🌱 How to Care for Autumn Joy Sedum to Prevent Aphids?

💧 How to Water

Water deeply but infrequently — once every 14 days during the growing season is sufficient. Allow the soil to dry out completely between waterings. Overwatering is the most common mistake; these plants are succulents and store water in their leaves and stems. Reduce watering to near zero in winter when the plant is dormant.

☀️ Lighting

Hylotelephium requires full sun — at least 6 hours of direct sunlight per day. In too much shade, stems become weak and floppy, a condition called etiolation. A south- or west-facing garden bed is ideal. The more sun the plant receives, the more compact and floriferous it will be.

🪴 Ideal Soil

Plant in well-draining soil — sandy, loamy, or gravelly substrates are ideal. Avoid heavy clay or consistently moist soils, which can cause root rot. If your soil is heavy, amend it with coarse grit or perlite before planting. Raised beds are an excellent option for improving drainage in problem areas.
