How to fertilize Blue Flag

Nutrient, fertilizer, and repotting needs for Blue Flag: repot after 2X growth

Most potting soils come with ample nutrients which plants use to produce new growth.

By the time your plant has depleted the nutrients in its soil it’s likely grown enough to need a larger pot anyway.

To replenish this plant's nutrients, repot your Blue Flag after it doubles in size or once a year—whichever comes first.

🐶 🐈 👶 Toxicity

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.


🪴 Soil

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.

💩 Fertilizer

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!

🌱 Propagation

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

🧐 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.
