For planting astydamia, select a well-draining soil enriched with organic matter. These plants thrive in full to partial sunlight and require moderate watering, allowing the soil to dry out slightly between irrigations. Begin by loosening the soil in the planting area and incorporating compost. Plant astydamia at the same depth they were in their nursery container, spacing them to accommodate growth. Water thoroughly after planting. Mulching helps retain moisture and suppresses weeds. Acclimatize astydamia to local conditions and monitor for pests and diseases. Specific care may vary, so research individual species' needs.
