It is a low-maintenance plant that can be grown in various soil types, including poor soil, as long as it is well-draining. The plant prefers full sunlight and can tolerate partial shade. It can be propagated through seeds, and it is advisable to sow the seeds directly into the ground as the plant does not transplant well.
Watering Needs
The plant is drought-tolerant and does not require frequent watering. However, during the initial growth stage, the plant requires regular watering until it establishes itself. After that, the plant can survive on rainfall water alone. It is advisable to avoid overwatering the plant as it can cause root rot.

Propagation of Platyschkuhria integrifolia var. desertorum
Platyschkuhria integrifolia var. desertorum can be propagated through either seeds or stem cuttings.
Propagation by seeds
The ideal time to collect seeds from Platyschkuhria integrifolia var. desertorum is in the summer months. The seeds must be sown immediately after collection. Before sowing, the seeds need cold stratification for at least four weeks. This process can be achieved by keeping the seeds in a refrigerator at 40°F to 45°F.
The seeds can be sown in pots or directly in the ground. In the case of sowing in pots, the pots must be filled with well-draining soil. The seeds should be covered with a thin layer of soil and kept moist until germination, which can take up to three weeks. Once the seedlings reach a height of 4-5 inches, they can be transplanted into bigger pots or directly into the ground.
Propagation by stem cuttings
Stem cuttings can be taken at any time during the growing season of Platyschkuhria integrifolia var. desertorum. The cuttings should be taken from new growth and be around 3-4 inches in length. The lower leaves on the stem must be removed, and the cutting must be dipped in rooting hormone powder.
The stem cuttings can be planted in pots filled with well-draining soil. The pots must be kept in a warm, humid environment, with temperatures between 70°F to 80°F. The soil must be kept moist at all times. Once roots have developed, the cuttings can be transplanted into bigger pots or directly into the ground.

While this plant is generally quite resilient, it can still fall prey to a number of pests and diseases. Here are some of the most common problems that can affect Platyschkuhria integrifolia, along with tips for managing them:
Pests
Aphids: Aphids are tiny insects that suck sap from plant leaves, causing them to yellow and wilt. Infestations can weaken the plant and make it more vulnerable to disease. To manage aphids, regularly inspect the plant and remove any affected leaves or stems. Use a stream of water to dislodge any remaining aphids. You can also introduce beneficial insects like ladybugs and lacewings to help control the aphid population.
Mites: Mites are another pest that can damage Platyschkuhria integrifolia. They feed on the plant's leaves and can cause them to turn yellow or brown and drop prematurely. To manage mite infestations, use a miticide spray or release predatory mites to control the population.
Diseases
Root Rot: Root rot is caused by a fungus that thrives in wet and poorly drained soil. It can cause the plant's roots to rot, leading to stunted growth and wilting. To manage root rot, ensure that the plant is not overwatered and that it is planted in well-draining soil. You can also treat the plant with a fungicide.
Powdery Mildew: Powdery mildew is a fungal disease that creates a white or gray powdery coating on the leaves of the plant. It can cause the leaves to curl and the plant to become stunted. To manage powdery mildew, remove infected leaves and provide good air circulation around the plant. You can also treat the plant with a fungicide.
Leaf Spot: Leaf spot is a fungal disease that causes brown or black spots to appear on the leaves of the plant. It can cause the leaves to yellow and drop prematurely. To manage leaf spot, remove infected leaves and provide good air circulation around the plant. You can also treat the plant with a fungicide.
No matter what pest or disease is affecting your Platyschkuhria integrifolia, it's important to act quickly to minimize the damage and prevent it from spreading to other plants in your garden. Regular inspections and proper care are key to keeping your Mojave desert-daisy healthy and strong.
