INTRODUCTION
• A plantlet is a tiny version of a plant still
attached somewhere to its parent plant
• The plantlets obtain food from the parent
plant until they are established

OBTAINING PLANTLETS
• Plantlets can be obtained by different methods:
1. production of plantlets from runners
2. production of leaf plantlets
3. production of plantlets from offsets

2. PRODUCTION OF LEAF
PLANTLETS
• Some types of plant develop plantlets on the
edges of mature leaves
• These can be detached from the leaf and
grown in small pots of compost
• An example of this is the Mexican Hat plant

3. PRODUCTION OF
PLANTLETS FROM OFFSETS
• An offset is a tiny plantlet that develops as a sideshoot at the base of the parent plant
• Sometimes different offsets are produced andthese then form a clump at the base of the parent
plant
• An example of this is the Mother-in-law’s Tongue plant

METHODS OF PROPAGATING
OFFSETS
• A plant with offsets can be propagated bydivision
• This means separating the offsets from the parent, normally using a sharp knife
• The offsets can then be planted in newlocations

Advantages of Vegetative
Propagation
• Exact copies of parent plants can be produced inmost cases
• Often simple and relatively quick
• Large plants can sometimes be produced in a short period of time
• Good quality and uniformity among plants produced

Disadvantages of Vegetative
Propagation
• All offspring share common susceptibility
to disease
• Not suitable if variation is desired
