Cebolla Patata
Allium cepa var. aggregatum
De un vistazo
Allium cepa var. aggregatum, conocida como cebolla patata o cebolla multiplicadora, es una variedad perenne que se reproduce vegetativamente formando racimos de bulbos subterráneos de manera similar a como las patatas producen tubérculos. Es una hortaliza tradicional europea cultivada durante siglos por su facilidad de propagación y excelente sabor suave.

Etapas de crecimiento
De la semilla a la cosecha
Plantación
Las cebollas de patata se plantan como bulbos, no como semillas. Los bulbos pequeños se colocan a 5 cm de profundidad y a 20 cm de distancia a comienzos de la primavera, o en otoño para pasar el invierno. Cada bulbo emite raíces rápidamente y, según la temperatura del suelo, un brote verde aparece en 7-14 días.
💡 Consejo de cuidado
Elige bulbos firmes y libres de enfermedades para plantar. Los bulbos pequeños producen los mayores grupos de bulbillos hijuelos, mientras que los bulbos más grandes suelen producir menos, pero individuales más grandes. Planta con la punta hacia arriba en un suelo bien drenado y enriquecido con compost.
Plant bulbs 10-15 cm apart and 5 cm deep in early spring as soon as the soil can be worked

Datos fascinantes sobre Cebolla Patata
Potato onions get their name not from any relation to potatoes but from the way they multiply underground — a single planted bulb divides into a cluster of new bulbs, much like a potato produces multiple tubers from a single seed potato.
La cebolla patata se cultiva exclusivamente a partir de bulbos, ya que rara vez produce semillas viables. Plante los bulbos en otoño o a principios de primavera, enterrándolos con la punta hacia arriba a una profundidad de 3-5 cm y con una separación de 20-25 cm. Los bulbos grandes producen más divisiones de menor tamaño, mientras que los pequeños generan menos bulbos pero más grandes.
Proporcione un lugar con pleno sol y riego moderado, manteniendo el suelo húmedo pero nunca encharcado. Aplique un acolchado orgánico alrededor de las plantas para conservar humedad, suprimir malezas y regular la temperatura del suelo. Evite el riego excesivo cuando los bulbos comienzan a madurar.
Cada bulbo plantado se dividirá en un racimo de 3 a 12 bulbos nuevos durante la temporada de crecimiento. Reserve siempre los bulbos de tamaño mediano de cada cosecha para replantar en la siguiente temporada, estableciendo un ciclo de producción autosostenible que no requiere comprar material de plantación año tras año.
Potato onions thrive in raised beds with good drainage and a thick layer of organic mulch
The potato onion (Allium cepa var. aggregatum) is an ancient multiplier onion whose precise origins are debated among historians, but most evidence points to Central or Western Asia as its ancestral homeland, in the same broad region where the common onion (Allium cepa) was first domesticated thousands of years ago. Unlike seed-propagated onions, potato onions have been passed from gardener to gardener as bulbs for so many centuries that their exact wild ancestor is no longer identifiable.
Potato onions were widely cultivated across Europe by the medieval period, with documented use in France, Britain, and Scandinavia by the 1600s. They became the dominant garden onion in Northern Europe and Colonial America for a simple reason: they were far easier and more reliable to grow than seed onions. In an era before modern seed production and hybrid vigor, growing onions from seed was slow, unreliable, and required significant skill. Potato onions, by contrast, could be planted as bulbs by any gardener, grew vigorously, produced a reliable harvest, and stored through the entire winter — making them indispensable for household food security.
By the 19th century, potato onions were standard fare in American and European kitchen gardens. They appear in the garden records of Thomas Jefferson at Monticello and were cataloged by numerous seed houses. However, the rise of commercial onion seed production, modern hybrid varieties, and industrial agriculture in the early 20th century gradually displaced potato onions from mainstream cultivation. Commercial growers preferred seed-grown onions for their uniformity and the economic model of annual seed sales.
Today, potato onions are experiencing a significant revival among heirloom vegetable enthusiasts, permaculture practitioners, and self-sufficiency gardeners worldwide. Their extraordinary storage life, self-perpetuating nature, cold hardiness, and rich flavor have earned them renewed appreciation. Small-scale seed companies and heritage seed exchanges in North America, Europe, and Scandinavia now offer multiple strains including yellow, red, and white varieties, ensuring the survival of this ancient and remarkably practical allium for future generations.
La cebolla patata se propaga exclusivamente por división de bulbos, no por semillas. Plante los bulbos en otoño para cosecha de verano o a principios de primavera tan pronto como el suelo sea trabajable. Seleccione bulbos sanos de tamaño mediano (2-3 cm) para obtener el mejor equilibrio entre número y tamaño de los bulbos producidos.
La cebolla patata prefiere suelos francos, bien drenados y moderadamente fértiles, con un pH entre 6,0 y 7,0. Incorpore compost maduro antes de la plantación y evite el exceso de nitrógeno que promueve crecimiento foliar a expensas de los bulbos. Aplique un fertilizante rico en fósforo y potasio al inicio del engrosamiento de los bulbos.

10°C – 24°C
50°F – 75°F
Potato onions grow best in cool to moderate temperatures of 10-24°C (50-75°F). They are remarkably cold-hardy — autumn-planted bulbs survive winters down to -30°C (-22°F) under mulch, and spring growth resumes as soon as soil thaws. Bulb formation is triggered by long days (14+ hours) combined with warm temperatures. Prolonged heat above 30°C (86°F) can cause premature dormancy and smaller bulbs. The ideal growing season pairs cool, moist springs for leaf development with warm, dry summers for bulb maturation and curing.
Problemas comunes que afectan a Cebolla Patata y cómo prevenirlos y tratarlos de forma orgánica.
La cebolla patata puede multiplicarse de forma tan vigorosa que los racimos se congestionan, produciendo bulbos cada vez más pequeños si no se dividen y replantan regularmente. La disponibilidad de material de plantación puede ser difícil ya que no se encuentra fácilmente en comercios convencionales. En climas muy cálidos, los bulbos pueden no recibir suficiente frío invernal para romper la dormancia.
La cebolla patata es excelente compañera para zanahorias, ya que su aroma repele a la mosca de la zanahoria mientras que las zanahorias ahuyentan a la mosca de la cebolla. Se asocia bien con repollo, lechuga y fresas. Evite plantar cerca de leguminosas como guisantes y frijoles, ya que las cebollas pueden inhibir su crecimiento.
- 1Plant small bulbs to get many bulbs, plant large bulbs to get large bulbs. This is the fundamental rule of potato onions. Small planting stock (2-3 cm) divides into clusters of 5-12 smaller bulbs, while large planting stock (5-7 cm) produces fewer but significantly bigger individual bulbs. Use this to your advantage depending on whether you want volume or size.
- 2Autumn planting produces superior results in most climates. Bulbs planted in September-October establish roots before winter, break dormancy earlier in spring, and produce harvests 3-4 weeks ahead of spring-planted bulbs with noticeably larger yields. Mulch heavily after the ground freezes to protect from heaving.
- 3Drainage is the single most critical soil factor. Potato onions will tolerate a wide range of soil types and fertility levels, but they will not survive waterlogged conditions. Raised beds are ideal in heavy clay soils. If your soil holds water after rain, plant on mounds or in containers.
- 4Do not over-fertilize. Potato onions are moderate feeders that perform well in average garden soil amended with compost. Excessive nitrogen produces lush tops but delays bulb formation and reduces storage life. One application of balanced fertilizer at planting and one side-dressing in mid-spring is sufficient.
- 5Save your own planting stock religiously. After each harvest, immediately set aside the best small bulbs for replanting. Store them in a cool, dry place separate from your eating onions. This practice, repeated annually, gradually selects a strain perfectly adapted to your specific garden conditions.
- 6Weed early and often. Onions have shallow, sparse root systems and cannot compete with weeds. A thick mulch of straw or shredded leaves applied after planting dramatically reduces weeding labor and conserves the consistent moisture that potato onions need during their leaf-growth phase.
- 7Resist the urge to water during the final maturation phase. Once tops begin to yellow and fall over, the bulbs are curing in the ground. Additional water at this stage promotes neck rot and drastically shortens storage life. If rain threatens during curing, consider lifting the bulbs early.
- 8Cure thoroughly before storing. Inadequate curing is the number one cause of storage failures. Bulbs need 2-3 weeks in a warm (24-30°C), dry, well-ventilated location until the outer skins are fully papery, the necks are completely sealed, and the roots are dry and brittle.
Coseche cuando las hojas se amarilleen y se tumben naturalmente, generalmente entre 90 y 120 días después de la plantación primaveral. Levante los racimos de bulbos cuidadosamente con una horca de jardín para evitar dañarlos. Deje los bulbos secar al sol durante varios días hasta que las capas exteriores estén secas y crujientes.
Harvested clusters curing in warm sun — allow 2-3 weeks of drying before storage
Los bulbos curados se almacenan en un lugar fresco, seco y bien ventilado, idealmente entre 5 y 10°C, donde pueden conservarse durante 6-10 meses. Guárdelos en redes, cestas o trenzados que permitan la circulación de aire. Inspeccione regularmente y retire cualquier bulbo con signos de pudrición. Reserve los bulbos medianos para replantación.

💰 ¿Por qué cultivar tus propios?
Potato onions are the ultimate self-sustaining vegetable investment. An initial purchase of 10-15 bulbs ($10-20 from a heritage seed company) becomes a permanent, self-renewing onion supply that never requires buying seed or sets again. Each year's harvest provides both eating onions and planting stock for the following year. With 20-30 plants producing 4-8 kg of onions annually and specialty shallot-type onions selling for $4-8 per pound at farmers markets, your perpetual patch saves $40-100 per year indefinitely. Factor in the exceptional 8-12 month storage life that eliminates waste, and potato onions may be the most cost-effective vegetable a gardener can grow over a lifetime.

What is the difference between potato onions and shallots?
Potato onions and shallots are both multiplier onions in the Allium cepa aggregatum group, and they are closely related. The main differences are size and growth habit: potato onions produce larger bulbs (often 5-8 cm diameter) in clusters of 3-12, while true shallots tend to be smaller and more elongated. Potato onions also generally store longer and are more cold-hardy. Some horticultural references treat potato onions as a type of large shallot, and the distinction is not always clear-cut. In the kitchen, potato onions have a similarly rich, sweet flavor but with more substance per bulb.
Can I grow potato onions from seed?
Potato onions rarely produce seed because they have been propagated vegetatively (by bulb division) for so many centuries that most strains have lost the ability to flower reliably. On rare occasions, a plant may bolt and produce a flower stalk, but the resulting seed is often infertile or produces highly variable offspring. The standard and most reliable method is to plant saved bulbs from the previous year's harvest — this is the traditional propagation method that has sustained potato onion cultivation for centuries.
How long do potato onions store?
Properly cured potato onions are among the longest-storing alliums available. Bulbs cured for 2-3 weeks and stored at 10-15°C (50-60°F) in a dry location with good airflow routinely last 8-12 months. Some growers report storage of 14 months or more under ideal conditions. The key factors are thorough curing, dry necks, intact papery skins, cool and consistent temperature, low humidity, and good ventilation. Store in mesh bags, open crates, or braided by their stems — never in sealed plastic bags.
Why did my potato onions bolt instead of forming bulbs?
Bolting (sending up a flower stalk) in potato onions is triggered by prolonged cold exposure followed by warming temperatures — essentially, the bulb goes through a vernalization period that tells it to reproduce by seed rather than division. This most commonly happens with large autumn-planted bulbs that experience an extended cold winter. To reduce bolting, plant smaller bulbs in autumn (they are less prone to vernalization) or delay planting large bulbs until spring. If a flower stalk appears, snap it off immediately to redirect energy back into bulb development.
How many potato onions should I plant to feed a family?
For a family of four that uses onions regularly in cooking, plant 30-50 bulbs to produce roughly 6-12 kg of onions. This provides enough for year-round use while reserving 15-20 small bulbs for replanting the following year. Start with at least 15-20 bulbs in your first year to establish a self-sustaining cycle. Within 2-3 years of saving and replanting your own stock, you will have more than enough bulbs to be completely self-sufficient in onions.
Can I plant potato onions bought from the grocery store?
Grocery store shallots or multiplier onions can sometimes work as starting stock, but results are unpredictable. They may have been treated with sprout inhibitors, could carry diseases, and may not be adapted to your climate. For best results, purchase certified disease-free planting stock from a reputable heritage seed company or obtain bulbs from a fellow gardener with a healthy, productive strain. The small initial investment pays off permanently since you will never need to buy onion planting stock again.
