Description
The tiger nut (Cyperus esculentus) is a sun-loving sedge from the Mediterranean that produces sweet, nut‑like underground tubers. In Spain these tubers are traditionally used to make Horchata de Chufa. The plant has narrow, reed‑like leaves and grows in a horchata‑like pattern on loose, sandy soil. In Central Europe the wild form is considered a persistent weed that spreads aggressively via its tubers, so it should be confined to a pot or a bed with a root barrier. The plant is harmless to children and pets; only its vigorous spread requires attention.
Care instructions
Plant the tubers from mid‑May (week 20) in a sunny, protected bed or, preferably, in a deep pot with a root barrier to prevent uncontrolled spread. Use loose, sandy, well‑draining soil; heavy, clay soils can be loosened with sand beforehand. Keep the soil evenly moist, especially in the first weeks after planting, but avoid waterlogging. Harvest begins in October when the foliage turns yellow; dig up the tubers carefully with a garden fork, preferably removing them completely to prevent unwanted sprouts the following year. Monitor the soil the next year and remove any remaining tubers to stop further spread.

Soil & site
Soil pH
Soil type
well-drained, sandy, moist, nutrient-rich
Tiger nut likes loose, sandy to sandy-loamy soil that lets water drain rather than hold it. It prefers even moisture, because the small tubers only form if the soil never dries out completely. Heavy, compacted soils slow the growth of the runners, so deep loosening is worthwhile before planting.
Feeding
Medium feeder
Months
May–Jul
Mature compost worked in before planting in spring is usually enough for tiger nut for the whole season. If the stand grows rather weakly, a dose of diluted nettle feed during the growing phase from May to July helps. It is better to avoid too much nitrogen, otherwise mainly the foliage grows instead of the tubers.
Overwintering
In Central Europe, tiger nut does not reliably survive winter outdoors, so the tubers are harvested completely in autumn. Store part of the harvest dry and cool until spring, and you will have the planting stock for the next season ready. In mild, sheltered locations, some of the tubers may survive in the soil and sprout again in spring.
Propagation
Methods
- Offsets
You propagate tiger nut by the small tubers that form underground on the roots. From mid-May · week 20, when frosts no longer threaten, push the tubers about 3 to 5 cm deep into loose soil. Keep the soil evenly moist until shoots appear, and the first grass-like shoots will show after a few weeks. From the autumn harvest, choose strong, plump tubers for the next planting.
