Sun: Elderflowers grow best in full sun to partial shade, requiring at least 6-8 hours of sunlight daily.

Watering: Keep the soil consistently moist but not waterlogged. Water regularly, especially during dry spells, to keep the soil evenly moist.

Spacing: Plant elderflower transplants or seedlings 6-10 feet apart. Elderflowers can spread, so proper spacing ensures adequate air circulation and room for growth.

Fertilization:

Application Tips:

• Follow the directions on the fertilizer package to avoid over-fertilization.

• Apply the fertilizer evenly around the base of the plants and water thoroughly to help the nutrients reach the roots.

Additional Tips:

• Elderflower grows best in well-drained soil rich in organic matter, so consider adding compost to improve soil fertility and structure.

• Mulch around the plants to help retain moisture, suppress weeds, and regulate soil temperature.

• Ensure that elderflower receives consistent moisture, especially during flowering, to prevent stress and promote abundant blooming.
