Oxalis Trio | Oxalis Triangularis - Oxalis Plum Crazy - Oxalis Sunset Velvet

The Oxalis Trio thrives in bright, indirect light, ideally placed 50 to 100 cm from an east or west facing window.

These three varieties originate from open, sunny areas of South America, where they receive consistent light without direct exposure to the afternoon sun. Indoors, a location near a bright window, but without intense direct sunlight, is ideal. In winter, move the pots closer to the light source to compensate for the reduced light.

Sufficient light is essential to preserve the intensity of the purple, plum, and copper hues of the leaves. Insufficient light results in pale foliage and leggy stems.

Important tip 🌿Avoid exposing these varieties to direct midday or summer sun, which can quickly burn their delicate, colorful leaves. Rotate the pots regularly to ensure even growth.For rooms with insufficient lighting, ourfull spectrum horticultural lampfaithfully imitates natural light, without the harmful UV rays.

The Oxalis Trio is moderately toxic to cats, dogs and young children.

Plants of the genus Oxalis contain soluble oxalates, including oxalic acid, which can cause irritation of the mucous membranes if ingested. These compounds, present in all parts of the plant, including the leaves and bulbs, are the same as those found in some common foods such as sorrel or rhubarb.

If ingested by an animal, the most common symptoms are excessive salivation, vomiting, loss of appetite, or temporary weakness. In rare cases, massive and repeated ingestion could affect the kidneys, particularly in cats. In children, symptoms are generally mild: mouth irritation and slight nausea.

What precautions should be taken on a daily basis?

Place your Oxalis plants up high or in a room inaccessible to animals and young children. The bulbs, often within reach during repotting, require particular attention.

By adopting a few simple placement precautions, the Oxalis Trio can absolutely coexist without major risk with your pets and children in your home.

The leaves of the Oxalis Trio most often turn yellow due to overwatering, lack of light, or nutrient deficiency.

• If the leaves turn yellow and become soft, the problem usually comes from excess water which causes the beginning of rot in the bulbs or roots.
• If the leaves gradually turn yellow while remaining firm and dry, the plant often lacks light or fertilizer, and the characteristic purple, plum, or coppery hues also fade.
• If the yellowing is accompanied by small light spots, a dull appearance or fine webbing, it may be a mite infestation, common indoors, especially in dry atmospheres.

It is important to note that the Oxalis trio naturally enters a period of dormancy, often in late summer or autumn: the stems and leaves then turn completely yellow and disappear. This process is perfectly normal and part of the biological cycle of these bulbous plants, which regrow vigorously the following spring.

Important tip 🌿One or two old leaves turning yellow from time to time is perfectly normal: it is part of the plant's natural cycle.On the other hand, there is cause for concern if several leaves turn yellow rapidly, if the phenomenon spreads to young leaves, or if growth slows down significantly.

In case of a mite infestation, prioritize ourplant-friendly biological treatments, effective and respectful of your home.

The Oxalis Trio is ideally repotted in spring, between March and May, when growth actively resumes after the winter dormancy period.

Repotting is necessary when:

• The bulbs are visible on the surface or emerge through the drainage holes.
• Growth is slowing despite favorable conditions.
• or that the substrate compacts too quickly after watering.

As a general rule, repotting every 2 years is sufficient for an adult plant.

Unlike many houseplants, the Oxalis Trio grows from small bulbs that need space to multiply: in a few seasons, the clump can become very dense and require division to maintain a vigorous shape.

Choose a pot 2 to 3 cm wider than the old one, and make sure it has drainage holes. Ourtransparent pots to monitor the rootsare ideal: their transparency allows you to observe the condition of the bulbs and roots after repotting without disturbing the plant.

We recommend ourwell-draining substrates enriched with biostimulantsdesigned to promote drainage and healthy growth. For Oxalis, use ourversatile substrate made in France, well-draining and balanced in nutrients.

1. Gently remove the plant from its pot by tapping the pot to loosen the root ball without pulling on the stems.
2. Gently separate the bulbs if the clump is too dense, taking care to keep the roots intact.
3. Place a layer of substrate at the bottom of the new pot, install the bulbs at a shallow depth, then fill in without burying excessively.

Important tip 🌿After repotting, water moderately to help the potting mix settle around the bulbs. Avoid overwatering in the following days to prevent rot. Repotting is always stressful: give your Oxalis a few weeks to settle in comfortably.

The Oxalis Trio should be fertilized every 2 to 3 weeks from March to October, with a liquid fertilizer diluted in the watering water.

During autumn and winter, from November to February, significantly reduce or stop fertilization. This is a period of vegetative rest during which the plant reduces its activity and may enter complete dormancy, with the leaves disappearing entirely until spring.

Since the Oxalis Trio consists of bulbous plants, a regular supply of nutrients during the growth period is essential to recharge the bulbs and ensure vigorous and well-colored regrowth after each dormancy.

A well-balanced intake promotes:

• denser foliage with intense colors,
• regular and even growth among the three varieties
• and improved plant resistance to seasonal variations.

👉 For best results, we recommend ourconcentrated fertilizer for houseplantsEasy to dose thanks to its graduated pipette, with results quickly visible on the color and vigor of the foliage.

Important tip 🌿Never fertilize your Oxalis Trio on a dry substrate: this could burn the bulbs and fragile roots.Water normally first, then apply the diluted fertilizer 2 to 3 days later, when the soil is slightly moist. Regular but moderate fertilization will keep your Oxalis Trio vigorous and displaying vibrant colors throughout the season 💚

Water the Oxalis Trio when the substrate has dried out completely, approximately every 7 to 10 days in summer and every 14 to 21 days in winter, depending on the plant's dormancy phase. Use room temperature water.

These bulbous plants are particularly sensitive to overwatering: their bulbs rot easily if the potting mix remains waterlogged. During dormancy, when the foliage has died back, almost completely stop watering and keep the potting mix only very slightly moist.

How do I know when to water?

The finger test remains the most reliable method: insert your index finger into the substrate to a depth of 2 to 3 cm. If the substrate is dry, it's time to water. If it's still damp, wait a few more days.

Important advice:When in doubt, it's always better to wait a little longer than to overwater. Oxalis bulbs tolerate a slight lack of water better than prolonged overwatering, which quickly causes them to rot and compromises their growth in the spring.

The Oxalis Trio is mainly propagated by division of the bulbs, ideally in spring, at the time of repotting, when the plant comes out of dormancy and begins to produce new leaves.

Bulb division: a method adapted to OxalisUnlike many houseplants that propagate from stem cuttings, the varieties in this trio reproduce naturally by producing numerous small bulblets around the main bulb. Simply separate these bulblets gently by hand or using a tool.Our stainless steel blade pruner ensures a clean and hygienic cut.ensuring that each bulbil is intact and has its roots.

1. Carefully remove the clump from the pot and identify the well-formed bulbils, distinct from the main bulb.
2. Separate them by hand or with your pruning shears, limiting injuries to reduce the risk of infection.
3. Plant each bulbil inOur transparent pots allow you to monitor root development.by placing them at a shallow depth in a slightly moist substrate.

For transplantation, use ouruniversal substrate enriched with essential nutrientsWell-draining and suitable for bulbous plants such as Oxalis. Keep the new pots in a bright and warm location, between 18 and 22°C, watering very sparingly until the first shoots appear.

Important tip 🌿Oxalis triangularis, Plum Crazy, and Sunset Velvet bulbils typically take 3 to 6 weeks to produce their first leaves. Don't worry if nothing seems to be happening in the first few days: growth is beginning underground. The most reliable sign of success is the appearance of the first characteristic little stems, heralding a new season of colorful foliage.
