Transcript
- 0:28Welcome back to the Beanstalk, fellow beans.
- 0:31My name is John, and today we're talking about one of the
- 0:34coziest, most comforting, most holiday centered crops in the
- 0:38entire garden. Sweet potatoes.
- 0:43These gems aren't just good for Thanksgiving though, let's be
- 0:47honest, that's where they shine in all their buttery,
- 0:50marshmallow topped glory. They're also one of the most
- 0:54rewarding, forgiving, and surprisingly tough crops you can
- 0:59grow. If you've ever wanted a plant
- 1:02that thrives on heat, shrugs off tough soil, and pays you back
- 1:07with pounds of food, sweet potatoes are your friend.
- 1:13So grab a warm drink, settle in, and let's dig into the world of
- 1:17sweet potatoes. From slips and soil temps all
- 1:21the way to that mashed sweet potato dish that absolutely
- 1:25belongs on every holiday table. Why should we grow sweet
- 1:30potatoes? Sweet potatoes are the kind of
- 1:34crops that gives more than it takes.
- 1:37If you're gardening in a warm summer climate, or even just a
- 1:40place with a halfway decent growing season, they reward you
- 1:44with big, beautiful tubers full of nutrients, color and flavor.
- 1:50They are heat lovers. Think July's sun as their happy
- 1:53place. They store naturally for months.
- 1:58A winter pantry hero. They're nutrient dense.
- 2:03They're a vitamin A powerhouse, and they're great space fillers.
- 2:09They're the vine that takes its career seriously.
- 2:13Plus, they're gorgeous. The vines alone could be
- 2:16ornamentals, and if you ever cured your own sweet potatoes
- 2:20and tasted them after the sugars develop, you know exactly why
- 2:24growing your own beats store bought every time.
- 2:28How to grow sweet potatoes Sweet potatoes don't start from seeds,
- 2:37they start from slips, those little shoots that come off of a
- 2:41mature tuber. You can buy slips, or you can
- 2:45make them yourself from an organic sweet potato with a
- 2:49little patience, warm water and a sunny window sill.
- 2:54Here's the quick garden friendly version, starting your slips.
- 3:02You can root the slips in water or directly in soil, but either
- 3:06way, let them grow until they have several leaves and a nice
- 3:10tuft of roots. When they're about 6 inches
- 3:13tall, they're ready for the big leagues, outdoors, soil and
- 3:19location. Sweet potatoes thrive in loose,
- 3:24warm, well drained soil. Think sandy loam if you've got
- 3:29it, or raised beds if you don't. If you garden in clay, get ahead
- 3:35of things by loosening the soil deep down or building up a mound
- 3:39or bed to give them room. They want full sun and they'll
- 3:44absolutely sprawl if you let them.
- 3:47So give them some space or let them become your living summer
- 3:50mulch planting. Wait until your soil is warm.
- 3:58Like really warm sweet potatoes want soil that feels like beach
- 4:02sand that's been sitting in the sun?
- 4:07Plant slips 12 to 18 inches apart, burying them deep enough
- 4:12that at least a few nodes leaf junctions end up in the
- 4:16underground. Water them well at first, then
- 4:22let the vines take off. How to harvest sweet potatoes
- 4:31Harvest time feels like a treasure dig about 90 to 120
- 4:35days after planting. Once the leaves yellow or that
- 4:40first light frost hits, it's time to dig carefully.
- 4:45Use a fork instead of a shovel so you don't stab the tubers.
- 4:49Sweet potatoes scratch easily, and scratches reduce their
- 4:52storage life. Curing.
- 4:59This is where the magic happens. Cure them at warm, humid
- 5:04temperatures for 7 to 14 days. This develops the sweetness and
- 5:10toughens the skin, so they'll store all winter.
- 5:15After curing, store them somewhere cool and dry and
- 5:18they're good for months. Common pests and problems Sweet
- 5:26potatoes are generally tough, but here are the usual suspects.
- 5:32Wireworms. They leave little holes in the
- 5:35tubers. Rotating crops and avoiding
- 5:39freshly broken sod helps. Deer and rabbits.
- 5:45They absolutely love the vines. A little fencing really goes a
- 5:50long way here. Weeds early on, the vines will
- 5:57eventually smother most competition, but keep the young
- 6:00plants weeded until they take off.
- 6:05Overall, they're one of the least fussy crops in the garden.
- 6:11Companion planting tips Sweet potatoes appreciate neighbors
- 6:18that help control pests or improve soil structure.
- 6:22Good companions include Bush beans, thyme, oregano and
- 6:29marigolds. Try to avoid planting them right
- 6:33next to squash or pumpkins. Those two will compete for space
- 6:38like siblings fighting over the last cookie seed saving tips, or
- 6:45rather slips. Sweet potatoes don't really
- 6:51produce garden friendly seeds. Instead, you save them by
- 6:56picking your best, healthiest tubers.
- 6:58At the end of the season, store a few of your nicest potatoes
- 7:03separately. These will become next year's
- 7:05slip producers come spring. Let them sprout indoors, snap
- 7:11off those slips and grow a whole new patch.
- 7:15It's a closed loop straight from your own garden.
- 7:21The pros and cons of sweet potatoes Firstly, the pros.
- 7:28They are incredibly productive, they have a great heat
- 7:32tolerance, they store all winter, the vines are beautiful
- 7:39and honestly you deal with very few pests with them.
- 7:45And now for the cons. Sweet potatoes need a long, warm
- 7:52season. Tough soil will equal funny
- 7:56shaped sweet potatoes, and vines can take over.
- 8:00If you're not watching, we've arrived at the recipe Honey
- 8:07glazed mashed sweet potatoes with Marshmallows.
- 8:13All right, this is where Thanksgiving really shows up.
- 8:17This recipe gives you that Mashed potato texture with the
- 8:20warm holiday sweetness everyone expects from sweet potatoes.
- 8:25It's nostalgic, delicious, and shockingly simple.
- 8:31The ingredients 4 to 5 medium sweet potatoes, 3 to 4
- 8:38tablespoons of butter, 2 to 3 tablespoons of honey, 1/4 cup of
- 8:46brown sugar, one tablespoon of vanilla, half a teaspoon of
- 8:54ginger, half a teaspoon of cinnamon, salt and pepper to
- 9:01taste, half a cup of milk or cream, and mini marshmallows.
- 9:09However many your heart says is right, here is the cooking
- 9:16directions. Peel, cube and boil your sweet
- 9:21potatoes until fork tender. Drain them and mash them while
- 9:27warm with your butter, honey, brown sugar, nutmeg, cinnamon,
- 9:34salt and pepper. After mixing, add the milk and
- 9:39marshmallows to make them extra creamy.
- 9:44Scoop into a casserole dish and spread evenly.
- 9:49Broil them for a few minutes, watching them closely.
- 9:53You're just trying to bring the flavors together and soften up
- 9:57the marshmallows. Serve warm and bask in applause.
- 10:04Some fun facts about sweet potatoes.
- 10:10Sweet potatoes aren't potatoes at all.
- 10:12They're closer to morning glories.
- 10:17Their leaves are edible and actually pretty tasty when
- 10:21sauteed. Purple sweet potatoes have more
- 10:26antioxidants than blueberries. In some cultures, sweet potatoes
- 10:33are considered a symbol of prosperity.
- 10:38And now for the garden nerd corner.
- 10:42Let's get nerdy for a second. Sweet potatoes develop sweetness
- 10:48from enzymatic starch to sugar conversion, which really ramps
- 10:53up during curing. That's why freshly dug sweet
- 10:56potatoes can taste almost bland, but after a week or two of
- 11:01curing? Totally different experience.
- 11:06Also fun? The pigments in purple sweet
- 11:09potatoes are anthocyanins, the same antioxidants found in red
- 11:15cabbage, berries, and black rice.
- 11:19They're basically superheroes in tuber form.
- 11:23Thanks again for hanging out with me on the Beanstalk.
- 11:27Sweet potatoes bring warmth, comfort, and a whole lot of
- 11:31flavor to the garden and the kitchen, and I hope this episode
- 11:35helps you grow your best crop yet and maybe even make a new
- 11:40family favorite Thanksgiving dish.
