🌱 How to Care for Glossy Abelia to Prevent Leaf Spot?

💧 How to Water

Water deeply once or twice a week during the first growing season to help roots establish, then reduce to occasional deep watering once the shrub matures. Let the top layer of soil dry slightly between waterings and avoid soggy, waterlogged soil, which can lead to root rot.

☀️ Lighting

Plant in full sun for the best flowering display, though Glossy Abelia also tolerates partial shade. Aim for at least four to six hours of direct sunlight a day; too little light results in sparse blooms and leggy growth.

🪴 Ideal Soil

Grow in loamy, sandy, or clay soil as long as drainage is good. A slightly acidic to neutral pH between 6.0 and 7.5 is ideal. Amend heavy clay with organic matter to improve drainage and reduce the risk of root rot.
