Planting & Care Guide

Ideal Location

Select a location that receives at least 6 hours of direct sunlight daily. Ensure the site has well-drained soil, preferably loamy and rich in organic matter. A slightly alkaline to neutral pH (6.5–7.5) is optimal. Protect young plants from strong winds to prevent stem damage.

Watering

Water regularly during dry periods to keep the soil evenly moist but avoid waterlogging. Apply a 5 cm layer of organic mulch around the base to conserve moisture and regulate soil temperature. Adjust frequency based on rainfall and soil texture.

Pruning & Maintenance

Deadhead spent blooms to encourage prolonged flowering and reduce unwanted self-seeding. In autumn, cut stems back to ground level once foliage yellows and apply a 2–3 cm mulch. Monitor for common pests like rust and treat promptly. Fertilize lightly in spring with a balanced formulation.
