Oxalis, also known as wood sorrel, is a genus of flowering plants in the family Oxalidaceae. There are over 800 species of oxalis, which are native to tropical and subtropical regions of the world. Many species of oxalis are grown as ornamental plants, and some are considered invasive.

How to Grow Oxalis - Planting & Caring

Growing Easiness

Is it easy to grow Oxalis plant? The Oxalis is a plant that is easy to take care of, which makes it a good choice for beginner gardeners or those new to floriculture. It is also a suitable plant for growing indoors.

Plant Size

How big can it be? While the leaves are typically around 5-15 cm long, the total size of the plant (including leaves and stem) is usually around 15-30 cm. This makes it a relatively small plant, which is why it is often used as decoration or as part of a larger arrangement. The leaves are usually a deep green, but can also be found in shades of purple or red. The flowers are small and white, with five petals each.

Growth Rate

How fast is the growth? The reason for its low growth is probably because it is a shade-loving plant and it is not getting enough sunlight. It is also possible that it is not getting enough water or nutrients. Another possibility is that it is being attacked by pests or diseases.

Oxalis Basic Knowledge

Plant Form Herbaceous
Family Oxalidaceae
Origin South Africa, South and Central America (Mexico)

Lifespan, Perennial or Annuals

How long is the lifespan? While most Oxalis species are not very long-lived, there are a few that are quite long-lived. For example, the South American species, Oxalis gigantea, can live for over 20 years, and the North American species, Oxalis crassipes, can live for over 10 years.

Ideal Temperature

What is the ideal temperature? When the temperature is too high, the leaves of the Oxalis plant will begin to fade in color. The ideal temperature for an Oxalis plant is 64.4 to 68 degrees Fahrenheit in the summer and no lower than 44.6 degrees Fahrenheit in the winter. Oxalis plants prefer cool conditions, but can also tolerate higher temperatures.


What about the humidity? The reason I choose this topic is because I think it is interesting how the plant reacts to different climates. For example, at lower temperatures the plant does not need as much humidity, but when the temperature rises, the plant benefits from being sprayed or kept in a pan with wet claydite.

Light Requirement

What amount of light this plant needed? The reason for this is that the Oxalis plant hails from South America where it grows in shady areas of the rainforest. However, it will do just fine with some direct sunlight, especially in the morning hours. If you live in an area with very hot summers, then some afternoon shade will be appreciated by your Oxalis plant.

Soil Composition

What is good soil for Oxalis? When planting Oxalis, it is important to remember that the plant does best in light, fertile soil that is slightly acidic. A mix of foliar humus, sand or perlite, and garden soil is perfect for Oxalis. You can also use a mix of sod, leaf, and sand. Whichever mix you choose, make sure that the soil drains well. Oxalis is not suitable for calcareous soil.

Watering Time

How much I must water Oxalis? The plant should have a moist, but not water-logged soil. In summer, the soil should dry slightly between watering (pour every 4-5 days), in winter watering is limited; pour with warm soft water.

Fertilizing and Nutritient

About fertilizer. So, if you see the leaves of your Oxalis plant turning yellow and/or the plant not flowering as much as it used to, it is time to fertilize it. The best way to do this is to use a soluble fertilizer that is high in phosphorus.


How to reproduce Oxalis? Since it is a plant, it must reproduce in some way in order to create more of the species. This specific plant can reproduce in three ways: through seeds in the spring, by dividing the plant during transplantation, and by leaf cuttings. It is best to plant the seeds in a mixture of wet peat and perlite, and then cover the pot with the plants using a plastic bag secured with an elastic band. The plant should be placed in indirect sunlight. If the seeds are not old, they should germinate well. After germination, the seedlings can be transplanted into a permanent earthen mixture in a separate pot. The plant can also be propagated by nodules (acidic hezaria), which are planted in October or February-March to a depth of 1 cm. Oxalis reproduces by leaf cuttings by taking individual leaves with petioles and germinating them in water or sand. In the spring, the roots will form quickly. Several leaves can be planted in one pot.


Why Oxalis won't bloom? If you have ever seen a white, pink, or purple flower collected in an umbrella, then you have seen an Oxalis plant in bloom. Oxalis is a genus of flowering plants in the wood-sorrel family. They are native to Europe, Asia, and South America, but some species have become naturalized in other parts of the world.

Transfer or Repotting

How much I must water Oxalis? The plant is well transferred, as the pot is filled with rapidly growing nodules. Young plants are transplanted annually in the spring, adults – every 2-3 years.

Caring The Oxalis

How to care the plant? Because leaves are formed at night, the plant is better to take out in the garden or on the balcony during summer months. For about two months in winter, the Oxalis Depp plant discards its leaves. Its bulbs should be stored in a cool room, and the soil should be occasionally watered.

Pests & Challenges

What is the challenge when caring Oxalis plant? Although it is a beautiful plant, it is often sick. The main diseases that affect it are mealybugs, whitefly, aphids, and spider mites. If you water it too much, the plant may rot. And if you don't water it enough, the leaves will wither. To prevent these problems, you need to water the plant regularly and in bright light.

Toxic & Poisonous Type

Are Oxalis poisonous? The plant contains small crystals of oxalate, with prolonged use can cause kidney problems, as well as nausea, vomiting and diarrhea.
