What it is

Cassava (Yuca) (Manihot esculenta) is in the Euphorbiaceae (Spurge) family. A tropical calorie powerhouse for the Deep South — but the roots MUST be cooked properly to be safe.

How to grow it

It wants full sun, water it low — very drought-tough, and give it loose, sandy soil. Target a soil pH around 5.5–6.5. Space plants about 36 in apart. Expect roughly 240–300. Tender perennial; loves heat.

How it's used

Cassava (Yuca) is used: boiled, fried, flour (after processing).

🔎 How to identify it

  • Palmate hand-shaped leaves
  • Woody cane-like stems
  • Large starchy roots

CautionRaw cassava is toxic (cyanogenic) — peel and cook thoroughly. Bitter types need extra processing.
The grow guide

How to grow & propagate cassava (yuca)

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 cassava (yuca)

Cassava (Yuca) comes up from seed and, once it's a few years old, can be lifted and divided in cool weather to make more plants and keep the clump vigorous.

Growing cassava (yuca) in Texas

Give it full sun and loose, sandy 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 240–300 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: roots (always 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.

When the grid is down

Keep this knowledge offline

A garden full of cassava (yuca) 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.
