Gardening Tips

Cat’s Whiskers prefers warm climates and grows well in sunny, well-ventilated places. Please keep the following points in mind:

Sunlight

Plant it in a sunny location. It can also grow in partial shade, though flowering may be reduced.

Watering

Water thoroughly when the soil surface dries. In summer, consider watering twice daily (morning and evening), as the soil tends to dry quickly. Avoid overwatering and ensure good drainage.

Soil

Well-drained soil is best. For pots, use a flowering plant soil mix with added perlite. For ground planting, mix leaf mold into the soil to improve drainage.

Fertilizer

During the growing season (spring to autumn), apply a slow-release fertilizer once or twice a month. Avoid over-fertilizing and follow instructions carefully.

Pruning

After flowering, cut back the flower stems to encourage the next bloom. Trim overly long branches for a tidy appearance.

Cold Tolerance

As it is weak against cold, bring it indoors or provide frost protection when temperatures drop. Aim to keep it above 5°C during winter.
