When it comes to multiplying lily bulbs, there are two main methods: offsets and division. Let’s take a look at each method in turn.
Offsets are small bulbils that form on the sides of mature lily bulbs. These can be carefully removed and replanted to create new plants. To do this, simply dig up the parent bulb and gently brush away any dirt. Using a sharp knife, carefully cut through the flesh of the bulb until you reach the offset (it should be attached by a small root). Gently twist or pull the offset free, taking care not to damage the parent bulb. Plant the offset in well-draining soil and water well. Keep an eye on it over the coming months – if it starts to produce its own offsets, you can repeat the process to create even more plants!
Division is another way of increasing your lily population. This involves dividing up existing bulbs into smaller sections, each with its own ‘eye’ or growing point. Once again, begin by digging up the parent bulbs and cleaning off any dirt. Using a sharp knife or spade, divide the bulbs into sections ensuring that each section has at least one good ‘eye’. Replant immediately in well-drained soil and water well
