Fertilizing Balanced liquid fertilizer (10-10-10) diluted to half strength, every 4-6 weeks during the growing season.
Seasonal Care Spring: Plant outdoors after the last frost. Summer: Provide regular watering and fertilization. Fall: Divide established clumps. Winter: Reduce watering and provide protection from frost.

Creeping Jenny

Repotting Every 1-2 years, or as needed when the plant becomes root-bound. Repot into a slightly larger container.
Pruning Prune regularly to maintain shape and encourage bushier growth. Trim back any leggy or overgrown stems.
Fertilizing Balanced liquid fertilizer (10-10-10) diluted to half strength, every 4-6 weeks during the growing season (spring and summer).
Seasonal Care In winter, reduce watering and withhold fertilizer. Ensure adequate light. In summer, provide consistent moisture and fertilize regularly.

💧 Watering Needs

Balloon Flower

Water thoroughly when the top inch of soil feels dry. Avoid overwatering, which can lead to root rot. Ensure good drainage. Reduce watering frequency during dormancy in winter. Signs of overwatering include yellowing leaves and soggy soil. Underwatering results in wilting and dry, crispy leaves.

Creeping Jenny

Keep the soil consistently moist, but not waterlogged. Allow the top inch of soil to dry out slightly between waterings. Overwatering can lead to root rot, while underwatering will cause the leaves to wilt and turn brown. Ensure good drainage.
