Growing Information:
Light: The American High-Bush Cranberry thrives in full sun to partial shade. For best berry production, it’s ideal to plant it in an area that receives at least 6 hours of direct sunlight each day.
Soil: These shrubs prefer acidic, well-draining soil with a pH of 4.5–5.5. While they can tolerate a range of soil types, they thrive best in slightly acidic, moist soils.
Planting Tips:

- Transplant seedlings to larger containers once they are large enough to handle, or directly into the garden after all danger of frost has passed. Space plants 4–5 feet apart to give them room to grow.
Watering: Keep the soil consistently moist, especially during dry periods. Mulching around the base of the plant can help retain moisture and keep roots cool. Ensure the area around the roots has good drainage to prevent root rot.
