Baby Tears

Soleirolia soleirolii · Urticaceae

Easy Pet-safe Low-light tolerant

Soleirolia soleirolii is a low-growing, mat-forming perennial native to islands of the western Mediterranean, particularly Corsica, Sardinia, and nearby areas. It produces a dense, moss-like carpet of tiny, rounded leaves on delicate, interlocking stems and is widely grown as a ground cover or trailing houseplant. Its vigorous, spreading habit makes it well suited to terrariums, hanging baskets, and the edges of containers.

How to care for Baby Tears

Light

Baby Tears thrives in bright, indirect light and will perform adequately in lower-light situations, making it one of the more shade-tolerant houseplants. Direct summer sun should be avoided as it quickly scorches the delicate foliage, causing browning and die-back. A north- or east-facing windowsill, or a position set back from a bright window, is ideal indoors.

Watering

This plant requires consistently moist compost and is notably less forgiving of drought than many houseplants; even brief drying out can cause the foliage to wilt dramatically, though it often recovers if watered promptly. Water thoroughly and allow excess to drain freely, never leaving the pot sitting in standing water for prolonged periods, as waterlogging leads to root rot. Reduce watering slightly in winter when growth slows, but do not allow the compost to dry out completely.

Soil and potting

A moisture-retentive yet well-draining compost is essential. A peat-free multipurpose compost mixed with perlite or grit in roughly a 3:1 ratio works well, providing adequate aeration while retaining enough moisture to suit the plant's needs. Avoid heavy, compacting mixes that restrict drainage.

Feeding

Apply a balanced, diluted liquid fertiliser at half the recommended strength once a month during the active growing season from spring through to early autumn. Feeding is not necessary during winter. Over-feeding can cause excessive, leggy growth and should be avoided.

Humidity and temperature

Soleirolia soleirolii prefers higher humidity levels of 50% or above and can struggle in the dry air typical of centrally heated homes. Misting the foliage, placing the pot on a pebble tray filled with water, or grouping plants together will help raise local humidity. It tolerates a relatively cool temperature range of 10 to 24 C and actually prefers cooler conditions; it dislikes temperatures above 26 C and should be kept away from radiators and draughts.

Repotting

Repot in spring when the plant has visibly outgrown its container or when roots begin emerging from the drainage holes. Choose a pot only one size larger, as very large pots can hold excess moisture and increase the risk of root rot. Shallow, wide containers or pans suit its spreading habit particularly well.

Pruning

Baby Tears requires minimal formal pruning. Trim back any straggly or overgrown stems with scissors to maintain a tidy, compact shape, and remove any yellowing or dead portions promptly to encourage fresh growth. Because of its vigorous spreading habit, occasional trimming keeps it from overwhelming other plants in mixed plantings or terrariums.

Is Baby Tears toxic?

Pets: Non-toxic. Soleirolia soleirolii is not listed as toxic to cats or dogs by the ASPCA and is generally considered non-toxic to pets.
People: Not considered toxic to humans; however, ingestion by young children is not advisable as a general precaution.

Common problems

Wilting, collapsed foliage
Likely cause: Underwatering or the compost drying out  Fix: Water thoroughly and immediately; the plant usually recovers within an hour or two. Review watering frequency to prevent recurrence.
Yellowing leaves and mushy stems
Likely cause: Overwatering or waterlogging leading to root rot  Fix: Allow the compost to partially dry, improve drainage, and remove any rotten roots. Repot into fresh compost if the problem is severe.
Brown, scorched or crispy patches on leaves
Likely cause: Exposure to direct sunlight or very dry air  Fix: Move the plant out of direct sun to a position with bright, indirect light, and increase ambient humidity.
Pale, elongated or straggly growth
Likely cause: Insufficient light  Fix: Move the plant to a brighter position with more indirect light, or supplement with a grow light.
Tiny insects visible on foliage; sticky residue or distorted growth
Likely cause: Infestation by fungus gnats, aphids, or spider mites  Fix: Treat with an appropriate insecticide or neem oil solution; for fungus gnats, allow the surface of the compost to dry slightly between waterings and use sticky traps.
Grey, fuzzy mould on foliage or compost surface
Likely cause: Botrytis (grey mould) caused by poor air circulation combined with high humidity and cool temperatures  Fix: Remove affected material, improve air circulation around the plant, and avoid wetting the foliage when watering.

How to propagate

Division

Gently divide the plant into sections at any point during the growing season, ensuring each section has roots attached. Pot each division into moist compost and keep in a humid environment until established.

Stem cuttings

Take small clumps of stems with a few roots attached and press them firmly onto the surface of moist compost in a new container. Keep covered or in a humid spot; they root readily and quickly without the need for rooting hormone.

Where Baby Tears comes from

Native to Corsica, Sardinia, Balearic Islands, Italian peninsula (limited coastal areas).

Story and origins

The genus name Soleirolia honours Joseph François Soleirol (1796 to 1863), a French army officer and keen botanist who collected extensively in Corsica and Sardinia during the nineteenth century and is credited with introducing the plant to wider horticultural attention. The species epithet soleirolii is a Latinised form of his surname, a common practice in botanical nomenclature to honour the collector or describer of a species. An older synonym, Helxine soleirolii, derives from the Greek 'helxine', a name used by ancient Greek writers for various small, creeping plants.

Soleirolia soleirolii was collected and described in the early nineteenth century, largely through the efforts of Joseph Soleirol on the Mediterranean islands of Corsica and Sardinia, where it grows naturally in shaded, humid rocky habitats and stream banks. It was introduced to British gardens during the Victorian era and rapidly gained popularity as a ground cover for ferneries, terrariums, and shaded borders. Its ease of propagation and vigorous spreading habit meant it spread widely through cultivation across western Europe, the British Isles, and beyond, eventually naturalising in mild, damp regions where it was not native. Today it remains a popular choice for indoor terrariums and bottle gardens, and its diminutive form has made it a persistent fixture of the houseplant trade throughout the twentieth and twenty-first centuries.

Features green leaves edged or flecked with cream or silver, offering ornamental interest while retaining the same compact habit.

Soleirolia soleirolii 'Silver Queen'

Produces pale silvery-green foliage that appears almost white in bright conditions, valued for its soft, luminous appearance.

Fun facts

Baby Tears FAQ

Why has my Baby Tears plant suddenly wilted and collapsed?
This is almost always caused by the compost drying out. Baby Tears is particularly sensitive to drought and wilts rapidly when underwatered. Water the plant thoroughly straight away; it usually recovers within an hour or two. If the compost was wet rather than dry, root rot from overwatering may be the cause, and you should check the roots and repot if necessary.
Can I grow Baby Tears in a terrarium?
Yes, Baby Tears is an excellent terrarium plant. It thrives in the consistently high humidity and moist conditions of an enclosed or semi-enclosed terrarium and creates an attractive, moss-like carpet effect. Bear in mind that it spreads vigorously and may need trimming to prevent it from overwhelming other plants.
Is Baby Tears safe for cats and dogs?
Yes. Soleirolia soleirolii is not listed as toxic to cats or dogs by the ASPCA and is generally regarded as a pet-safe houseplant.
How do I stop my Baby Tears from going brown?
Browning is most commonly caused by direct sunlight, dry air, or the compost drying out. Move the plant away from direct sun, increase humidity by misting or using a pebble tray, and ensure the compost remains consistently moist. Browning in winter near a radiator is a common problem and can be resolved by moving the plant to a cooler, more humid spot.
How quickly does Baby Tears grow and spread?
Baby Tears is a vigorous grower during the warmer months of spring and summer. Under good conditions it can spread to cover a container or the floor of a terrarium quite rapidly, sometimes within a single growing season. Growth slows considerably in winter.
Can Baby Tears be grown outdoors in the UK?
Yes, in mild, sheltered parts of the UK it can be grown outdoors as a ground cover in shaded, moist positions. It tolerates light frost but is damaged by hard frosts. Be aware that it can become invasive in gardens, spreading into cracks in paving and lawns and proving difficult to remove completely once established.
How do I propagate Baby Tears?
The easiest method is division. Simply break off a clump of stems, ensuring a few roots are attached, and press it onto the surface of moist compost in a new pot. Keep it in a humid spot and it will establish and spread quickly without any additional treatment.
