How to fertilize Crimsoneyed Rosemallow

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 Crimsoneyed Rosemallow after it doubles in size or once a year—whichever comes first.

My partner's grandma gave me a potted cutting of her hibiscus (which is 20+ years old apparently) about a month ago, and the past week or two it is TAKING OFF with a bunch of brand new leaves. I'm so pleased! 😊 #HappyPlants #PlantsMakePeopleHappy #Hibiscus

Y’all my app said to water Lulu today and she’s been doing good on this schedule. This morning she was droopy and not thirty minutes ago I gave her some water and WOW at how fast this child perked up lol. All her leaves are sticking straight up now. It’s like she fell asleep in class, the teacher called her name, and she’s trying to act like she wasn’t snoozing 🤣🌺🤭🫣 #Hibiscus #HappyPlants #Funny #wakeup #classclown

💦 Water Needs
Crimsoneyed Rosemallow 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.
☀️ Sunlight Needs
Crimsoneyed Rosemallow 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
Greg does not have confirmed data on this plant’s toxicity. If you, a family member, or a pet consumes plant material of unknown toxicity, it’s always best to consult a medical professional.
If you or someone else ingested this plant, call Poison Control at US (800) 222-1222. If a pet consumed this plant, contact your veterinarian or the ASPCA at US (888) 426-4435.
💨 Humidity
Crimsoneyed Rosemallow 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
Crimsoneyed Rosemallow 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
Crimsoneyed Rosemallow 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
Crimsoneyed Rosemallow 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.
