For the quillaja genus, well-draining soil is essential, along with full sun exposure to promote healthy growth. They prefer a semi-arid climate with moderate water requirements, avoiding overly wet conditions. Begin by prepping the site with loose soil and adequate spacing for root growth. When planting, place quillaja at the same depth as their container, firming the soil around the root ball. Water thoroughly after planting. Opt for mulching to retain moisture and provide insulation. It’s crucial to recognize that specific quillaja species may have unique requirements.
