Types of Oxalis Plants

Overview of the different types of Oxalis plants

Oxalis, commonly known as wood sorrel, is a large family of plants within the Oxalidacea family. There are over 800 species of Oxalis worldwide, many of which are grown as ornamental plants or as edible vegetables.

The most common types of Oxalis plants include the Popular Shamrock (Oxalis triangularis), the Purple Shamrock (Oxalis regnellii), and the Iron Cross Plant (Oxalis adenophylla).

All three of these varieties have similar growth habits and characteristics such as clover-like foliage with small, cup-shaped flowers that come in shades of white, yellow, and pink.

Discussion on the different growth habits and characteristics of each type

The Popular Shamrock has a clumping habit and produces bright green, trifoliate leaves with purple undersides. The blooms are white or pink in color and appear during springtime. This variety can be found growing in grasslands or along woodland edges throughout Europe.

The Purple Shamrock is identified by its red-tinged leaves and mauve flowers that bloom from early summer to early fall.

While it’s not as hardy or vigorous as the Popular Shamrock, this variety can still tolerate colder temperatures than those found in tropical regions.

It is often used as a houseplant decor because of its showy foliage and delicate blooms.

Lastly, we have the Iron Cross Plant which is an evergreen perennial with deep-green foliage that features four leaflets arranged in an X shape.

This type of Oxalis produces fragrant white flowers during mid-springtime followed by dark-purple berries throughout autumn to winter months.

It typically grows between 10–15 cm high when mature and prefers well-drained soil in partial shade to full sun exposure for optimum growth.

Oxalis Plant Care


Oxalis plants, also known as shamrocks, require bright light to thrive and bloom.

They do best in full sun or partial shade, with at least six hours of direct sunlight per day.

Too little light can cause the leaves to become pale and limp, while too much light will cause them to wilt and burn.

The amount of sunlight needed depends on the variety of Oxalis being grown; some varieties are more tolerant of shade than others.

The effects that light has on Oxalis growth and development are many. Light is essential for photosynthesis, which is the process by which plants create their own food from water, carbon dioxide, and energy from the sun.

During photosynthesis, plants use the energy from sunlight to turn water and carbon dioxide into carbohydrates such as glucose.

These carbohydrates provide the plant with fuel for its growth processes such as cell division and cell expansion.

Sunlight also helps stimulate flowering in Oxalis plants by triggering a process called photoperiodism that causes the plants to flower when days become shorter in winter or during springtime when days begin to grow longer again. Without adequate sunlight, flowers may not form properly or at all.

Too little light can leave Oxalis plants susceptible to disease or fungus due to weakened immune systems caused by a lack of nutrition or energy reserves.

Oxalis plants require moderate amounts of water. It’s important to allow the top inch or two of soil to dry out between watering cycles.

It is also a good idea to check the moisture level with your finger or a moisture meter before watering. If the soil still feels moist at the surface, it likely does not need additional water.

When you do water your Oxalis plant, make sure that the entire root system gets saturated with water. It is best to use lukewarm water and be sure to avoid getting any water on the foliage as this can cause issues such as rot and fungal diseases.

Over-watering an Oxalis plant can lead to root rot and other fungal diseases caused by moisture sitting in the soil for too long.

This can stunt growth and even cause death if left unchecked. On the other hand, under-watering an Oxalis plant can cause wilting of leaves, yellowing, leaf drop, and stunted growth due to lack of nutrients from insufficient hydration.

Tips On How To Properly Water Oxalis Plants

When it comes time to water your Oxalis plants, start by checking the moisture level using your finger or a moisture meter before deciding whether additional water is needed.

If so, apply lukewarm water until you see some drainage coming through at the bottom of the planter or pot this will ensure that all of the roots are fully saturated with moisture.

Avoid splashing any excess water onto the foliage which can lead to rot and other fungal diseases. Allow for proper drainage after each cycle of watering so there is no standing water left in the soil for extended periods of time.

Consider adding a layer of organic mulch around your plants which will help preserve moisture levels in between watering cycles as well as protect them from temperature fluctuations during colder months.


The ideal soil for Oxalis plants is loose, well-draining, and slightly acidic; with a pH level ranging from 6.0 to 7.0.

These conditions help ensure that the plant’s roots don’t become waterlogged or overly dry, promoting the healthy growth of these low-maintenance houseplants over time.

Suitable soils for growing Oxalis include a lightweight mix created specifically for indoor planting or a mixture of potting mix, perlite, and vermiculite with equal parts of each ingredient. For outdoor planting in warmer climates, a combination of organic compost and sandy loam will work perfectly.

When planting an Oxalis in its permanent spot, dig a hole twice as wide as the root ball but only as deep as its existing container.

Loosen up the native soil at the bottom of your hole to provide adequate drainage and incorporate some peat moss or compost into the backfill soil to make sure your chosen location offers all the necessary nutrients during growth season.

After planting your newly acquired Oxalis, give it some time to acclimate before providing it with regular watering and fertilizer applications throughout its life cycle.

Soil for Oxalis Plant


Oxalis plants are relatively easy to care for and do not require a great deal of fertilizer. However, providing them with some fertilizer every month or two will help them grow and stay healthy.

The fertilizer requirements for Oxalis plants vary depending on the type of soil they’re in, but typically a balanced 10-10-10 or 20-20-20 NPK (nitrogen-phosphorus-potassium) ratio is recommended.

If the soil you have for your Oxalis plant it is more acidic, a fertilizer with higher sulfur content can be used. It’s also important to ensure that the fertilizer is well-balanced an unbalanced NPK ratio could lead to nutrient deficiencies and other growth issues.

Organic fertilizers such as compost, fish emulsion, manure tea, seaweed extract, and bone meal are all great options for Oxalis plants because they release their nutrients slowly over time which reduces the risk of burning your plant.

Using organic fertilizers helps increase the microbial activity in the soil which helps create a healthier environment for your plant.

Tips on how to properly fertilize Oxalis plants

In order to properly fertilize your Oxalis plant, start by understanding what kind of soil it’s planted in and then adjust your fertilizer accordingly.

When applying fertilizer, try to avoid getting any on the leaves as this can burn them. Watering before applying fertilizer will help it reach the roots faster which will help prevent any burning from contact with foliage.

Finally, after applying the fertilizer make sure you water it thoroughly so it gets distributed evenly through the soil.

Temperature and Humidity

The ideal temperature for Oxalis plants is between 60°F and 75°F, with a humidity level of around 40-60%. They can tolerate temperatures as low as 45°F, but it can cause damage to the leaves.

Temperatures above 80°F can cause scorching of the foliage and could eventually lead to death. High humidity levels can also cause disease issues in Oxalis plants, so it is important to keep the humidity levels down.

Extreme temperatures and humidity levels can have adverse effects on Oxalis plants. Low temperatures can prevent growth or even kill the plant, while high temperatures can cause wilting, leaf scorch, and eventual death.

High humidity levels can encourage fungal diseases such as powdery mildew or botrytis blight to develop on the plants.

Tips on how to properly manage the temperature and humidity levels for Oxalis plants

To properly manage the temperature and humidity levels for Oxalis plants, make sure they are placed in an area where they will receive bright light but not be subjected to direct sunlight or extreme temperatures.

Consider using fans to circulate air around them if the airflow is limited in their location. Plant them in pots with drainage holes that are filled with well-draining potting soil; this will allow excess moisture to drain away from the roots and help regulate soil moisture levels.

If you live in a humid climate then invest in a dehumidifier for your home; this will help keep your indoor environment at a lower humidity level that’s more suitable for your Oxalis plants.

Lastly, water as needed based on soil moisture levels (not according to a regular schedule) too little water will dry out the soil while too much water will cause root rot so it’s important to check the soil moisture level regularly before deciding when or how much water your plant needs.

Pruning and Propagation

Proper pruning of Oxalis plants is essential to ensure they continue to thrive, maintain their shape, and promote healthy growth.

When pruning, it’s important to use sharp scissors or gardening shears and remove any dead or discolored leaves or stems as needed this will help keep the plant looking attractive while allowing for adequate airflow and light penetration.

It can be beneficial to cut back the stem after each bloom period in order to encourage new growth this should be done by cutting just above a leaf node, which is where a leaf meets the stem.

Propagating Oxalis plants can be done in several ways, including the division of existing clumps, taking cuttings from existing stems/leaves, or sowing seeds collected from mature plants.

Division of existing clumps is perhaps the simplest method of propagation; simply dig up an established clump and split it into sections before replanting them in separate pots or containers.

Taking cuttings from existing stems/leaves involves cutting off 2-3 inches of the stem (again using sharp scissors) before placing it into soil or water until it develops roots; once roots have established themselves you can then replant them into individual containers with fresh potting soil.

Finally, sowing seeds collected from mature plants involves collecting seed heads when they turn brown before gently pressing them into moist soil in individual containers; once these have germinated you can then transplant them into larger pots/containers as needed.

Proper pruning of Oxalis plants

Tips on how to properly propagate Oxalis plants

In order to properly propagate Oxalis plants there are several steps that must be taken to ensure a successful outcome:

Firstly, make sure your tools are clean and sterilized before use this will reduce the risk of disease transmission when handling multiple plants.

Secondly, always take cuttings from healthy stems/leaves and try to avoid any that show signs of wilting or discoloration as these are more likely to fail when propagating.

Thirdly, make sure that whatever substrate you choose such as soil or water is always kept moist but not overly saturated this will provide ideal conditions for root development during propagation.

Finally, remember that different varieties of Oxalis may require slightly different techniques when propagating so make sure you do your research beforehand!

Common Problems and Solutions

Too much sun exposure

This can cause the leaves to become brown and shrivel, reducing their growth rate.


When too much water is given to the plant, it causes root rot which can lead to plant death. It’s important to make sure that the soil around the roots drains well and that only small amounts of water are given regularly.


Pests such as aphids, whiteflies, and mealybugs these pests feed on the sap of the leaves which leads to yellowing and wilting. To get rid of them, spraying with a soap or neem oil solution should do the trick.

Poor soil quality

Having poor soil quality means that there are not enough nutrients for the plant to absorb leading to weak stems and pale-colored leaves. This issue can be solved by adding compost or manure into the soil for better nutrient absorption by the plant.

Tips on how to identify and solve these problems for Oxalis plants

Make sure to check your Oxalis plants often so that any issues can be spotted early on before they become too severe which could lead to permanent damage or death of your plant.

Pay attention to any changes in the color or texture of its leaves as this could indicate an underlying problem with nutrition or environmental conditions like sunlight, humidity, etc.

When providing sunlight ensure that it’s filtered light instead of direct sunlight as this will help prevent leaf burn due to overexposure which could reduce your plant’s growth rate significantly.

Taking proper care when watering is essential in order for your plant’s root system to stay healthy without getting rotted due to overwatering; make sure that you plan out when you water its soil (e.,g., once a week).

Provide only small amounts each time in order for it keeps an adequate level of moisture but not too much where it would drown its roots system instead; additionally ensure that you check if its soil has good drainage before watering it again in order to avoid root rot altogether from developing due bad drainage conditions within its pot substrate material(e.,g., peat moss).

If you notice any signs of pests make sure that you take immediate action in order to prevent them from spreading throughout your plant.

Spraying a solution made out of either soap or neem oil has proven effective results against many insect infestations as both contain active ingredients strong enough to deter pests from feeding off from your Oxalis foliage without harming it at all.

If done regularly these solutions should help keep them away permanently until new infestations arise again later on down the line which could then be treated with the same solutions again if necessary.


The Oxalis plant is an interesting and easy-to-care-for species that can make a glorious addition to any home, garden, or balcony. Not only is it attractive and eye-catching, but its low maintenance requirements mean it requires relatively little attention.

All it needs is the right potting soil with good drainage capabilities, the perfect amount of light and water, regular pruning to keep its shape and size in check, and a few special touches like liquid fertilizer every now and then to keep it healthy and flourishing. If you are looking for an easy-going powerhouse of a houseplant, look no further than the Oxalis Plant.
