Some links in this post may be affiliate links
German Ivy (Senecio mikanioides) grows best in medium to bright light, moderate warmth, average humidity and moderately moist, fertile, well-drained soils coupled with fortnightly feeding during the growing season.
Senecio mikanioides is a fast growing, evergreen, climbing plant which bears fleshy, glossy, lobed leaves and clusters of bright yellow daisy-like flowers.
Though called German Ivy, Cape Ivy or Parlour 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.
German Ivy leaf lobes are fleshier and generally more pointed and the leaves have several pointed lobes.
Cape Ivy stems can be allowed to trail like in a hanging basket or are trained up canes or trellis. It is one of the best plants for a hanging basket.
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.
German Ivy like other Senecio varieties can also be grown outdoors in a sunny spot but it should be protected from hot midday sunlight.
Botanical name: Senecio mikanioides
Synonym: Delairea odorata
Family: Asteraceae

Invasiveness
According to Greater Wellington Pest and Weed Central, Senecio mikanioides has been found to be invasive. It is not recommended to be planted in the ground as given time, it will smoother trees.
To counter this invasive nature of Cape Ivy, always destroy the underground rhizomes before discarding as they easily resprout if left on the ground.

Senecio mikanioides Care Indoors
German Ivy (Senecio mikanioides) flourishes in medium to bright light, moderate warmth of 18-270C, average humidity of 50-55% and moderately moist, fertile, well-drained, all purpose soils coupled with fortnightly feeding during 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 the plant becomes pot-bound. Keep reading for more on these growing conditions and how to achieve them.
Watering
Water German Ivy thoroughly during the growing season and allow the top 2 in. of soil to dry out between waterings to maintain the soil moderately moist.
Decrease watering during the cold period as growth is minimal at this time 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 draiange hole to prevent the soil from getting soggy as it can lead to rotting and eventual death of the plant.
Light Requirements
German Ivy grows best in medium to bright light away from direct sunlight as it can cause scorching of the leaves.
Regularly turn the pot to ensure that the Cape Ivy receives light on all sides for uniform growth.
You may also grow Senecio mikanioides under grow lights where the natural light is insufficient. Check out these full spectrum grow lights available on Amazon.
Temperature and Humidity
German Ivy prefers average warmth within the range 18-270C. A room temperature that is comfortable for you is ideal for this plant.
Keep the Parlour Ivy away from drafts to prevent sudden changes in temperatures which can cause sudden leaf drop.
German Ivy has no need for high humidity. Average room humidity of 50-55% is adequate for this plant. Occasionally clean the leaves under a stream of running water to get rid of dust and discourage pest infestation.
Fertilizer
Feed German Ivy every 2-3 weeks during the growing season with a balanced, water-soluble fertilizer to enhance growth.
Withhold fertilizer during the cold season as growth is reduced at this time and feeding at this time can lead to fertilizer burn.
Potting Mix
The best potting mix for German Ivy is cactus and succulents mix as the plant is prone to root-rot which is prevalent in poorly drained soil.
Cactus and succulents soil is loose enough and drains easily, therefore, does not get soggy. Buy quality cactus and succulents potting mix from Amazon for your Cape Ivy.
Repotting
Repot German Ivy every 2-3 years during the growing period only when it becomes pot-bound. Use a pot which is 1 size larger than the current one.
Ensure that the pot has a drainage hole to prevent the soil from getting soggy as it can lead to rotting and eventual death of the plant. Check out these Ceramic Pots with Drainage Holes and Saucer on Amazon.
Pruning
Pruning German Ivy involves removal of yellow and dead leaves to maintain the plant neat and also discourage pest and disease infestations.
To encourage a bushy and compact growth, pinch off the growing tips. You may choose to use the tips to propagate new plants.
Cutback the leggy stems with a sharp, clean pair of pruning scissors to rejuvenate growth and encourage a bushy growth.
Propagation
German Ivy (Senecio mikanioides) is propagated at the beginning of the growing season from the stems. They root easily so there is no need for a rooting hormone. The stems can be rooted in 3 ways.

Senecio mikanioides Growing Problems
German Ivy (Senecio mikanioides) problems include leggy growth, curled leaves, dropping leaves, pests and diseases among others. Read on for more on these problems,their remedies and solutions.
Leggy growth and undersized (small) leaves
Leggy growth and undersized leaves in German Ivy are caused by too little light as it grows best in medium to bright light away from direct sunlight.
Move the Parlour Ivy to a brighter spot where it will receive medium to bright light or instal a grow light if the natural light is not adequate
Pests
Common pests in German Ivy are mealy bugs and aphids. Isolate the affected plant to prevent spread to other plants and treat it with neem oil or insecticidal soap as per manufacturer's instructions.
Diseases
Common diseases in German Ivy are leaf spot and root-rot which are prevalent in too wet conditions.
Isolate the affected plant to prevent spread to other houseplants and treat it appropriately for the diseases.
To reduce disease infestation, ensure that there is good air circulation for the Cape Ivy at all times.
In addition, ensure that the soil is free-draining and the pot has a drainage hole to prevent soggy soil.
Brown leaves with curled edges
Brown leaves and curled edges in German Ivy are caused by overwatering or too wet soil (soggy soil). Ensure the soil is free-draining and the pot has a drainage hole.
Water the Cape Ivy only when the top 2 in. of soil have dried out to maintain the soil moderately moist during the growing seasn.
Significantly reduce watering during the cold season to keep the soil slightly moist as growth is reduced at this time. Learn more on how to water houseplants correctly.
Drooping leaves
Drooping leaves in German Ivy are due to underwatering resulting in too little moisture in the soil.
This means that the leaves loss more water to the air than they are getting from the soil which causes them to lose their turgidity (stiffness) and thus they droop.
Water the Cape Ivy immediately it starts to droop and it should perk up. Do not allow the soil to dry out completely but only slightly before watering again.
