Measure the depth using a ruler or simply judge it by placing the bulb in the hole. Plant the bulb with the pointed side up and the basal plate (where the roots emerge) downwards. 4. Spacing: Leave around 4 to 6 inches of space between each bulb to allow for proper air circulation and growth. You can plant several bulbs together to create a cluster or scatter them around the garden. 5. Watering: After planting, water the bulbs thoroughly. This will help settle the soil and encourage root development. However, avoid overwatering as it can cause bulb rot.
