Whether you're transplanting Oriental lily bulbs to make room expand your planting or to share bulbs with garden friends the easiest way to do this is to remove the bulbs that grow long the stem just below the soil line. The new bulbs produced are smaller than the original lily bulb and cluster along the stem near the surface of your garden soil as illustrated by the picture of Oriental lily bulbs above. These bulbs can be easily collected by excavating a few inches of soil with a garden trowel and planted in a new location. The best time to harvest these baby bulbs is in the fall after they develop the beginnings of their own root systems that can support them. Transplant these bulbs into a new location in the garden, or a large pot, where the soil is loose and fast-draining.
