What it is
Sweet Potato (Ipomoea batatas) is in the Convolvulaceae (Morning Glory) family. One of the best survival calories for the Deep South — heat-loving, drought-tough, and the leaves are edible too.
How to grow it
It wants full sun, water it low once established, and give it loose, sandy preferred soil. Target a soil pH around 5.5–6.5. Space plants about 12–18 in apart. Expect roughly 90–120. Warm-season; loves Texas heat.
How it's used
Sweet Potato is used: roasted, mashed, stored; leaves cooked.
🔎 How to identify it
- Heart-shaped or lobed vine leaves
- Trailing ground vines
- Morning-glory-type flowers

How to grow & propagate sweet potato
Everything I've worked out about starting this one, keeping it alive through a Texas year, and turning one plant into many — free.
How to propagate sweet potato
Sweet potatoes grow from 'slips' — leafy shoots you sprout off a stored tuber. Set a sweet potato half-buried in damp sand or suspended in water, and in a few weeks it pushes out shoots you snap off and root. Each tuber gives you a dozen or more new plants.
Growing sweet potato in Texas
Give it full sun and loose, sandy preferred soil. Match the spot to the plant and most of the battle is already won.
This one thrives in heat that flattens other plants, so it earns its space through a Texas summer. Get it established before the worst of July, keep water steady, and it'll produce when little else will.
Once it's rooted in, this is a low-water plant — overwatering does more harm than drought here. Water deeply to establish, then back off and let it prove how tough it is.
Harvesting
Figure on roughly 90–120 before you're harvesting. Harvest at peak and keep harvesting — most vegetables produce harder the more you pick, and one left to over-mature tells the plant its job is done. The part you're after: tubers and young leaves.
Making more for free
Save it the easy way — vegetatively. Because you can clone this plant from a cutting, division, or piece of root, you never have to buy it again: keep one healthy mother plant and make all the copies you want.
Keep this knowledge offline
A garden full of sweet potato is a real asset when times get hard — but the know-how to grow, store, and use it shouldn't live only on a website you can't reach. That's why I keep a copy of the references I rely on on a local server at home. Project NOMAD is a free, open-source way to run Wikipedia, survival and medical guides, maps, and even a private AI on your own hardware — knowledge that keeps working with no internet, no cloud, no signal.
