- Place the plant in a location that is at room temperature, has sufficient airflow, and receives bright but indirect light.
- Keep the soil just slightly damp. Use little water and let the soil dry up in between applications.
- Every few months, fertilize indoor plants with a balanced fertilizer.
- The plant is signaling to you that it needs a period of dormancy to rest when its leaves start to die back in late spring or early summer. Do not water or fertilize the plant at this time; instead, relocate it to a cooler, darker area away from direct sun. Depending on the cultivar and the environment, the dormant phase might extend anywhere from a few weeks and three months.
- Check your plant for new growth every week or so after the first few weeks of dormancy.
- The time of dormancy is over once new shoots start to develop. Relocate the plant to a more sunny spot and carry on with the suggested routine plant maintenance.
A shamrock plant after St. Patrick’s Day—have you ever kept one? Comment with your shamrock plant care advice!
How often should a shamrock plant be watered?
Planting shamrock bulbs in the fall or early spring results in the growth of shamrock plants. Shamrock plants are often bought when their foliage is growing, albeit occasionally when they are in bloom. There are numerous oxalis cultivars, but exotic species perform best indoors. Don’t expect to cultivate a wild wood sorrel indoors by digging it up from the outside, though.
Include a shamrock plant in your indoor collection for winter blossoms and perhaps good luck now that you know what it is and how to care for a flourishing Oxalis houseplant.
My shamrock plant is withering; why?
Most of the time, when a shamrock plant looks to be withering, all it really needs is a rest period or an off-season. It is a perennial plant that grows from a bulb, so if it starts to wither at the end of one growth season, just trim off the affected areas and wait for the new growing season to begin.
What is the lifespan of a shamrock plant?
You’re welcome to take your shamrock on a summer vacation outside in a shaded area. According to Michigan State University Extension, you can either leave it in its pot or plant it in front of a shaded border. Dig up the plant before it freezes and repot it so you can enjoy it as a houseplant all winter. Shamrock plants can remain outside all year in warm regions (USDA Hardiness Zone 8 and warmer).
How much sun is required by shamrock plants?
Shamrocks thrive in full sun, however they can also take some shade.
However, as they are dormant during the winter, shamrocks prefer to be kept on the dry side.
They should be grown in raised planting beds or under the eaves of the house in regions with wet winters.
How simple are shamrock plants to maintain?
The Shamrock Plant is a beloved gift plant for St. Patrick’s Day due to its resemblance to four leaf clovers.
These St. Patrick’s Day shamrocks could be seen as “lucky” because they are simple to grow. Shamrock care is simple because these perennial plants do well in typical indoor environments.
Did you know…
Because it belongs to the Wood Sorrell family, oxalis is not a real clover. This plant derives its reputation as being “lucky” from four leaf clovers due to similarities in appearance.
Shamrock plants are wonderful indoor plants. Shamrocks have an invasive character when grown outside. They can spread like wildfire due to their rapidly proliferating tuberous roots. However, you may grow this plant in a container and place it on your windowsill to get a close-up look at its lovely, clover-like leaves and tiny blooms.
Can shamrocks be grown indoors?
Shamrocks are a seasonal houseplant that are sold at florist shops, garden centers, and other stores for a brief period of time. While many seasonal plants are thrown away once they bloom, with the right care, shamrocks can last for many years as houseplants.
Shamrock and clover are two common names for plants that actually relate to a variety of distinct species of plants. Although practically any plant with three leaflets or trifoliate leaves can be referred to as a shamrock or clover, Trifolium and Oxalis plants are the most usually referred to as shamrocks. White clover, a popular lawn weed, and cover crops like red and common clover are among the plant species in the genus Trifolium. A plant species from the genus Oxalis is known as the common indoor shamrock. The shamrocks used as houseplants are not winter-hardy outdoors in Iowa, even though there are species of Oxalis endemic to the state (also known as sorrel).
For their enormous, green or purple foliage and 3-leaflet leaves, oxalis as shamrocks are planted. They are not commonly grown for their blooms, but when grown in ideal conditions and given proper care, they frequently yield delicate white, lavender, pink, or even yellow flowers. Some species have the intriguing trait of closing their leaves and/or flowers at night, only to reopen them the following morning.
Shamrocks have shallow root systems and grow from modified stems or tubers. They do best when kept “pot bound” and prefer slightly wet, well-drained soils. In areas with cool nighttime temperatures (about 60F) and high daytime temperatures, they like strong, indirect light (around 70F). During the growing season and after flowering, plants are frequently given a little fertilization with a diluted fertilizer solution once or twice a month.
Some Oxalis species need to relax or go dormant. The leaves of plants frequently turn yellow and die as they go into hibernation. High temperatures in the late summer or shorter days/colder nights in the fall may cause this. Plants should be kept dark, cool, and generally dry until new growth starts because dormancy usually lasts for 1-3 months. Plants can be sparingly watered as new growth appears and placed in bright, indirect light for optimal leaf development. Plants frequently develop blooms when they have enough of light.
Shamrocks come in a variety of species and cultivars and are popular around St. Patrick’s Day. Even an Oxalis species known as Lucky Shamrock has more 4-leaflet leaves than 3-leaflets. Good fortune!
Soil Requirements for oxalis
Ideal soil has good drainage and is somewhat acidic. (Sprinkling nearby with coffee grounds can assist to reduce the soil’s acidity.)
It will be advantageous to use a lot of compost or organic waste before planting the bulbs.
Sunlight needs for shamrock plants
If the plant receives a few hours of sunlight each day, it will grow the healthiest. A shaded afternoon is great. Some are growing in my sunny garden, while others are in the shade, and the ones in the shadow seem to do best.
Oxalis leaves may wilt slightly in the afternoon sun, but they soon bounce back as the day cools off.
Compared to plants with green leaves, those with the darker purple foliage thrive in environments with less sunshine.
Watering and fertilizer needs of oxalis
Oxalis like moist soil with good drainage, however it does not like to remain in a wet area. Avoid overwatering since too much moisture in the soil may cause bulbs to easily decay.
During the growing season, fertilize often with a typical plant food diluted to half strength.
How to propagate oxalis
By removing and dividing the clumps of bulbs under the soil, you can get extra plants for nothing. The majority of oxalis plants maintain a reasonably compact size and are unlikely to require frequent division in the garden.
Once you have a few plants growing, they will spread since the plants also self-seed. (This could be an issue if the garden beds have no edging and the most invasive species flourish there, spreading to your lawn.)
Cold hardiness for oxalis
In zones 6 and warmer, certain plant kinds can withstand cold temperatures. However, it depends on the kind. Many kinds are handled as annuals since they are frost-sensitive and won’t survive the winter.
Dig the bulbs up, nurture them as indoor plants for the winter, and then replant them in the spring to overwinter oxalis.
Growing oxalis indoors
Indoor oxalis plant maintenance is also simple. Just be cautious around water and give it plenty of sunlight.
This perennial can be cultivated indoors or outdoors, but it prefers a shaded location. If possible, grow oxalis indoors in a room with cold temperatures and bright light. (The optimal range is between 60 and 70 degrees.)
The darker the foliage is, the more light the plant receives, yet too much sunlight will “bleach out” the leaves. During the months when your indoor plants are growing, give them a regular feeding.
What does an Oxalis that is too wet look like?
Oxalis triangularis, a stunning plant that resembles a butterfly, is also known as false shamrock. The original country of this beautiful, energetic plant is Brazil. Although this plant appears to be delicate and difficult to maintain, the reverse is actually true. If given the right care, this plant is truly so resilient that it has been reported to survive for generations. It produces beautiful tiny flowers and is one of the few flowering indoor plants.
Light:
Oxalis adore direct, bright sunlight. They enjoy getting some early morning sun. When placed indoors, place it near a door or window that receives brilliant indirect light all day long in addition to morning direct sunlight. They shouldn’t be exposed to the sun for longer than two hours at a time because too much sun can harm them. Try to put them where there is lots of light because they do love the terrace/balcony lights here in Puerto Rico.
Water:
Because it is particularly prone to root rot, it is crucial to allow the soil dry out in between waterings. However, don’t let it dry out too much. Oxalis will experience a dormant phase that makes it appear as though they didn’t make it if they are overwatered or given insufficient water. When the soil is dry, the leaves have not fully opened, and the lighting is favorable, it is time to water the plant. It may indicate overwatering if leaves begin to feel mushy, fail to open, or develop strange, dark-looking patches. Stop watering if the plant has been overwatered, let it dry completely, and give it time to recover.
Soil:
Oxalis require a potting soil that drains properly. We advise using an indoor potting mix that contains peat moss, perlite, or vermiculite; alternatively, you can make your own mix by mixing half peat moss and half perlite. Without decomposing the roots, this mixture aids in moisture retention. Additionally, sand or Orchid bark added to the mixture will aid with drainage.
Food:
For the following few months, you can add a balanced slow-release fertilizer and completely ignore it. You can fertilize every two weeks or once a month if you prefer to use fertilizer that has been diluted in water. Continually abide by the fertilizer’s instructions.
Repotting:
To give it more room to grow, repot it once every other year. Use only pots that have holes for drainage. Repot in a container that is 1 bigger in height and diameter. They don’t require a lot of room to grow; they may also do so in compact areas. Every two years, it’s also a good idea to switch up the potting soil, but be careful around the bulbs and root system because they can be delicate.
Propagation:
The greatest and quickest way to multiply Oxalis is through their bulbs, therefore be extremely careful when planting this adorable youngster.
Toxicity:
Large doses of oxalis triangularis are poisonous to people, dogs, and cats. When ingested by animals, it might result in lethargy, drooling, vomiting, and diarrhea.
Facts:
- A decorative edible is oxalis triangularis (can only be consumed in small quantities). It has a pleasant flavor.
- They blossom into little pink blooms.
- Light causes the leaves of oxalis to move. It’s typical for them to do this at night when there isn’t enough light, then they reopen in the morning.
- I can say this from experience: LEAVE THEM BE. Let plants be, as we constantly advise. Don’t focus too much on them. Too much water typically implies attention. Root rot is a result of too much water.
- If your Oxalis appears to be “dead,” it may be inactive as they occasionally go through a period of hibernation. When this occurs as a result of overwatering, it is crucial to fully cease watering, let the area to dry, and then begin watering again once new leaves begin to grow.
How come my shamrock is sagging?
Despite no changes in care, if your Oxalis triangularis starts to look a little ragged, it may be naturally entering its dormant stage.
You shouldn’t be concerned because it is not dying! Consider it an opportunity to revive your plant. You’ll just have to get used to the dormant time because it’s typical.
Every year, sometime after the main growing season, your Oxalis could begin to appear a little slack. During the day, the leaves may stop opening up.
It’s time to relax your triangularis at this moment. At this stage, I advise ceasing to water and allowing the leaves to totally dry out. After that, remove the leaves, put it somewhere cool and dark (above freezing), and let it rest for 3–4 weeks, or even up to 6 weeks. During this time, avoid watering.
Bring your plant out of hibernation after the conclusion of the dormant period, move it back to a sunny interior window, and begin light watering. You can water a little bit more after you start to notice growth. Don’t add too much water, though, until you notice fresh growth.
Until growth begins to accelerate, keep it on the drier side but don’t forget to water.
This is also a wonderful time to divide the tubers and create as many new pots as you’d like if you’d like to grow more plants. You can divide your tubers whichever you like after the period of dormancy.
Keep things as they are if you only want a specimen plant, or you could pot it up to the next larger pot size.
Why do nighttime shamrock plant closings occur?
a time-lapse of O. triangularis leaves falling off at dusk. The 1.5-hour recording is made at 750 times the speed of real time.
When ambient light is high (during the day), the leaves of O. triangularis open, and when ambient light is low, they close (at night). The leaflets fold at the level of the central vein during this motion. Changes in the turgor pressure in the cells at the leaf base are what propel this movement, not growth. It demonstrates photonasty.
