A mixture of sandy and loamy soil with the addition of perlite or pumice to improve drainage is ideal for this plant. The soil should be kept moist but not waterlogged as it may lead to root rot. Therefore, it's advisable to let the soil dry out slightly before watering.
Cultivation
The Cotyledon decussata Sims var. dielsii Schltr. ex Poelln. plant is suitable for cultivation in containers. If you live in a climate where the temperature drops below freezing, you should consider growing this plant indoors as a houseplant. If you plan to grow your plant outdoors, it should be potted in a well-draining soil mix that contains perlite or sand.

Watering Needs
The Cotyledon decussata Sims var. dielsii Schltr. ex Poelln. plant requires watering when the soil is dry to the touch. Overwatering can lead to root rot and other fungal diseases, so it's essential to let the soil dry out before watering your plant. When you water the plant, it's best to water the soil rather than the leaves, as this can cause water damage and discoloration to the leaves.
Fertilization
During the growing season, the Cotyledon decussata Sims var. dielsii Schltr. ex Poelln. plant requires regular fertilization. Fertilize the plant every three to four weeks using a balanced fertilizer mix that is diluted to half the recommended strength. These nutrients will help the plant grow and produce healthy leaves and flowers.
Pruning
If you want to control the size and shape of your Cotyledon decussata Sims var. dielsii Schltr. ex Poelln. plant, you can prune it regularly. Prune the stems at the base of the plant or where it meets the soil. Be careful not to overprune the plant, as this can stunt its growth and weaken its ability to produce flowers.
Propagation of Cotyledon Decussata Sims var. Dielsii Schltr. ex Poelln.
Cotyledon Decussata Sims var. Dielsii Schltr. ex Poelln., or more commonly known as the Paddle Plant, is a succulent that can be propagated through various methods.
Leaf Propagation
One way to propagate the Paddle Plant is through leaf propagation. Simply cut a leaf cleanly from the plant and place it on a well-draining soil mix. It is essential to let the cut edge callus over for a few days before planting it. The new plant will root within a month or two. Like most succulents, it is essential to avoid overwatering and keep the soil moist, but not soggy.
Stem Propagation
Another way to propagate the Paddle Plant is through stem cuttings. Using a sharp and sterilized knife, cut a stem from the parent plant, making sure it is about 10-15 cm long. Remove lower leaves from the stem, leaving only two or three at the top intact. Leave the cutting to dry out for a few days until the cut end forms a callous before placing it on the soil. Like leaf propagation, it is essential to keep the soil moist but not waterlogged and place it in a shaded area until rooting occurs. The cuttings will root within a few weeks.
Division
The Paddle Plant can also propagate through division when the plant has grown too big or starts developing offsets. Gently remove the plant from its pot and divide the offsets from the main plant. Repot and treat them as individual plants.
Propagation of the Paddle Plant is relatively easy and can make a stunning addition to any garden or collection. Following the propagation methods carefully can ensure the successful growth of these beautiful succulents.
