Separation & Division
Quick Facts:
 Propagation is accomplished by
the use of underground plant
parts.
 These parts have two functions:
#1 Food Storage
#2 Reproduction
We take advantage of a natural
plant reproduction process.
Bulbs and corms are the
reproductive structures that we
use in separation.
Flower Bud
Foliage Leaves
Bulb Scales
Basal
Plate
BULBLETS
Cormels
• Bulbs form offsets or bulblets.
• Corms form cormels.
These structures can be
separated when the plant dies
back.
 Not a natural process
 Utilize Rhizomes, Tubers,
& Tuberous Roots
 We must mechanically
separate (cut away)
 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”
