Some links in this post may be affiliate links
String of Bananas Plant (Senecio radicans) flourishes in bright light with some direct sunlight, average warmth, moderate humidity and moderately moist, rich, well drained, succulents soil coupled with monthly feeding in the growing season.
Senecio radicans also called String of Fishhooks Plant or Fishhooks Senecio is one of the popular Senecio varieties and bears pendant thread-like stems on which are tiny leaves shaped like small green bananas.
The odd shaped leaves is an adaptation to arid conditions and allows for the storage of water while exposing minimum surface area to the dry desert air which greatly reduces water loss.
The fleshy leaves and stems store water, which allows the plant to go for a considerably long period without being watered. String of Bananas Plant is one of the best plants with low water needs.
String of Fishhooks Plant leaves bear a translucent window that runs the length of the leaf which allows light to reach into interior of the leaf where photosynthesis takes place.
Fishhooks Senecio in its natural habitat, grows as a trailer, with stems trailing on the ground, rooting where they touch and forming dense mats. It is one of the favorite String of plants for indoors.
This growth habit makes the plant perfect for a hanging basket, a pedestal, a tabletop or a plant shelf where the stems can beautifully cascade downwards placing this plant among the hanging succulent plants for any space.
On account of its drought tolerance and requirement for bright light with exposure to some direct sunshine, String of Bananas Plant is one of best succulent plants for full sun ideal for a sunny location.

Senecio radicans Care Indoors
String of Bananas Plant (Senecio radicans) thrives in bright light with 6-8 hours of direct sunlight, average warmth of 20-270C, moderate humidity of 50-55% and moderately moist, rich, well drained, succulents potting soil coupled with monthly feeding during the growing season.
Curio radicans requires pruning to keep the plant neat, to reduce pest and disease infestations and rejuvenate growth. Repotting is only needed when the plant has become root-bound. Keep reading for more on these growing conditions and how to achieve them.
Light Requirements
String of Bananas Plant grows best in bright light with at least 6-8 hours of morning or late afternoon sunlight per day. Keep it away from hot midday sunshine to prevent scorching and loss of leaf color.
Inadequate light for String of Fishhooks Plant will result in a leggy plant and the banana-like leaves will be sparsely spaced. Therefore, if the natural light is not sufficient, you may grow the plant under a grow light. Check out these full spectrum grow lights on Amazon.
Turn the pot regularly to make sure that the plant receives light on all sides for uniform growth as well as avoid leggy growth and leaf drop.
Watering
Water String of Bananas Plant liberally during the growing season while allowing the top 2-3 inches of soil to dry out between waterings to maintain the soil moderately moist.
Cut down on watering in the cold period to maintain the soil barely moist but do not allow the soil to dry out completely as it can lead to wilting and leaf drop.
Make sure that the pot has a drainage hole inorder to prevent the soil from getting soggy as it can lead in rotting and eventual death of the plant.
Temperature and Humidity
Average warmth of 20-270C is ideal for String of Bananas Plant. A room temperature that is comfortable for you is ideal for this plant. Keep it away from drafts as it does not like sudden changes in the temperature as they can cause stunted growth and leaf drop.
String of Bananas Plant has no need for high humidity. Average room humidity of 50-55% is ideal for the plant. However, ensure that there is good air circulation to prevent fungal diseases infestation.
Feeding
Feed Senecio radicans monthly during the growing season with a balanced, liquid fertilizer. This plant is not a heavy feeder so be careful when feeding.
Withhold fertilizer in the cold season as growth is minimal at this time and feeding at this time can cause fertilizer burn and eventual death of the plant.
Potting Medium
The best potting medium for String of Bananas Plant should be rich in organic matter, loose and free-draining to avoid getting soggy soil. The soil should be loose enough to allow water to drain out fast enough. Cactus and succulents mix is ideal as they drain easily.
Repotting
String of Bananas Plant has a small root system so frequent repotting is not necessary. Repot it at the beginning of the growing season only when it becomes crowded in its current pot.
Use a pot that is only 1 size larger than the current one and one that has a drainage hole to prevent the soil from getting soggy as it can lead to rotting. Use a shallow pot and be careful not to bury the stems of the plant to prevent rotting. Check out these succulents pots available on Amazon.
Pruning
Pruning Curio radicans involves removal of any dead leaves and stems to keep the plant neat and also discourage pest and disease infestations. Trim the stems if they become too long or straggly to rejuvenate growth.
Propagation
String of Bananas Plant (Senecio radicans) can be propagated at the beginning of the growing season from stem cuttings.
How to propagate String of Bananas Plant from stem cuttings
Take 3-5 inches stem cuttings from a healthy String of Bananas Plant and allow the cuttings to dry (callus) for about 7 days.
Lay the stems on moist free-draining soil and lightly press the stems into the soil at the nodes.
Place the set up in a warm, well-lit place and maintain the soil moist until the stems are rooted.
Allow substancial growth before transplanting the new Curio radicans after which routine care can begin.
Senecio radicans Problems and Remedies
String of Bananas Plant (Senecio radicans) growing problems include leaf drop, leggy growth, leaf spots, rotting, plant death, pests and diseases among others. Keep reading for more on these problems and how to fix them.
Diseases
String of Bananas Plant is prone to powdery mildew. Isolate the affected plant to prevent spread to other plants and treat it for the disease.
Pests
The common pests in String of Bananas Plant are spider mites, scale insects and mealy bugs. Isolate the affected plant to prevent spread to other plants and treat it for the pests. Learn how to identify and get rid of pests in houseplants.
Brown, soft leaf spots
Brown, soft leaf spots in String of Bananas Plant are an indication of leaf spot disease. Avoid wetting the leaves and improve air circulation to prevent disease infestations.
Rotting base, stem collapse
Rotting plant base and stems collapse in String of Bananas Plant is an indication of basal stem-rot disease which is brought about by overwet conditions. Use the upper healthy stems to propagate new plants and discard the infected parts to reduce spread to the rest of the plant.
Thereafter, water the plant liberally during the growing season while allowing the top 2-3 inches of the soil to dry out between waterings. Significantly reduce watering during the cold season to maintain the soil barely moist as growth is minimal at this time.
Leggy growth (elongated stems)
Leggy growth (elongated stems) in String of Bananas plant during the cold season is due to too much water (overwatering) or soggy soil. Cut down on watering during the cold season to maintain the soil barely moist and ensure that the pot has a drainage hole to prevent the soil from getting soggy.
If leggy growth (elongated stems) in String of Bananas Plant happens during the growing season, then the cause is too little light. Move the plant to a brighter spot and ensure it receives bright light with some direct sunlight of at least 4-6 hours or instal a grow light if the natural light is inadequate.
Further, regularly turn the pot to ensure that the plant receives light on all sides for even growth. Check out this guide on understanding light for houseplants.
Sudden leaf drop
There are two possible causes on sudden leaf drop in String of Bananas Plant. One possible cause is watering with very cold water. Being a tropical plant where temperatures are warm, watering with too cold water will shock the plant. Use water that is at room temperature to avoid shocking the plant.

Brown dry spots
Brown dry spots in String of Bananas Plant are due to underwatering resulting in too little moisture in the soil. Water the plant moderately during the hot season while while allowing the top 2-3 inches of the soil to dry out between waterings. Lessen watering during the cold period to maintain the soil barely moist as growth is reduced at this time.
Wilted, discolored leaves
