How to Split Plants: A StepbyStep Guide
How to Split Plants?
To split plants, begin by digging up the parent plant and removing loose dirt around the roots.
Separate the plant into smaller divisions by pulling apart, cutting, or using forks.
Each division should have three to five shoots and healthy roots.
Keep the divisions shaded and moist until replanted.
Spring is a good time to divide and move perennials, but for plants with fleshy roots, dividing in the fall is better.
Dividing should be done when the plant is not flowering to focus energy on root and leaf regeneration.
It’s important to time the division for four to six weeks before the ground freezes to help roots establish.

Did You Know?
1. Did you know that splitting plants, also known as plant propagation, dates back to ancient Egypt? It was a common practice among Egyptian gardeners, who split plants to increase their inventory and improve their gardens.
2. Splitting plants is not only a method for multiplying your greenery; it can also rejuvenate older plants. By splitting them, you’re essentially prompting the plant to produce new, healthier growth and extend its lifespan.
3. Some plants, such as the spider plant (Chlorophytum comosum), are highly suitable for splitting due to their ability to produce plantlets, or miniature versions of themselves on runners. These plantlets can be easily detached and replanted, resulting in brand new plants!
4. When splitting plants, it’s essential to select a healthy, mature specimen with a strong root system. This ensures that both the parent and the newly split plants have the best chance of thriving independently.
5. Splitting plants is not limited to above-ground growth; it can also be done with certain types of root structures. For example, rhizomes, such as those found in bamboo and iris plants, can be carefully divided to produce new plants.
Benefits Of Dividing Perennials
Dividing perennials is an essential practice for gardeners looking to improve the health and performance of their plants. By dividing a single perennial into multiple sections, you can create more space for the roots to grow and absorb nutrients and water. This increased root space allows the plant to thrive and produce more vibrant foliage and blooms.
Another benefit of dividing perennials is that it helps manage the size of the plant. Over time, perennials can become overcrowded, leading to reduced overall performance. By dividing the plant, you can control its size and prevent it from becoming too large and unruly in your garden.
In addition to managing the size of the plant, dividing perennials also offers the advantage of creating more plants of the same kind for your garden. This is especially beneficial if you have a particular perennial that you love and want to have more of in your garden. Dividing allows you to propagate and multiply your favorite perennials without having to purchase new plants.
Signs It’s Time To Divide
Knowing when to divide your perennials is crucial for their overall health and vitality. One of the signs that it’s time to divide a perennial is reduced plant performance. If you notice that your plant is producing smaller flowers, fewer blooms, or has stunted growth, it may be an indication that it is becoming overcrowded and needs to be divided.
Overcrowded plants compete for nutrients and water, which can result in weaker growth and overall poor performance. Additionally, restricted airflow around overcrowded plants can lead to increased susceptibility to diseases and pests.
By dividing your perennials, you can alleviate these issues and create a healthier growing environment for your plants.
‒ Proper spacing allows for better nutrient and water absorption
‒ Dividing plants promotes air circulation and reduces the risk of diseases and pests
‒ Improved plant performance and increased flower production
Timing And Conditions For Division
Choosing the right time and conditions for dividing your perennials is essential to ensure their successful transplantation and growth. Spring is generally considered the best time to divide and move perennials.
During spring, the soil is usually moist and the weather is mild, providing optimal conditions for the plants to establish their roots.
If you live in an area with dry soil, it is advisable to water the soil a day in advance of dividing the perennials. This ensures that the roots have enough moisture to withstand the division process.
Additionally, dividing on a cloudy or overcast day can help prevent the divisions from drying out too quickly.
If there are showers in the forecast, it’s advantageous to divide your perennials at that time. The rain will provide natural moisture for the new transplants, aiding in their establishment and growth.
- Choose spring for dividing and moving perennials
- Water the soil before dividing if it’s dry
- Divide on a cloudy day to prevent drying out
- Take advantage of forecasted showers for natural moisture
Remember to consider the right time and conditions for dividing your perennials to ensure their successful transplantation and growth.
Techniques For Dividing Perennials
When it comes to dividing perennials, there are several techniques you can use, depending on the specific plant and its root structure. The most common methods include pulling apart, cutting, or using forks to separate the plant into smaller divisions.
Before dividing, dig up the parent plant and remove any loose dirt around the roots. This will make it easier to see the root structure and determine where to make the divisions. Each division should have three to five shoots and healthy roots to ensure its viability.
It’s important to note that different perennials may have specific recommendations for division. For example, hostas are best divided in the spring before they become too large. On the other hand, fall-blooming perennials should be divided in the spring when new growth is emerging. Plants with fleshy roots, such as irises, are generally better divided in the fall when they are dormant.
Care Of Divisions After Separation
After dividing your perennials, it is crucial to provide proper care for the divisions to ensure their successful transplantation and growth.
Here are some tips to follow:
-
Keep the divisions shaded and moist until they are replanted. This will help prevent them from drying out and give them time to acclimate to their new environment.
-
When replanting the divisions, make sure to give them adequate spacing to allow for future growth.
-
Water the newly planted divisions thoroughly and regularly to promote root development.
-
Mulching around the base of the plants can help conserve moisture and suppress weed growth.
It’s important to note that dividing perennials should be done when the plant is not flowering. This allows the plant to focus its energy on root and leaf regeneration instead of flower production.

For successful transplantation and growth of divided perennials, follow these steps:
-
Keep divisions shaded and moist until replanting.
-
Provide adequate spacing for future growth.
-
Thoroughly water the newly planted divisions to promote root development.

Frequently Asked Questions
How do you separate overgrown plants?
To separate overgrown plants, the process begins with creating a circular trench around the plant, approximately 12 inches from its center. Once the trench is in place, the next step is to cautiously use a shovel to lift the root ball out of the soil and onto a tarp for easier maneuvering. Carefully, with both hands, the root ball should be pulled apart into multiple sections, ensuring that each division consists of roots and foliage for proper growth and development.
How do you separate plant stems?
To separate plant stems, gently lay the plant on its side and untangle the root ball using your fingers or hands, gradually dividing the plant into smaller sections. This process ensures that each stem receives enough space and nutrients for healthy growth. After separation, it is crucial to place the plants in an area with bright indirect light, allowing them to thrive and continue their growth journey.
What is the best tool to divide plants?
One effective tool for dividing plants is a garden fork or spade, especially when dealing with larger plants. These tools allow for the easy lifting of the entire root ball, which can then be pried apart into multiple sections. In cases where the growth is densely packed, a sharp spade, hand saw, or the versatile Hori Hori Knife can be used to cut the root ball into manageable pieces.
Can any plant be split?
Yes, many plants can be split in order to propagate or rejuvenate them. Smaller plants like Heuchera, Hosta, and Epimedium can be easily separated by gently lifting and pulling apart the fibrous roots, resulting in smaller clumps that can be replanted. Conversely, larger fibrous-rooted perennials like Hemerocallis (daylily) require a slightly different approach. To divide them, two garden forks need to be inserted into the crown back-to-back, allowing for the separation of the plant into multiple sections for transplanting or rejuvenation.
