Separation & Division Quick Facts: Propagation is accomplished by the use of underground plant parts. These parts have two functions: #1 Food Storage #2 Reproduction

Separation We take advantage of a natural plant reproduction process. Bulbs and corms are the reproductive structures that we use in separation.

Bulbs Flower Bud Foliage Leaves Bulb Scales Basal Plate BULBLETS

Corm Cormels

Propagation: Bulbs form offsets or bulblets. Corms form cormels. These structures can be separated when the plant dies back.

Utilize Rhizomes, Tubers, & Tuberous Roots Division Not a natural process Utilize Rhizomes, Tubers, & Tuberous Roots We must mechanically separate (cut away)

When plants are crowded, they may be divided Propagation: When plants are crowded, they may be divided They are removed from the soil by digging They are then cut--remember to leave an “eye”
