Soil

Requires well-draining soil with moderate moisture retention. Adding compost or organic matter enhances soil quality.

Fertilization

Apply liquid fertilizer every two weeks during the growing season to promote flowering. Avoid over-fertilization.

Pruning

Trim overgrown vines to maintain a neat appearance and encourage new growth.

Cold Protection

Sensitive to cold temperatures; move potted plants indoors or provide insulation during winter.
