Care Guide
Water
Petrophile plants prefer well-draining soil and do not like to be overwatered. They should be watered deeply once a week during the growing season, and less frequently during the winter months. It is important to avoid getting water on the leaves, as this can lead to fungal infections.
Fertilization
Petrophile plants do not require a lot of fertilization. A slow-release fertilizer can be applied in the spring, but it is important to avoid over-fertilizing, as this can lead to excessive growth and weak stems.
Soil
Petrophile plants prefer well-draining soil that is slightly acidic. They do not like to be planted in heavy clay soils, as this can lead to root rot.
Sunlight
Petrophile plants prefer full sun to partial shade. They will not thrive in deep shade, as they require plenty of sunlight to produce flowers.
Hardiness Zones
Petrophile plants are generally hardy in USDA zones 8-10, but this can vary depending on the species.
Common Pests & Diseases
Petrophile plants are generally quite hardy and are not prone to many pests or diseases. However, they can be susceptible to root rot if they are planted in heavy clay soils that do not drain well. They can also be affected by fungal infections if they are overwatered or if water is allowed to sit on the leaves.
Habitat
Petrophile plants are endemic to Australia and can be found growing in a variety of habitats, including heathlands, woodlands, and forests. They are particularly common in the southwest region of Western Australia.
