Allium obtusum aka Red Sierra Onion

Red Sierra Onion should be watered regularly, allowing the soil to dry out between waterings.

Red Sierra Onion loves a well-draining soil. Perlite and vermiculite help with drainage, while coco coir adds organic matter, so a good potting soil mix will have all three. You can improve store-bought soil by adding some perlite to it.

Red Sierra Onion requires abundant, bright, and direct light to thrive. The best placement for this plant is within one foot of a window to ensure it receives enough light. If you live in an area with more extreme weather, such as hot summers or cold winters, you may need to adjust the placement of the plant accordingly. During hot summer months, it is important to place the plant away from full sun, as this can cause the leaves to yellow or burn. During cold winter months, it is best to move the plant closer to the window to take advantage of the extra light that can help it survive. By keeping an eye on the current weather in your area, you can make sure your Red Sierra Onion is always in the right place to thrive.

No verified data on the toxicity of this plant exists within Ploi's records. Should you, someone in your family, or your pet ingest plant material with an unknown toxicity level, it is recommended to seek medical advice.

The Red Sierra Onion does not demand additional humidity levels. Water is mostly absorbed by the roots of plants, rather than their leaves, and the best way to provide humidity to your plants is through watering the soil.

Once the Red Sierra Onion has doubled in size or after a year has passed, it should be moved to a new pot. By replacing the soil with fresh potting soil containing all the vital nutrients, your plant will receive all the sustenance it needs, negating the requirement for fertilizer. It's important to remember that plants get their energy from the sun, not fertilizer.

New growth will sprout from the top of the Red Sierra Onion as it grows vertically.

Red Sierra Onion’s native range is the Northern Hemisphere, South America, and Africa.
