Care Guide

Stackhousia plants are relatively easy to care for, and they require moderate attention. Here are some care tips:

• Water: Stackhousia plants require regular watering, especially during the hot summer months. However, make sure the soil is well-drained to prevent root rot.
• Fertilization: Apply a balanced, slow-release fertilizer during the growing season to promote healthy growth and flowering.
• Soil: Stackhousia plants prefer well-draining soil that is slightly acidic. Amend the soil with organic matter to improve its fertility and drainage.
• Sunlight: Stackhousia plants need full sun to partial shade to thrive. Make sure they receive at least 6 hours of direct sunlight per day.
• Hardiness Zones: Stackhousia plants are hardy in USDA zones 9-11 but can also grow in other zones with proper care.

Common Pests & Diseases

Stackhousia plants are generally pest and disease-resistant, but they can still be affected by some common issues. Here are some of them:

• Spider Mites: These tiny pests can cause yellowing and wilting of leaves. Use insecticidal soap or horticultural oil to control them.
• Scale Insects: These pests attach themselves to the stems and leaves of the plant and suck the sap. Use neem oil or a systemic insecticide to control them.
• Root Rot: Over-watering or poorly-drained soil can cause root rot in Stackhousia plants. Use well-draining soil and avoid over-watering to prevent this issue.

Stackhousia plants are native to various regions of Australia, including Western Australia, South Australia, and New South Wales. They grow in a variety of habitats, including woodlands, heathlands, and shrublands. Some species of Stackhousia are endangered due to habitat loss and over-collection for horticultural purposes.
