Cuttage

• Types of cuttings
• Herbaceous
• Softwood
• Hardwood
• Length 3 - 5 for herbaceous, 6-8 for
  softwood/hardwood. Generally, the longer a
  cutting, the better
• Need a MINIMUM of 2 nodes

6
Sticking easy-to-root cuttings directly in the
ground
7
Cuttage

• Factors affecting rooting
• Age of stock plant
• Nutrients in stock plant
• Flowers buds present/absent
• Temperature (top of cutting vs. bottom)
• Wounding
• Application of auxins
• Moisture/aeration of medium

Cuttage

• Factors
• Time of year
• Woody plants
• Deciduous best in fall/winter when dormant
• Narrow-leaved evergreens - best in fall/winter
• Broadleaved evergreens - best in summer
• Herbaceous
• take during spring with new growth

Cuttage

• Types of cuttings
• Tip cutting
• Leaf-bud cutting

Layerage

• Process of forming roots on a stem that is still
  attached to a plant
• Benefits Renew an existing plant. Direct
  energy from mother plant
• Problems results in limited numbers of plants.
  Disease transmitted to new plant

29
Layerage

• Types
• Tip-layering. Often done with raspberries and
  other brambles). Tip of shoot inserted into
  ground upside down
• Simple layering. Done in spring. 6 of tip is
  exposed. Wired and staked. Used on narrow-leaved
  evergreens

Layerage

• Types
• Mound layering (stooling). Used on low-branching
  shrubs
• Air layering. To rejuvenate a leggy woody
  shrub or houseplant.
• Girdle stem (cut phloem and cambium)
• Wrap in moist sphagnum moss
• Wrap in plastic and aluminum foil
