About Ulluco
Ullucus tuberosus, commonly known as ulluco, is an Andean tuberous plant valued for its colorful edible tubers and compact foliage. Its trailing or semi-erect stems look great in vegetable gardens, large pots, or as part of a diverse edible landscape, adding a vibrant touch with its fleshy leaves and tubers that range in color from yellow to purple and pink. It's an excellent choice for those seeking nutritious and visually appealing root crops.

Care tips
Ulluco thrives in cool, humid climates, preferring full sun or light partial shade, especially in warmer regions. It requires well-drained soil rich in organic matter and slightly acidic to neutral, with regular watering to maintain consistent moisture without waterlogging. Avoid high temperatures, as they can inhibit tuber formation; be sure to protect it from extreme heat and frost. A common mistake is planting it in heavy, poorly drained soils, which can lead to tuber rot.
How to save a dying Ulluco

- What kills it
- Overwatering and poor drainage, causing tuber rot. Also extreme heat and prolonged drought.
- Can it be saved?
