🌱 How to Care for Astragalus to Prevent Aphids?

💧 How to Water

Water deeply, but only when the soil has completely dried out. Avoid constant moisture, as Astragalus is extremely susceptible to root rot. For established plants, watering every 1-2 weeks during dry periods is sufficient.

☀️ Lighting

Full sun is optimal: at least 6-8 hours of direct sunlight daily. It can also tolerate partial shade, but root development and the content of medicinal compounds will be reduced. During hot summers, afternoon shade can protect it from heat stress.

🪴 Ideal Soil

It prefers well-draining, sandy or sandy-loam soil with a neutral to slightly alkaline pH (6.5-7.5). Clayey, wet soil causes root rot. If necessary, it can be grown in raised beds or in soil amended with sand and compost.
