Water: Johnsons spider flower thrives with supplemental watering in dry conditions, especially for optimal growth and flowering. Initial watering should be twice a week for 2-3 weeks, then once weekly for a month, with adjustments based on local weather as it matures.

Fertilize: After planting your johnsons spider flower, no immediate feeding is necessary due to existing nutrients. Wait for warmer months to use a low-phosphorous fertilizer, as johnsons spider flower is adapted to thrive in low-phosphorous soil conditions.

Pruning: Johnsons spider flower benefits from pruning, ideally in spring, which may sacrifice some flowers but encourages abundant blooms and new growth. Pruning can also be done during warmer months to maintain a desired shape or size.

Propagation: Johnsons spider flower can be propagated via seeds, cuttings, or grafts, with soft tip cuttings being the easiest. Cuttings should be 10 cm long, taken in winter or early spring, treated with rooting hormone, and placed in sand or pumice, requiring sparse watering in a warm, shaded area. Rooting may take up to 6 months.
