💡 FAQs
💦 Water Needs

☀️ Sunlight Needs

Caspian Onion requires abundant, bright and direct light. Place it less than one foot from a window to ensure it receives enough light to survive 💪. Select your region to see how the current weather in your area affects the placement in your home 🏡.


🐶 🐈 👶 Toxicity

Caspian Onion is extremely dangerous if consumed. If you, a family member, or a pet has ingested any amount of plant material contact Poison Control, US (800) 222-1222, or your veterinarian immediately. Caspian Onion is not recommended for homes with children, cats, or dogs.


💨 Humidity

Caspian Onion doesn’t require additional humidity. Plants absorb most water through their root system rather than their leaves, so the best way to provide humidity for your plants is through watering the soil.


🪴 Soil

Caspian Onion does best in well-draining soil. A good soil will contain lots of organic matter such as coco coir as well as perlite or vermiculite to help with drainage. Adding a handful of perlite to regular store-bought potting soil should do the trick!


💩 Fertilizer

Caspian Onion should be repotted after it doubles in size or once a year, whichever comes first. Fresh potting soil has all the nutrients your plant needs, so as long as it’s refreshed yearly, you shouldn’t need to use fertilizer. Remember, plants get their energy from sunlight, not fertilizer!


🌎 Native Region

Caspian Onion is native to the Northern Hemisphere, South America, and Africa.


🌦️ Growing Outdoors

🍂 Yellow Leaves

Yellow leaves aren’t always a reason to panic, and can be a normal part of a plant’s life cycle. Unless brand new leaves are turning yellow or all the leaves change color at once, it’s likely just your plant shedding old leaves.

Overwatering and root rot are the most likely cause of problems in Caspian Onion, since they are sensitive to wet soil. The leaves may also appear to be curling or drooping. Less often, yellow leaves are caused by underwatering, nutrient deficiencies, or pests.

Replace soggy soil with fresh, dry soil and download Greg to make sure your plant never gets overwatered again!


🧐 Troubleshooting

When troubleshooting a sad-looking houseplant, start by checking for signs of distress in its leaves, such as yellowing, browning, or drooping, which can indicate overwatering or nutrient deficiencies.

Inspect the soil moisture; too dry or too wet soil can cause problems.

Ensure the plant is getting the right amount of light, as too much or too little can stress it.

Finally, consider environmental factors like temperature and humidity, and adjust care routines accordingly to revive your plant.
