Cultivation Methods
Cotyledon ventricosa Burm.f. var. alpina Harv. is a succulent plant native to South Africa. It can easily be propagated from stem or leaf cuttings. It is best grown in well-draining soil mixtures, which should not retain water for an extended period. The plant prefers bright, indirect light and should be placed in a location that receives at least 6 hours of sunlight. It can be grown both indoors and outdoors, depending on the climatic conditions in your area.
Watering Needs
Cotyledon ventricosa Burm.f. var. alpina Harv. is a drought-resistant plant and is well-suited for dry climates. It should be watered sparingly, and the soil should be allowed to dry completely between watering. Overwatering can lead to root rot and other diseases.
Fertilization

Pruning should be done in spring or early summer, using clean, sharp tools. Prune to remove excess growth or to shape the plant as desired.
Propagation of Cotyledon ventricosa Burm.f. var. alpina Harv.
The Cotyledon ventricosa Burm.f. var. alpina Harv., commonly known as 'Pig's Ear Plant' is a succulent plant that can be propagated in various ways. Here are some of the plant's propagation methods:
Propagation through Leaf Cuttings
One of the simplest and most effective ways of propagating the Pig's Ear Plant is through leaf cuttings. For this, select a healthy leaf, ideally from the outer whorl, and make a clean cut through the stem. Allow the leaf cutting to dry for a couple of days before placing it on top of well-draining soil. Mist the soil occasionally and keep it moist until new roots sprout. Once new roots develop, the plant can be transplanted into a well-draining planter.
Propagation through Stem Cuttings
Another effective way to propagate the Pig's Ear Plant is through stem cuttings. For this, select a healthy stem, ideally one that has no flowers or buds, and cut it into several sections. Allow the stem cuttings to dry for a couple of days before placing them into the soil. Mist the soil occasionally and keep it moist until new roots sprout. Once new roots develop, the plant can be transplanted into a well-draining planter.
Propagation through Seeds
The Pig's Ear Plant can also be propagated through seeds, although this method is more time-consuming and requires more patience. Sow the seeds in a well-draining soil mixture, lightly cover with soil, and gently water. Keep the soil moist but not wet and place the container in a well-lit location with indirect sunlight. The seeds should germinate within a couple of weeks, and once they have grown two or three sets of leaves, they can be transplanted into a well-draining planter.
Regardless of the method chosen, it is important to ensure that the soil is well-draining and that the plant receives the required amount of sunlight. With proper care, the Pig's Ear Plant can grow quite quickly, making it a great addition to any indoor or outdoor garden.
