How to fertilize Oxalis Triangularis

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 Oxalis Triangularis after it doubles in size or once a year—whichever comes first.

Oxalis Triangularis is generally easy to care for, though some plant parents report facing challenges with growing it. Check out the reviews down below to read more about their experiences!
Water Needs
Oxalis Triangularis 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
Oxalis Triangularis 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
Oxalis Triangularis 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.
Humidity
Oxalis Triangularis 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
Oxalis Triangularis 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
Oxalis Triangularis 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!
Native Region
Oxalis Triangularis is native to Worldwide.
Flowers
Yes, you may see your Oxalis Triangularis bloom with the right amount of sunlight and water.
Growth Pattern
Oxalis Triangularis is a clumping plant, meaning new growth will emerge from the soil around the parent plant.
Growing Outdoors
USDA Hardiness Zone
Oxalis Triangularis can be grown outdoors in USDA Hardiness Zones 8a-11b. Find your local hardiness zone here.
Propagation
Oxalis Triangularis 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
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 Oxalis Triangularis, 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!

What other plant parents say












I love my shamrocks! They are a bulb plant and bloom extremely easy. I have new sprouts about every week, a flower once month. We are now getting into the colder months and it still is not dormant! If you decided to give them a "rain bath" the leaves can brown/break, so be careful!








I love waking up and going to see my butterflies. They are so happy, fully open and ready for the day. It’s just an overall fun plant. The butterflies range in color for me. Some are a deep purple, others are a dark lime green and some are even a mixture of both but faded as if bleached. The flowers are absolutely adorable and also open and close at night.







One of the first plants I purchased back in 2019. Still going strong almost 2 years later! I have propagated this plant a couple times and given the babies as a gift to other family members once they were ready to set out on their own! It’s a strong, stubborn little thing!
