What is the most effective recommended strategy for removing O. umbellatum from a landscape?
Answer
Digging out the entire bulb system upon emergence in spring.
To successfully eradicate Star of Bethlehem, which persists via underground bulbs, physical removal of the entire bulb structure is necessary. The most practical and effective time recommended for this intervention is when the plant first emerges in the spring. During this early stage, the plant is easier to locate before its foliage growth becomes dense and overgrown, allowing gardeners to target the underground bulbs accurately. Because the plant reproduces by producing numerous small offsets from these bulbs, the excavation process must be thorough and meticulous to ensure no fragments are left behind to regenerate growth in subsequent seasons.
