For the genus pharnaceum, aim for well-draining soil enriched with organic matter, providing a balance between moisture retention and drainage. Adequate sunlight, with a preference for full sun to partial shade, is vital. Water should be consistent, especially during the establishment period, without over-saturating. Start by loosening the soil, integrating compost, and ensuring proper spacing. Carefully plant without deep burying, and water thoroughly. Mulching helps retain moisture and suppress weeds. Recognize that different pharnaceum species may have varying specific requirements.
