Soil Requirements
Othonna cacalioides L.f. grows well in well-draining soil. It needs soil that can retain some moisture but does not accumulate water. The soil should be loose and not compacted. A mixture of cactus soil and perlite is ideal for this plant. Furthermore, it prefers slightly acidic to neutral soil with a pH range of 6.0-7.0.
Cultivation Methods
Othonna cacalioides L.f. is a plant that grows well in warm climates and requires plenty of sunlight. It can be grown either in ground beds or pots, and it prefers well-draining soil. You can mix sand with the soil if the drainage is poor. The seeds should be sown in the early spring, and the young plants transplanted to their permanent locations in the fall.
Watering Needs
This plant prefers to be kept moderately moist, with the soil being allowed to dry somewhat between watering. However, excessive watering can cause the roots to rot, so be careful not to overwater. If you grow your plant in a pot, make sure the pot has drainage holes.
Fertilization

Pruning
You should prune your Othonna cacalioides L.f. plant to maintain its shape and size. Pinch off the tips of the stems to encourage bushy growth, and remove any dead or damaged foliage.

Propagation of Othonna cacalioides L.f.
Othonna cacalioides L.f. can be propagated through several methods, including seeding and stem cuttings. Each method has its own advantages and disadvantages.
Seeding
Seeding is a common method of propagation for Othonna cacalioides L.f. It is relatively easy and inexpensive. The seeds need to be collected from mature plants and sown in a mix of soil and sand. They should be kept in a warm, humid place until they germinate. Once the seedlings have emerged, they can be transplanted to individual pots and grown until they are large enough to be planted in the ground.
Stem Cuttings
Stem cuttings are another common method of propagation for Othonna cacalioides L.f. This method is especially useful if you want to propagate a specific plant that has desirable traits. To propagate via stem cuttings, take a stem cutting that is about 10cm long and has several leaves. Remove the leaves from the bottom half of the stem, and dip the cut end in rooting hormone to encourage root growth. Next, plant the cutting in a mix of soil and sand. It should be kept in a warm, humid place until it sprouts roots and new growth. Once rooted, the cutting can be transplanted to its permanent location.
Tips for Successful Propagation
Regardless of the propagation method used, there are a few tips you can follow to increase your chances of success. When collecting seed, choose the best-looking seeds from the plant. When taking stem cuttings, use healthy, disease-free stems. Keep the soil and cuttings moist, but not waterlogged. Provide bright, but indirect, sunlight. Mist the plants regularly to increase humidity. Finally, be patient - successful propagation can take several weeks to several months.
