental kind everyone buys at the garden center.<\/p>\n Stick around for all of it, including the save-and-screenshot Sweet Potato Vine at a Glance<\/strong> card at the very bottom with every number you’ll want on hand this weekend.<\/p>\n Sweet potato vine is a tropical plant at heart, even though it shrugs off heat like nothing bothers it. It hates cold soil far more than it hates hot sun.<\/p>\n Wait until nighttime temperatures<\/strong> reliably stay above 55\u00b0F and soil temperature has climbed to at least 65\u00b0F. Planting into cold, wet soil is the number one reason slips or starts just sit there rotting instead of growing. In most of the country that means two to three weeks after your last spring frost date, not the same weekend you plant your tomatoes.<\/p>\n In zones 9 through 11, sweet potato vine often overwinters outdoors or self-seeds from tuber remnants left in the ground. Everywhere colder, it’s grown as a warm-season annual.<\/p>\n Get the timing right and the spot right, and the growing part takes care of itself.<\/p>\n <\/p>\n Sweet potato vine wants full sun for the boldest color and thickest coverage, though it tolerates part shade, especially the darker-leaved varieties, which actually hold their color better out of harsh afternoon sun.<\/p>\n Soil needs to drain well.<\/strong> This plant is related to the edible sweet potato, and like its cousin, it will rot in soggy, compacted ground before it ever gets going. Loosen the top 8 to 10 inches and work in some compost if your soil is heavy clay.<\/p>\n In containers, any decent well-draining potting mix works fine. Skip garden soil in pots, it compacts and holds too much water.<\/p>\n Now for the part that trips up more people than anything else: what you actually plant.<\/p>\n <\/p>\n Here’s the mistake that ruins the first month for a lot of first-timers: they buy a grocery-store sweet potato, expect ornamental vine, and end up with something completely different, or they plant an ornamental slip too deep and too early and it just sits.<\/p>\n Ornamental sweet potato vine (grown for foliage, sold in nursery flats or as small potted starts) and edible sweet potato (grown from slips for the roots) are the same species but bred for opposite goals. Know which one you bought before you plant it.<\/p>\n <\/p>\n <\/p>\n Get through the first two weeks and the plant shifts into another gear entirely.<\/p>\n <\/p>\n Right after planting, keep soil consistently moist, watering every two to three days if there’s no rain, until you see new growth pushing out, usually 10 to 14 days.<\/p>\n Once established, sweet potato vine turns surprisingly drought-tolerant. Check soil an inch down<\/strong> before watering; if it’s still moist, skip it. Overwatering established plants causes far more problems than underwatering, including root rot and yellowing lower leaves that people mistake for a nutrient issue.<\/p>\n If you assumed more fertilizer means more growth, that guess backfires here. Heavy nitrogen feeding pushes this plant toward all leaf and stem at the expense of root development, and in hanging baskets it just means more pruning for you. A single balanced feeding at planting time, or one light monthly feed through summer, is plenty. Containers dry out faster and appreciate that monthly feed more than in-ground plantings do.<\/p>\n Now, about that leggy, bare-stemmed look by midsummer.<\/p>\n <\/p>\n The sign almost everyone misreads is long, bare vines with leaves only at the tips. People think the plant is dying or under-fed. It isn’t. It’s just doing what vines do when left unpruned: chasing length instead of filling in.<\/p>\n Pinch growing tips<\/strong> back by 3 to 4 inches every few weeks starting a month or so after planting. This forces branching lower down and keeps the plant dense instead of stringy. It feels wasteful the first time you do it. It is not.<\/p>\n Beyond that, this is a genuinely low-drama plant. Watch for:<\/p>\n Sweet potato vine, incidentally, is considered mildly toxic to pets if ingested in quantity. If your dog or cat eats a significant amount and shows vomiting or lethargy, call your veterinarian rather than waiting it out.<\/p>\n Handle the pinching and drainage, and this plant will outgrow almost anything else you plant near it.<\/p>\n <\/p>\n Here’s the honest answer to the question everyone eventually asks: will I get sweet potatoes out of my ornamental vine?<\/strong> Almost certainly not worth eating. Ornamental varieties can form small tubers, but they’re bred for foliage color and vigor, not flavor or size, and the harvest is usually disappointing.<\/p>\n If you’re growing the edible type from slips, tubers are ready roughly 90 to 120 days after planting, when lower leaves start yellowing and vines slow their spread. Dig gently with a fork well outside the plant’s base to avoid piercing the roots, and let them cure in a warm, humid spot for a week or two before storage to develop full sweetness.<\/p>\n For ornamental vine, there’s no harvest at all in the usual sense. It just grows, cascades, and gets cut back or composted at frost. Some gardeners bring a cutting indoors on a windowsill to overwinter and replant next spring.<\/p>\n Either way, once frost is forecast, the vine’s season is over for the year.<\/p>\n <\/p>\n Get the planting depth, drainage, and that first pinch right and this plant does the rest of the work itself.<\/p>\n Skip the pinching, and you’ll spend August wondering why your thick green carpet turned into a handful of bare, trailing strings.<\/p>\n","protected":false},"excerpt":{"rendered":" Here’s how to grow sweet potato vine without babysitting it all summer: plant rooted slips or nursery starts about two to three weeks after your last…<\/p>\n","protected":false},"author":6,"featured_media":2023,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"lfe_reviewer":"","footnotes":""},"categories":[597],"tags":[598,600,599],"class_list":["post-795","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-lawn-ground-cover","tag-how-to-grow-sweet-potato-vine","tag-lawn-ground-cover","tag-sweet-potato-vine"],"_links":{"self":[{"href":"https:\/\/lifehacksmag.com\/garden\/wp-json\/wp\/v2\/posts\/795","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/lifehacksmag.com\/garden\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/lifehacksmag.com\/garden\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/lifehacksmag.com\/garden\/wp-json\/wp\/v2\/users\/6"}],"replies":[{"embeddable":true,"href":"https:\/\/lifehacksmag.com\/garden\/wp-json\/wp\/v2\/comments?post=795"}],"version-history":[{"count":1,"href":"https:\/\/lifehacksmag.com\/garden\/wp-json\/wp\/v2\/posts\/795\/revisions"}],"predecessor-version":[{"id":796,"href":"https:\/\/lifehacksmag.com\/garden\/wp-json\/wp\/v2\/posts\/795\/revisions\/796"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/lifehacksmag.com\/garden\/wp-json\/wp\/v2\/media\/2023"}],"wp:attachment":[{"href":"https:\/\/lifehacksmag.com\/garden\/wp-json\/wp\/v2\/media?parent=795"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/lifehacksmag.com\/garden\/wp-json\/wp\/v2\/categories?post=795"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/lifehacksmag.com\/garden\/wp-json\/wp\/v2\/tags?post=795"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}When to Plant Sweet Potato Vine<\/h2>\n
