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.

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

Tuberous Roots

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”
