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 Iron Cross after it doubles in size or once a year—whichever comes first.

I grew this from 2 bulbs but only one of them has come up. Should i give up hope on the other one or do you think it will come up as well? #PurpleShamrocks

Prince has been having a rough time growing. It seems to grow for a few days then drie out. It's a continuous cycle. Is this normal cause it doesn't feel normal?

Hi there! I have an iron cross shamrock that is drooping pretty low and some of the leaves browned a little bit ago. It's been OK since then but still droopy. Some things make it seem like this is normal but before they were standing up. They still "open" during the day and I keep it right by the window. Anything I can do for it? Most of my plants are thriving but this one is very different so can't seem to figure out a solution.

Just a quick shot from this morning of my purple shamrocks basking in sunlight. So simple, yet so beautiful… #HappyPlants #PlantsMakePeopleHappy #PlantAddict #PlantTherapy #Oxalis #PurpleShamrocks

This is the purple shamrock I’ve had for a little over a month. The picture on the left is from the day I brought him home, and the other shot is from a few days ago. In that time, El Morado has at least doubled in size!!! What? Who knew Oxalis grew so quickly and required so little? What a great plant to add to your collection! 😍 #HappyPlants #PlantsMakePeopleHappy #PlantAddict #PlantTherapy #BeforeAndAfter #PurpleShamrocks #Oxalis #gottacatchemall #PlantLove

Currently checking all my plants but i need to know soon so i can help her before i head to work this week . Im 99 percent sure it is mold ( idk how considering i bottom water and i wait until the top is dry to water again) but i have no idea what to do and now do i keep my other plants safe #sickplants #Fungi #planthelp #WhatsWrongWithMyPlant #GregGang #PlantsMakePeopleHappy

shamrock update! so I have determined due to the fact that I noticed a lot of it on my other plants that are healthy and actually thriving that what is on my shamrock plant is actually mineral deposit however she is still doing very bad in comparison and she’s actually getting worse by the day. Does anyone have any tips dealing with hard water? Is there anyway I can flush it out of her system without overring or having to repot? #planthelp #sickplants #PlantAddict #RarePlants . Unfortunately I have work for the rest of the weekend so any outside care I probably won’t be able to provide for her.

Please help. What does my little plant need? The leaves are starting to brown on the ends. #PurpleShamrocks

Iron Cross 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.
Iron Cross 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 🏡.
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 atUS (888) 426-4435.
Iron Cross 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.
Iron Cross 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!
Iron Cross grows very slowly and doesn’t require added fertilizer. Replacing your plant’s potting soil once a year should provide them with more than enough nutrition. Remember, plants get their energy from sunlight, not fertilizer!
Iron Cross is native to Worldwide.
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.
