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

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

5. Bulbs
Flower Bud
Foliage Leaves
Bulb Scales
Basal
Plate
BULBLETS

6. Corm
Cormels

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

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

12. 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”
