What it is
Potato (Solanum tuberosum) is in the Solanaceae (Nightshade) family. Serious storable calories from a small space. Hill soil over the stems to grow more tubers.
How to grow it
It wants full sun, water it even — critical at tubering, and give it loose, slightly acidic soil. Target a soil pH around 5.0–6.0. Space plants about 12 in apart. Expect roughly 70–120. Cool-season.
How it's used
Potato is used: boiled, roasted, mashed, stored.
🔎 How to identify it
- Compound leaves like tomato
- White/purple star flowers
- Tubers form on underground stems

How to grow & propagate 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 potato
Tomatoes, peppers, eggplant and their cousins are warm-season crops started inside 6–8 weeks before your last frost, then transplanted out once nights stay above 50°F. Tomatoes are the exception to most rules — you can bury the stem deep or root a side shoot (a 'sucker') in water to clone a plant mid-season. Potatoes skip seed entirely and grow from seed potatoes — chunks of tuber with an eye or two.
Growing potato in Texas
Give it full sun and loose, slightly acidic soil. Match the spot to the plant and most of the battle is already won.
Time your planting to our long warm season and watch the frost dates at both ends; the live weather tool on this site is built for exactly that.
Keep moisture even, especially while it's young — deep, less-frequent soaks build better roots than a daily sprinkle.
Harvesting
Figure on roughly 70–120 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 (cooked).
Making more for free
Every seed we sell is open-pollinated, which means you can save your own from the best plants and it'll grow true next year. Let a few of your strongest plants finish and go to seed, dry it fully, and store it cool and dark. That's the whole point of heirlooms — buy once, grow forever.
Keep this knowledge offline
A garden full of 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.
