Transplanting Instructions

1. Choose a planting site with well-draining, rich soil amended with compost for nutrients and moisture retention. Ensure the area receives 4-6 hours of sunlight.
2. Dig a hole slightly wider and deeper than the 3" pot's root ball.
3. Gently remove the plant from the pot, teasing out any potbound roots to encourage growth.
4. Place the plant in the hole so the base is level with the surrounding soil.
5. Backfill with soil, tamp down lightly to eliminate air pockets, and water thoroughly.
6. Mulch around the base to retain moisture and suppress weeds. Keep soil consistently moist but not soggy, especially during the first few weeks. Space plants 6-12 inches apart for optimal growth. If planting in containers, use a high-quality potting mix and ensure good drainage.
