Planting and Care Tips

• Planting Depth: As a general rule, plant bulbs at a depth twice their height. This helps protect the bulb and supports strong stem growth.

• Watering: Water the bulbs thoroughly after planting to settle the soil. Maintain consistent moisture during the growing season, but avoid waterlogging, which can cause bulb rot.

• Mulching: Apply a layer of mulch to help retain soil moisture, regulate temperature, and suppress weeds. Organic mulches like straw or bark chips are ideal.

• Fertilization: Apply a balanced, slow-release fertilizer at planting time to provide essential nutrients for growth and flowering. Follow up with a liquid fertilizer during the growing season to support ongoing development.
