The Wonderful World of Horticulture: Exploring Propagation Techniques

Learning Objective

At the end of the lesson, you will be able to understand different propagation techniques used in horticulture and their significance.

What do you already know about horticulture and plant propagation?

Introduction to Horticulture

Horticulture is the science and art of cultivating plants. It has been practiced for thousands of years.

Importance of Plant Propagation

Plant propagation is the process of creating new plants from existing ones. It helps in preserving specific plant traits and increasing plant populations.

Vegetative Propagation

Vegetative propagation involves growing new plants from vegetative parts like stems, leaves, or roots. Examples include cuttings, grafting, and division.

Sexual Reproduction

Sexual reproduction involves the union of male and female reproductive cells (pollen and egg) to produce offspring with genetic variation.

Propagation Techniques: Cuttings

Cuttings involve taking a piece of a plant and encouraging it to develop roots and grow into a new plant. It's commonly used for herbaceous plants.

Propagation Techniques: Grafting

Grafting involves joining two different plant parts to create a new plant with desirable traits. It's commonly used for fruit trees and roses.

Propagation Techniques: Division

Division involves separating a clump of plants into smaller sections, each capable of growing into a new plant. It's commonly used for perennials.

Write down 3 things you learned in this lesson.

Have students enter three things they learned in this lesson. With this they can indicate their own learning efficiency of this lesson.

Write down 2 things you want to know more about.

Here, students enter two things they would like to know more about. This not only increases involvement, but also gives them more ownership.

Ask 1 question about something you haven't quite understood yet.

The students indicate here (in question form) with which part of the material they still have difficulty. For the teacher, this not only provides insight into the extent to which the students understand/master the material, but also a good starting point for the next lesson.
