Vegetative propagation in mint occurs by suckers.

Suckers are adventitious shoots that arise from the roots of a plant. In the case of mint, these suckers arise from the roots and grow into new plants. This type of vegetative propagation is advantageous for mint growers because it allows them to quickly and easily propagate new plants without having to rely on seeds.

Here are some key points about the process of vegetative propagation by suckers in mint:

- Mint plants can produce many suckers, which can lead to dense mats of plants that can be difficult to control.
- Suckers can be removed and transplanted to start new plants, or they can be left in place to grow into new plants.
- Suckers can be encouraged to form by cutting back the stems of the mint plant, which stimulates the growth of new shoots from the roots.
- Vegetative propagation by suckers can result in plants that are genetically identical to the parent plant, which can be advantageous if the parent plant has desirable characteristics such as strong flavor or resistance to disease.
- However, vegetative propagation can also result in a lack of genetic diversity, which can make the plants more vulnerable to diseases and pests.

In summary, vegetative propagation by suckers is an important method of propagating mint plants, allowing growers to quickly and easily produce new plants with desirable characteristics. However, it is important to carefully manage the growth of these plants to prevent them from becoming too dense and to maintain genetic diversity in the population.

Sucker is a mode of vegetative propagation. It is a non-green slender stem branch which arises from the underground base of erect shoot or crown. It grows horizontally in the soil and ultimately comes out to form a new aerial shoot or crown. Each sucker has nodes with scale leaf and axillary bud. For example, mint has the sucker. It has adventitious root and scale leaf.
