How to keep Ptilostemon Casabonae.

Water
Ptilostemon casabonae, which originally comes from Mediterranean climates, thrives in environments with moderate humidity and can tolerate short periods of drought. For optimal vitality, it prefers consistent moisture, so it is best to water the plant twice a week. This is particularly important during periods of peak growth to promote lush development.
Temperature
Sardinian Ivory Thistle adapts well to a wide range of climate conditions, from scorching summers to cold winters. Nevertheless, it has an optimal temperature range for growth. If temperatures become too high, the plant is susceptible to heat and humidity stress, which can cause it to die. In areas where temperatures approach the lower limit of its cold tolerance, it's important to take insulating measures to protect the plant.
Fertilizer
Fertilize your Sardinian Ivory Thistle in early spring to encourage healthy growth. Regular feeding improves overall health, leading to vigorous growth, increased resilience to harsh conditions, and better resistance to pests and diseases. Keep to a consistent fertilization schedule for your Sardinian Ivory Thistle to maintain vibrant foliage with deep color and a lush appearance.
