Learn why division is important in plant propagation. Discover how this cost-effective method can help renew and rejuvenate plants, control plant size, and preserve endangered species. Find out the timing and techniques for successful division.


Propagation is an essential aspect of gardening that allows for the expansion and reproduction of plants. One of the most common methods of plant propagation is division, which involves separating a plant into multiple sections, each containing roots and shoots. But why is division important in plant propagation? In this article, we will explore the reasons why division is a valuable technique for gardeners and plant enthusiasts.

Division: A Cost-Effective Method for Plant Reproduction

Division is a popular method of plant propagation for several reasons. Firstly, it is a cost-effective way to increase your plant collection. Instead of purchasing new plants from nurseries, division allows you to create multiple new plants from a single existing one. This not only saves money but also enables you to expand your garden without the need for additional resources.

Renewal and Rejuvenation of Plants

Another important aspect of division in plant propagation is the renewal and rejuvenation it provides for plants. Over time, clumping or creeping herbaceous perennials can become overcrowded, resulting in reduced growth and flowering. By dividing these plants, you can create more space and prevent overcrowding, which can lead to disease and poor growth. Division stimulates fresh growth and improves the overall health and vigor of the plant.

Maintenance of Plant Size and Control

Division is a useful technique for controlling the size of plants. If a plant has grown too large for its designated space, dividing it allows you to create smaller sections that can be replanted in different areas. This effectively reduces the size of the parent plant, prevents it from encroaching on other plants, and helps maintain a harmonious garden layout. Whether you want to maintain the size of a plant or reduce its size, division provides an effective solution for gardeners.

Preservation and Conservation of Plant Species

In addition to its practical benefits for gardeners, division plays a crucial role in the preservation and conservation of plant species. By dividing and propagating plants, rare and endangered species can be preserved and conserved. This is especially important for species that are at risk of extinction due to habitat loss or other factors. Division allows for the creation of new plants that can be shared among botanical gardens, conservation organizations, and passionate individuals, ensuring the continued existence of these valuable plant species.

Easy and Reliable Method of Propagation

One of the reasons division is a preferred method of plant propagation is its simplicity and reliability. Unlike other propagation techniques such as seed starting or cuttings, division requires minimal effort and expertise. It can be done by amateur gardeners and new plant enthusiasts with ease. Division generally has a high success rate, as each divided section already possesses essential vegetative parts for growth. This makes it an accessible and effective method for propagating plants.

Timing and Techniques for Successful Division

To achieve successful division, it is important to consider the timing and techniques specific to each plant. Dividing plants is typically done when they are not actively growing, such as in the early spring or late summer. This is because plants are less vulnerable to stress during these periods, allowing them to recover and establish themselves more effectively. Certain plants, like deciduous plants, should be divided while dormant, while evergreens can be divided once new growth has hardened off.

It is also essential to follow proper techniques when dividing plants. The entire plant should be carefully lifted, and the crown and root ball should be divided into two or more sections using sharp knives or spades, ensuring that each section has healthy roots and shoots. After division, excess soil should be removed, and any dead growth should be pruned. The divided sections can then be replanted in prepared holes and watered adequately to promote establishment.


In conclusion, division is an important technique in plant propagation due to its cost-effectiveness, ability to renew and rejuvenate plants, control plant size, preserve endangered species, and its accessibility for gardeners of all skill levels. By dividing plants, gardeners can increase their plant collection, enhance the health and vigor of existing plants, and contribute to the conservation of rare and endangered species. With proper timing and techniques, successful division can be achieved, allowing for the expansion and reproduction of various plant species. So, the next time you need to propagate your plants, consider using the division method to create new and vibrant additions to your garden.
