Blue Flag

Blue Flag prefers for the soil to dry out between waterings and should be watered regularly. Use our water calculator to personalize watering recommendations to your environment or download Greg for more advanced recommendations for all of your plants.

Blue Flag 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 🏡.

Blue Flag is not safe to consume. 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. If you have children, cats, or dogs in the home, we suggest keeping this plant out of reach.

Blue Flag is very sensitive to dry soil, so choose a potting soil that retains moisture. A good soil will still drain well and contain lots of organic matter such as coco coir or sphagnum moss.

Blue Flag 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!

Blue Flag grows vertically and new growth will emerge from the top of the plant.

Blue Flag can be propagated by division into new individual plants.

• Check to see if there is more than one plant. In some cases they may still be beneath the soil surface. If you feel confident, you may remove the soil to check for baby plantlets below!
• If there are multiple plants growing, unpot the plant and gently tug the plants apart, being careful not to disturb too many of the roots. They may be connected by large root segments which you may need to break to free the plantlet.
• Pot up the new plant in well-draining soil
• Repot the parent plant back into its original pot
