String Of Bananas: Growing Curio Radicans Indoors
Are you looking for a hanging succulent plant that is easy to maintain and cool as can be? Here are care and growing tips for the String Of Bananas houseplant.
Everyone seems to be madly in love with that wacky and wonderful succulent String Of Pearls, and rightfully so. Did you know there’s another adorable “string” succulent on the block?
This one is easier to keep alive and just as attractive as its close relative, in my humble opinion anyway. Let me introduce you to or reacquaint you with the String Of Bananas houseplant and how to grow it.
Botanical Name: Curio radicans, formerly Senecio radicans Common Name: String Of Bananas

String of Bananas Traits
I think growing a String Of Bananas as a houseplant is easier than its Curio relative String Of Pearls. The stems are thicker, which makes them less delicate. They grow faster, which enables more propagation. The bananas don’t dry out like the String Of Pearls with those thin stems.
I’ve had readers say that SOBs are much easier to keep alive and have had zero luck with String Of Pearls. Why don’t you give this one a try?
Size
String Of Bananas plants are sold in 3″, 4″, and 6″ inch pots. The trails on mine are currently 4′ long. Those trails can reach 6′ long. This plant is a ground cover when growing in its native environment.
Growth Rate
Mine grows moderately to fast outdoors. You can expect a moderate growth rate indoors, given the plant has enough light.
Uses
A hanging basket or hanging pot suits this succulent to a tee. It can also be placed in a decorative pot and put atop a bookcase, shelf, ledge, etc., to hang down and show off those beautiful trails.

String Of Bananas Light Requirements
This trailing succulent needs as much light as possible indoors, in a medium to high exposure. If it’s in lower light, it won’t grow much, if at all.
You can grow it in or near a sunny window indoors. Just be sure to keep it out of the hot, direct sun (especially in the summer months), and make sure it’s not touching any hot glass. Either way, the plump leaves will burn.
If it’s not getting bright light from all sides, you’ll have to rotate it every 3-6 months so it does.
You may need to move it in the winter months to another spot in your home so it will get an adequate amount of light.

String Of Bananas Watering
It’s hard to give you a particular watering schedule because many factors play. Here are a few: the pot size, the type of soil it’s planted in, the location where it’s growing, and your home’s environment.
Watering every 2-3 weeks is a good ballpark. Water your String Of Bananas thoroughly, and let the soil dry out before watering again.
They, like all succulent plants, are subject to root rot. Don’t keep the soil constantly moist but don’t keep it dry for too long.
A common problem with succulents is keeping the soil too wet. You may find this guide helpful in knowing How Often Should You Water Succulents.
Temperature
As I always say: if your home is comfortable, your plants will be happy too. Normal house temperatures are just fine.
Even though this plant can tolerate a wide swing of temperatures outdoors, make sure it’s not sitting next to or on a heater or air conditioner. They don’t like hot or cold drafts.
Fertilizing/Feeding
The time for fertilizing and feeding is spring and summer into early fall if you’re in a temperate climate.
String Of Bananas aren’t fussy or needy regarding fertilizing. I fertilize mine with Grow Big, Liquid Kelp, and Maxsea or Sea Grow three to four times during our long growing season. I alternate these liquid fertilizers and don’t use them all together.
You may have a shorter growing season and only need to feed yours twice yearly in spring and summer, at half the recommended amount.
I sprinkle a thin layer of local worm compost/compost on all my houseplants every other year. Both enrich the soil naturally, so the roots are healthy and the plants grow stronger. If you go this route, easy does it. Too much of an application of either can burn a houseplant’s roots.
String Of Bananas Soil
A high-quality succulent and cactus soil mix is best for this plant. You want the potting mix to be light and well-drained so the roots don’t rot.
I use this DIY Cactus and Succulent Mix Recipe that’s very chunky, so the water drains right through. It’s the same blend I use for my indoor and outdoor succulents.
If you can’t find a mix locally, the ones I’ve used available online include Dr. Earth, EB Stone, Bonsai Jack, and Tanks’. Other popular choices are Superfly Bonsai, Cactus Cult, and Hoffman’s.
Regular potting soil isn’t ideal, but you can use it in a pinch. You’ll want to up the ante on the drainage factor to lessen the chance of rot by adding some pumice or perlite.
Repotting String Of Bananas
The best time for succulent repotting is during the active growing season: spring, summer, into early fall. This plant is easy to repot because the leaves don’t fall off as readily as other hanging succulents like the String Of Pearls and the Burro’s Tail Sedum.
Succulents can stay tight in their pots for a while, so don’t think you must repot this plant every year or two. I repot mine every 3-5 years if only to give it a freshen-up on the mix.
When it’s time for SOBs repotting, I generally go up one pot size. For example, from a 4″ pot to a 6″ pot.
Make sure the crown of the plant (the top part where all the stems grow out of) is no further down in the pot than 1″. If a String Of Bananas is planted too far down in the pot, it’ll be subject to stem rot.
Planting in a pot with multiple drainage holes is the best way to ensure the excess water thoroughly drains out after watering.

String Of Bananas Propagation
It’s fast and easy to propagate a String of Bananas by stem cuttings. I won’t go into detail about this here because a post and video are dedicated to propagating this plant below.

String Of Bananas Pests
Mine has never gotten any infestations, but they can be susceptible to spider mites, aphids, mealybugs, and scale insects. Be sure to click on the links below so you can identify them and see the methods of control.

String Of Bananas Toxicity
I’m not 100% sure of this because String Of Bananas isn’t on the ASPCA list. Because they’re related to String Of Pearls which are considered toxic, I’d say this one is too.
If your pets are prone to chewing on plants, keep them out of their reach. It’s easy to do with this plant because you can hang it or place it on a bookcase or shelf.
String Of Bananas Flowers
Yes, it flowers! The white flowers are borne on long stems which curve slightly upwards. They aren’t as fragrant as the String Of Pearls flowers but are pretty nonetheless. The bloom time here in winter, as it is for many succulents. The shorter days and cooler evenings play into this.
My String Of Bananas never flowered indoors, but it does every year outdoors.
String of Bananas Outdoors
If you live in a cold climate, your String of Bananas would greatly appreciate a summer vacation in the great outdoors. Everything I’ve written above applies except for three things I want to point out:
1.) Make sure it doesn’t get any strong, direct sun. The full sun will burn in no time flat, so partial shade is best.
2.) If you get a lot of rain over the summer months, you might consider placing yours under protection. A covered patio or screened porch would be fine. If a String Of Bananas gets too wet and doesn’t dry out, it’s subject to rot, and the stems and bananas (the leaves) will turn to mush.
3.) When you bring your SOBs back inside for the cold months, give it a good hosing down (gently – not like a firehose blast) to knock off any hitchhiking pests and/or their eggs.

String Of Bananas FAQs
When growing indoors, Sting Of Bananas needs a medium to high exposure. Bright indirect light is best. Too much direct sun will cause sunburn, so keep it out of hot windows.
If yours isn’t growing, the most likely cause is insufficient light. It probably needs to be moved to a place in your home with higher light exposure. If the temps are too cool, plants don’t grow as much. Warm weather and higher temps stimulate growth.
If in the right conditions, a String Of Bananas plant is an easy-to-care-for hanging succulent.
Keep your plant out of hot windows or cold windows. It can be near but not in a west-facing or south-facing window.
It can be grown indoors or outdoors year-round in a temperate climate. When growing outdoors, be sure it doesn’t get any strong, direct sun exposure.
A String Of Bananas can grow to great lengths. I saw one growing in San Diego with 7′ trails.
Also, many people don’t know this plant flowers.
String Of Pearls is a darling of houseplant lovers. Both have the same genus (Curio, formerly Senecio), but a SOPs has thinner stems. The SOPs have round leaves, whereas the SOBs have banana-shaped leaves. Other similar succulents include String Of Fishhooks, String Of Dolphins, String Of Hearts, and String Of Turtles. This post on Growing A String Of Pearls Indoors will give you an idea of what one looks like.
Conclusion: These are the 2 of the most common issues people have with String of Bananas care indoors – not enough light and overwatering. Either of these or especially a combo, will lead to the decline of your beautiful hanging succulent.

I have one indoors currently and it has four flowers, they haven’t bloomed yet but are close
Erin – Mine has been flowering since January but it’s currently growing outdoors. Nell
Mine is strictly indoors and is a prolific grower and flowerer. Just like the string of pearls, the little white flowers smell like cinnamon!
Samantha – Mine flowered profusely this year too. So sweet! Nell
I live in a dry climate and with my first SOB, the “bananas” grew thinner and thinner. I just bought a second one and would like to keep it as healthy as possible. Any tips on keeping the bananas full size?
Hi – I live in the desert & my SOBs grows outside. If the bananas get thin, it’s usually due to a lack of light or lack of water. Nell
I just got my string of bananas & I left a regular light on, and the top my bananas, the new growth look like it was burnt ?.
Help will it come back ??
Hi Shirlene – It’s hard to tell without seeing it. It depends on how badly it’s burned. Nell
I found my String of Bananas at my local farmer’s market. I never heard of them before but I thought they were so cute! My SOBs were in a hanging basket under my tree. It didn’t get a lot of direct sunlight so it did really well there. We also didn’t get very much rain this summer. Now its inside and the bananas are shriveling. I read from your post to not put it above a register vent. Well that’s where I put it. So I moved it to a different room. I hope it has enough light and hopefully it was the register!
Yes, it’ best to keep it away from any heating or cooling vents. Shriveling bananas are commonly due to lack of water at some point. Now that we’re going into winter, be sure not to water it too often. The balance between too little & too much water is often hard to balance out! Nell
