Strawberry Begonia is not a true begonia at all — it is Saxifraga stolonifera, a trailing plant with soft, rounded leaves in green and silver, with red undersides and red stems. It sends out long, thin runners tipped with baby plantlets, like a strawberry plant, which is how it got its name.
It trails and spreads, making it a good hanging plant or a plant for the edge of a shelf where the runners can dangle. The plantlets on the runners are ready-made new plants, so this is one of the easiest begonias to multiply — and one of the prettiest when it is allowed to trail. The runners are the charm and the challenge: a plant that is happy will send out runners everywhere, and a plant that is dry or cold will drop leaves and stop trailing. Keep it moist, humid and warm, and let it trail. This guide covers exactly what it needs: light, watering, humidity, temperature, soil, repotting, feeding, propagation and the common problems that show up when something is off.

Light
Give your Strawberry Begonia bright indirect. Bright indirect light keeps the silver markings vivid and the growth full. In too little light the leaves go plain green and the plant stretches, with long bare runners and few leaves. Avoid direct sun, which scorches the soft leaves, and give it a spot where the trailing runners get light too, not just the top of the pot. Our grow-light calculator can help work out whether your spot is bright enough, and our sunlight calculator can help you check how much light a window really gets through the day.
Watering
Water as follows: weekly; keep soil lightly moist, avoid wet leaves. Water weekly and keep the soil lightly moist, watering at the base and keeping the leaves dry. Water thoroughly until it runs from the drainage holes, then empty the saucer. Let the top of the soil dry slightly between waterings, and ease off a little in winter — but do not let the whole pot dry out, or the plant will drop leaves. Our watering calculator gives a starting point for your pot size, and the watering schedule generator can help you build a routine around it.
Humidity and temperature
Strawberry Begonia needs moderate to high humidity and temperatures of 65–75°F (18–24°C). Strawberry Begonia likes moderate to high humidity, and dry air shows as brown, crispy leaf edges. Grouping plants together or a pebble tray helps, and a humidifier is the reliable fix in a dry home. Do not mist the soft leaves — wet foliage invites mildew — and keep the plant out of dry draughts. Our humidity and temperature checker can tell you whether your room suits this plant. Temperature matters just as much as humidity: keep it away from cold windows in winter, from radiators that dry the air, and from air-conditioning vents that blast cold air directly at it.
Soil and potting
Indoors, this plant needs a rich but very free-draining potting mix. A light, free-draining mix suits it: potting soil with perlite and a little coco coir. The pot must have drainage holes, and a hanging pot or a pot on a high shelf suits the trailing habit. Let the runners hang, or pin a plantlet into a neighbouring pot of mix while it is still attached to the parent — see Propagation below. Our potting-mix calculator can work out the parts for a homemade mix for your pot size, and our soil volume calculator can work out how much mix you will need.
Repotting
Repot every 1–2 years, in spring, or sooner if roots are circling the drainage holes. Repot in spring when roots are circling the drainage holes, moving up only one pot size. Strawberry begonias grow fast when happy, so check the roots each spring. Repotting is also a good moment to trim back long runners and to pot up plantlets — see Propagation below. Our repotting calculator can help you work out the next pot size and how much fresh mix you will need.
Feeding
Feed during the growing season, in spring and summer, with a balanced liquid houseplant fertiliser at half the strength on the label, roughly once a month while the plant is actively growing. Feed in spring and summer with a balanced liquid fertiliser at half strength, about once a month while it is actively growing. It is a light feeder, and excess fertiliser burns the leaf edges. Do not feed in autumn and winter when growth slows. Our fertiliser calculator can help you work out the right amount for your pot size. Always follow the directions on the label — more fertiliser is not better, and excess salts build up in the soil and burn the roots.
Propagation
Strawberry Begonia is one of the easiest plants to propagate: the runners do the work for you. Each runner ends in a baby plantlet with tiny roots. Pin a plantlet into a small pot of moist, free-draining mix while it is still attached to the parent plant, keep it lightly moist, and once it has rooted — usually within a few weeks — cut the runner and you have a new plant. You can also snip plantlets off and root them in water or mix. Keep new plantlets warm and bright, out of direct sun, while they establish.
Common problems and fixes
| Problem | Likely cause | Fix |
|---|---|---|
| Dropping leaves | overwatering or cold | Check soil moisture and cold draughts; keep watering steady and the plant settled. |
| Leggy growth | too little light | Move to brighter light; prune back long stems to encourage branching. |
| Powdery mildew | wet leaves and poor air flow | Keep leaves dry; improve airflow and remove affected leaves. |
Dropping leaves
Likely cause: overwatering or cold. Dropping leaves usually mean the plant is stressed by overwatering or by cold. Check the soil first: if it is soggy, let it dry out and check that the pot drains freely. If the soil is fine, look for cold — a draught, a cold window, or a sudden move to a much cooler spot can all make this plant shed leaves. Move it somewhere warm and settled, keep watering steady, and it should stop dropping leaves once it settles; new growth follows in the growing season.
Leggy growth
Likely cause: too little light. Leggy growth — long, bare stems with leaves spaced far apart — means the plant is reaching for more light. Move it to a brighter spot with the light level given in the table above, and prune back the longest stems to encourage branching from lower down. Do not expect the stretched stems to fill back in on their own; the fix is brighter light plus a trim, and the cuttings can usually be propagated. Our grow-light calculator can help check whether your spot is bright enough.
Powdery mildew
Likely cause: wet leaves and poor air flow. Powdery mildew shows up as a white, powdery coating on the leaves, and it thrives where leaves stay wet and the air does not move. Water at the base of the plant, never over the leaves, and give the plant space and gentle air circulation so the foliage dries. Remove badly affected leaves, improve airflow, and keep the leaves dry — mildew spreads fast in still, damp air, so early action matters. Our plant disease checker can help confirm what you are looking at.
Frequently asked questions
How often should I water Strawberry Begonia?
weekly; keep soil lightly moist, avoid wet leaves. Water weekly and keep the soil lightly moist, watering at the base and keeping the leaves dry. Check the soil with your finger before you water — the surface can look dry while the soil below is still wet, and the plant's needs change with the season, the pot size and the light.
How much light does Strawberry Begonia need?
It needs bright indirect. Bright indirect light keeps the silver markings vivid and the growth full. Too little light gives stretched, pale growth, and harsh direct sun — where it is not wanted — scorches the leaves.
Is Strawberry Begonia safe for cats and dogs?
According to the data used for this guide, this plant is toxic to cats and dogs. Keep it out of reach of pets that chew plants, and if a pet eats any of it, contact your vet.
How do I propagate Strawberry Begonia?
Use the runners. Each runner ends in a baby plantlet — pin it into a small pot of moist mix while it is still attached to the parent, keep it lightly moist, and cut the runner once it has rooted, usually within a few weeks. It is one of the easiest houseplants to multiply.
What should I do if my Strawberry Begonia looks unhappy?
Start with the basics: check the soil moisture, the light, and the temperature, and look at the problems table above. Most unhappy houseplants are unhappy about water, light or cold, not about a rare disease — fix the care first, give the plant a few weeks, and judge it by the new growth, not by the damaged leaves, which will not heal.
