Care Guide

Paepalanthus plants require specific care to thrive. Here are some care tips:

• Water: These plants require moist soil, but they don’t like to be waterlogged. Water them regularly, but make sure the soil has good drainage.
• Fertilization: Paepalanthus plants don’t require much fertilization, but you can use a balanced fertilizer once a month during the growing season.
• Soil: These plants prefer well-draining soil that is rich in organic matter.
• Sunlight: Paepalanthus plants prefer full sun to partial shade. They can tolerate some shade, but they won’t flower as well.
• Hardiness Zones: These plants are not frost-hardy and should be grown in zones 9-11.

Common Pests & Diseases

Paepalanthus plants are relatively pest and disease-free, but they can be susceptible to root rot if the soil is too wet. Here are some common pests and diseases:

• Root rot: This is caused by overwatering or poorly-draining soil. The plant may wilt or turn yellow and may eventually die.
• Aphids: These small insects can suck the sap from the plant, causing it to wilt and become stunted. They can be controlled with insecticidal soap.
• Spider mites: These tiny pests can cause yellowing and browning of the leaves. They can be controlled with insecticidal soap or a strong jet of water.

Habitat

Paepalanthus plants are native to South America, especially Brazil. They grow in a variety of habitats, including savannas, grasslands, and wetlands. They prefer moist soil and can tolerate some flooding, but they don’t like to be waterlogged. They are often found growing in clumps or rosettes and can be an important part of the ecosystem in these habitats.
