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.

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)

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
