Swedish ivy is an easygoing trailing houseplant, and when it struggles, the cause is usually how it is watered or where it sits rather than a disease. Despite its name, it is not a true ivy and does not come from Sweden; it is a relative of mint. Most fixes are changes to its routine, and the plant usually recovers as long as some healthy stems remain.
Wilting, Yellowing, or a Mushy Base From Too Much Water
Overwatering can cause root rot, so the soil needs to drain well.1Gardeners Supply. How to Care for Swedish Ivy Swedish ivy likes consistent moisture but not soggy soil.2Gardeners Supply. How to Care for Swedish Ivy Water thoroughly only when the top inch of soil feels dry to the touch.3Gardening Solutions. Swedish Ivy In winter, when growth slows, water less often.4Gardenia. Plectranthus verticillatus
The finger test works best when done properly. Push a finger in up to the first knuckle, which is about an inch. Hanging baskets dry faster at the top, so check the middle too. Lifting the pot now and then teaches you the difference between a wet weight and a dry one.
Rot can look like thirst, because both make the plant droop. One sign of rot is a plant that droops while its soil is still wet. Its stems feel soft and darken at the soil line. Rotten roots are brown, mushy, and may smell sour, while healthy roots are firm and pale. A thirsty plant perks up within hours of watering, and a rotting one doesn’t.
A well-draining potting mix, either general-purpose or peat-based, keeps air around the roots.5Gardenia. Plectranthus verticillatus A pot that is much too large holds extra wet soil the roots can’t use.6Epic Gardening. How to Plant, Grow, and Care for Swedish Ivy
If rot has already set in, slide the plant out of its pot and rinse the soil off the roots. Cut away every brown, mushy root with clean scissors. Repot into fresh, dry, well-draining mix in a pot with a drainage hole, then water lightly and wait for the top inch to dry before watering again. If the roots are mostly gone, root some healthy stem tips as backups, since cuttings root easily.
Scorched, Bleached, or Crispy Leaves From Too Much Sun
Too much light shows up as scorched or bleached leaves, curling or wilting, and dry, crispy edges.7Healthy Houseplants. Swedish Ivy Care Guide: Creeping Charlie Strong direct sun burns the leaves, so outdoors the plant should be kept in shade.8University of Florida IFAS. Swedish Ivy Scorch damage is irreversible on the leaves it affects.9Thursd. Swedish Ivy Care & Propagation Guide
Once the plant has been moved, trim badly scorched leaves, since new growth will replace them. Crispy edges can also come from very dry soil, so check the soil before blaming the light.
Scorch tends to show up on the leaves that face the window or sit at the top of the basket, while leaves shaded by other foliage stay green. Sun-bleached leaves look washed out and papery, unlike the soft, yellowing leaves of an overwatered plant, so feel the leaf as well as looking at it. Damage usually appears after a change, such as a new spot, a season when the sun sits lower and reaches deeper into the room, or a curtain being removed.
The plant does best in bright, indirect light, such as near an east- or west-facing window.10Gardeners Supply. How to Care for Swedish Ivy It can handle some direct sun in the early morning or late afternoon.11Thursd. Swedish Ivy Care & Propagation Guide Protect it from harsh afternoon light, for example with a sheer curtain, which works well over a sunny window.12Gardeners Supply. How to Care for Swedish Ivy13Gardenia. Plectranthus verticillatus
Summer outdoors needs care. Even plants used to a bright window burn quickly in outdoor sun, so hang baskets under a porch roof or a tree canopy. Move the plant outside gradually over a week so it can adjust. Outdoor pots dry faster, so check the soil more often.
Long, Leggy Stems and Pale Leaves
Too little light produces weak, leggy growth, meaning long, sparse stems with wide gaps between the leaves, along with pale leaves.14Thursd. Swedish Ivy Care & Propagation Guide The first fix is moving the plant to brighter indirect light. Trimming alone won’t fix this: if the light stays poor, the new shoots will stretch out thin again, so brighter light has to come first.
Regular trimming keeps the plant bushy and stimulates new growth.15Gardeners Supply. How to Care for Swedish Ivy Focus on stems that have stopped growing vigorously.16Thursd. Swedish Ivy Care & Propagation Guide
Cut just above a pair of leaves, where two new shoots will form. Trim a few stems at a time so the plant keeps enough leaves. For regular upkeep, pinching soft tips with your fingers is enough.
Trimmings can fill out the pot. Stem pieces four to six inches long root in water or moist soil within a few weeks. Strip the bottom leaves before rooting, then plant the rooted cuttings back into the same pot to fill bald spots.
A basket that goes bald on top has a similar cause. Long trailing stems drop their old leaves near the soil, and the crown gets less light than the trailing tips. Cutting some stems back hard near the soil restarts growth at the center.
Spots on the Leaves
A fungal leaf spot causes raised black spots, often sitting on white threads, on variegated Swedish ivy.17SFGate. Common Problems With Swedish Ivy and How to Handle Them A bacterial infection causes small dark gray spots near the leaf edges or in the middle of the leaf.18SFGate. Common Problems With Swedish Ivy and How to Handle Them As the bacterial spots grow, older leaves can drop.19SFGate. Common Problems With Swedish Ivy and How to Handle Them Both spread through splashing water from watering or rain.20SFGate. Common Problems With Swedish Ivy and How to Handle Them
Because the fungal problem is described mostly on variegated plants, a plain green plant with spots is a good reason to consider other causes too, such as sun damage. Scorch spots are dry and tan or bleached and tend to appear on the leaves facing the light, which is one clue they aren’t an infection.
Bacterial spots enlarge over time, so the oldest leaves, which have had the longest exposure, are the ones that yellow and drop. Check the whole plant, including the undersides and leaves hidden by dense growth, because the first spots are small and easy to miss.
To stop the spread, water at the soil rather than over the leaves. Remove spotted leaves and throw them in the trash, not the compost. Keep the plant apart from other plants until new leaves come in clean, and bring outdoor baskets under cover during rainy spells.
Misting raises humidity, but wet leaves help these spots spread. On a spotty plant, use a humidity tray instead.21Gardenia. Plectranthus verticillatus Good air movement also helps leaves dry quickly.
Spider Mites
Spider mites multiply fast in hot weather and can complete a generation in under a week.22UC Statewide IPM Program. Spider Mites / Home and Landscape / UC Statewide IPM Program They prefer hot, dusty conditions, and plants stressed by lack of water are especially susceptible.23UC Statewide IPM Program. Spider Mites / Home and Landscape / UC Statewide IPM Program
Mites are so tiny that you will usually notice the damage long before you see the mites themselves. Leaves get fine pale speckling and a dull color. Fine webbing may show between the stems, but early on there may be none, so lack of webbing does not rule mites out. Check the undersides of leaves first. A magnifying glass, or a phone camera zoomed in, can reveal them as tiny moving dots, and so can tapping a leaf over white paper.
Regular, forceful sprays of water often reduce mite numbers enough.24UC Statewide IPM Program. Spider Mites / Home and Landscape / UC Statewide IPM Program Cover the undersides of the leaves well.25UC Statewide IPM Program. Spider Mites / Home and Landscape / UC Statewide IPM Program If needed, use insecticidal soap or oil, testing it on part of the plant first.26UC Statewide IPM Program. Spider Mites / Home and Landscape / UC Statewide IPM Program
A simple routine is to rinse the plant in the shower or sink every few days for a couple of weeks. Tip the basket so the water reaches the undersides of the leaves. Keep watering regular so the plant isn’t stressed.
Sudden Leaf Drop From Cold or Drafts
Leaves often fall after the plant sits in a draft, near a cold window, or by a heater, or after a sudden temperature swing.27Botanicaly. Swedish ivy dropping leaves: causes and fixes The plant does best at average temperatures year-round.28Gardening Solutions. Swedish Ivy Move it away from doors, vents, and cold glass.
Cold isn’t the only suspect. Overwatering also causes leaf drop, so check the soil before blaming the temperature. Leaf spot drops older leaves, and a plant just moved to a new spot may shed some leaves as it adjusts.
Winter adds its own risks. Leaves touching cold glass can be damaged, and heating vents dry the air and soil quickly. Bring outdoor plants inside before nights turn cold.
Stable conditions bring new growth in a few weeks. Water less while the plant has fewer leaves, and trim bare stems to encourage new shoots.
Crowded Roots and When to Repot
Swedish ivy can become root bound, meaning its roots fill the whole pot.29Epic Gardening. How to Plant, Grow, and Care for Swedish Ivy Wait until the roots have filled the current pot, then repot in spring.30Epic Gardening. How to Plant, Grow, and Care for Swedish Ivy Go up only one to two inches in pot size, because extra soil stays wet and invites water problems.31Epic Gardening. How to Plant, Grow, and Care for Swedish Ivy Signs that it is time include roots growing out of the drainage hole, water running straight through the pot, and soil that dries out within a day or two.
When you repot, loosen circling roots gently with your fingers. Set the plant at the same depth as before. Water once, then let the top inch dry before watering again.
No Flowers
Missing flowers can come from too much nitrogen fertilizer, too little light, or both.32Gardening Solutions. Swedish Ivy The flowers are small spikes in white or pale lavender. Switch to a high-phosphorus, low-nitrogen fertilizer in spring and give the plant more natural light.33Gardening Solutions. Swedish Ivy
On a fertilizer label, the middle number is phosphorus. More light should not mean direct afternoon sun. Stopping fertilizer in fall and winter, when growth slows, also keeps the plant from being pushed into leafy growth at the wrong time.
Is Swedish Ivy Safe for Pets
The ASPCA lists Swedish ivy as non-toxic for dogs and cats.34Gardening Know How. Common Problems With Swedish Ivy and How to Handle Them Still, eating a lot of any plant can upset a pet’s stomach.
Residue from insecticidal soap is a better reason to keep pets off a recently treated plant. True ivies are toxic to pets, so check the plant’s label to be sure what you have.
