cassava makes a cluster of four to eight swollen roots at the base of the stem. They are ready when they are plump and firm, usually after eight to nine months in warm ground. [1] A freeze before that date ends the crop, so lift ahead of cold weather this year, or save stems on Overwintering Cassava.

How long does cassava take to harvest?

Plan on eight to eleven frost-free months. Some early kinds are usable a little sooner; old roots left in the ground turn woody.

Cut the stem a foot up, then lift the roots without bruising them

  1. Cut the stem about one foot above the ground so you have a handle.
  2. Loosen the soil around and under the plant with a fork, staying clear of the roots. [2]
  3. Rock the stem gently, then pull upward so the cluster comes out in one piece.
  4. Cut or snap the roots from the stem. A typical root is about 1 to 4 inches thick and 8 to 15 inches long.
  5. Use the roots within a few days. Bruised roots blacken and spoil fast.

Do not eat the roots raw. Peel the thin reddish bark and cook them thoroughly. [3] The roots sit near the surface and run out from the stem, so a shallow test dig is enough to check size. [4]

How soon must I use harvested cassava?

Use it within a few days. Lifted roots spoil fast, so leave plants in the ground until you are ready to cook them.

Wait until a test root is plump, lift the cluster without cuts, and use it within a few days.

FAQ

Do I need a recipe to make cassava safe?

Peel the bark and cook the roots thoroughly, and throw out that cooking water. Do not eat them raw.
