Senecio mikanioides also called German Ivy, Cape Ivy or Parlour Ivy is among the fast-growing, climbing Senecio varieties and bears fleshy, glossy, lobed leaves and clusters of bright yellow daisy-like flowers.
Though called an ivy, Senecio mikanioides is not a True Ivy as it is more vigorous and is less affected by warm and dry conditions than a true ivy. The German Ivy leaf lobes are fleshier and generally more pointed and the leaves have several pointed lobes.
Cape Ivy stems like those for Scrambling Groundsel (Senecio angulatus), can be allowed to hang downwards in a hanging basket or trained up a moss pole or a trellis.
Parlour Ivy growth can be controlled by regular pinching of the growing tips to encourage a bushy growth and to prevent it from becoming unruly.

How to care for Senecio mikanioides indoors
To care for German Ivy indoors, give it medium to bright indirect light, warmth of 18-270C, humidity of 50-55% and moderately moist, rich, well-drained soil coupled with fortnightly feeding in the growing season.
Senecio mikanioides requires pruning to keep the plant neat, to reduce pest and disease infestations, to encourage a bushy, compact growth and to rejuvenate growth. Repotting is only needed every 2-3 years when pot-bound. Keep reading for more on these growing conditions and how to achieve them.
Watering
Water German Ivy thoroughly in spring and summer while allowing the top 2-3 inches of soil to dry out between waterings. Maintain the soil moderately moist and avoid overwatering to prevent rotting, drooping and yellowing leaves, and leaf loss.
Decrease watering in fall and winter as growth is minimal at this time. Do not allow the soil to dry out completely for a prolonged period as it can lead to browning, drooping, wilting and leaf drop.
Use water that is at room temperature to prevent cold shock which can result in stunted growth and leaf drop. Only water with chlorine-free water like rainwater to prevent browning of leaf edges.
Make sure that the soil is free-draining and the pot has a drainage hole to prevent waterlogging which can lead to rotting and death of the plant. Avoid wetting the foliage to discourage fungal diseases.
Light Requirements
Does German Ivy like sun or shade?
German Ivy thrives in medium to bright indirect light (dappled light); put in near a large, bright, sunless window. Keep it away from direct sunlight to avoid scorching; crispy edges and brown marks on the leaves.
Too little light will result in slow growth with leaves becoming pale and sparsely spaced (leggy growth). Therefore, use a grow light if the natural light is insufficient.
Once monthly, give the pot a quarter turn to ensure that the plant receives light on all sides for uniform growth to prevent legginess.
Temperature & Humidity
Senecio German Ivy prefers a warmth of 18-270C; a temperature that is comfortable for you is ideal for this plant. Keep it away from sources of drafts to prevent sudden changes in temperatures which can cause reduced growth, wilting, drooping, yellowing and sudden leaf drop.
Parlour Ivy has no need for extra humidity; a humidity of 50-55% is adequate for this plant. However, too low humidity can result in brown leaf tips and edges. To increase humidity, set the pot on a wet pebble tray or use a humidifier. Ascertain there is good air circulation to prevent fungal diseases.
Fertilizer
Feed German Ivy with a balanced, water-soluble fertilizer every 2-3 weeks in spring and summer to enhance growth. Withhold fertilizer in the cold season as growth is reduced at this time and feeding at this time can lead to fertilizer burn.
Potting Soil
The best potting mix for Senecio German Ivy is cactus and succulents mix as the plant is prone to root-rot which is prevalent in poorly drained soil. A Cactus and succulents mix is perfect for this plant as it is loose enough, drains easily and does not get soggy.
Repotting
Repot Cape Ivy every 2-3 years during the growing period, only when pot-bound. Use a pot 1 size larger that has a drainage hole to prevent rotting. Check out these succulents pots on Amazon.
Pruning and Grooming
Pruning German Ivy involves:
- Removal of yellow and dead leaves to maintain the plant neat and also discourage pest and disease infestations.
- Pinch off the growing tips to encourage a bushy and compact growth. You may choose to use the tips to propagate new plants.
- Cutting back the leggy stems with a sharp, clean pair of pruning scissors to rejuvenate growth and encourage a bushy growth.
Occasionally clean the leaves under a stream of running water to get rid of dust and discourage pest infestation.
German Ivy Propagation
Senecio mikanioides propagatation is best done at the beginning of the growing season from the stems which can be rooted in 3 easy ways. The stems root easily so there is no need for a rooting hormone. Learn how to propagate German Ivy (Senecio mikanioides).
Senecio mikanioides Problems & Remedies
German Ivy problems are brown leaves, wilting leaves, black leaves, yellow leaves, leggy growth, pests and diseases among others. Keep reading for more on these problems and their solutions.
Brown leaves
Why are the leaves on my German Ivy turning brown?
The main causes of brown leaves on your German Ivy are low humidity, underwatering, temperature stress or direct sunlight.
How to fix it
Low humidity: Set the pot on a wet pebble tray, group the plants together or grow the plant in a well-lit bathroom or laundry area.
Underwatering: Water when the top 2-3 inches of soil dry. Never allow the soil to dry out completely.
Direct sunlight: Keep the plant away from direct sunlight or instal a light curtain or sheer to filter the sun.
Temperature stress: Keep the plant away from drafts like windy doors, drafty windows, air conditioning units, heat sources among others.
Wilting leaves
Why is my German Ivy wilting?
Your German Ivy is wilting due to underwatering, direct sunlight or high temperatures.
How to fix it
Underwatering: Water the plant immediately it starts to droop and it should perk up. Do not allow the soil to dry out completely.
Direct sunlight: Avoid exposing the plant to direct sunlight. Give it bright indirect light.
High temperatures: Keep the plant away from hot drafts coming from AC units, heat vents, stoves and other heat sources.
Black leaves
Why are the leaves on my German Ivy turning black?
The leaves on your German Ivy are turning black due to root-rot which is prevalent in soggy soil.
How to fix it
- Carefully, slip the plant out of its pot and inspect the roots.
- Brown-black mushy roots indicate root-rot, trim them off and treat the healthy roots with a copper-based fungicidal solution.
- Disinfect the pot with the fungicidal solution or use a fresh pot to repot the plant in fresh free-draining soil.
- Withhold watering and keep the plant dry for 5-7 days before you resume watering.
- To prevent root-rot in the future, use a pot with a drainage hole and well-drained soil.
- Avoid overwatering in the cold season as growth is minimal at this time, therefore, the plant does not require much water.
Yellow leaves
Some of the causes of yellow leaves on German Ivy are inconsistent watering, soggy soil or too little light.
How to fix it
Inconsistent watering: Do not water on a schedule; water the plant when the top 2 inches of soil dry but do not allow the soil to dry out completely for too long.
Soggy soil: Use well-draining soil and a pot that has a drainage hole.
Too little light: Position the plant in bright indirect light or use a grow light is the natural light is not enough.
Leggy growth
Leggy growth on German Ivy is caused by too little light. Move the plant to a brighter spot or instal a grow light if the natural light is not adequate.
