Perennial plants are a staple in many gardens, offering a wide range of benefits including vibrant flowers, lush foliage, and a low-maintenance gardening experience. However, to keep these plants healthy and thriving, it’s essential to perform regular maintenance tasks, including dividing. Dividing perennials is a process that involves separating the roots of a plant to create new, smaller plants, and it’s crucial for maintaining plant health and promoting new growth. In this article, we’ll explore what happens if you don’t divide perennials and why this process is vital for a successful and beautiful garden.
Why Divide Perennials?
Dividing perennials is an important part of garden maintenance, and it offers several benefits for plant health and garden appearance. When perennials are not divided, they can become overgrown, leading to a range of problems including reduced flowering, decreased plant vigor, and increased susceptibility to disease. By dividing perennials, you can:
Improve Plant Health
Dividing perennials helps to improve plant health by reducing congestion and promoting healthy root growth. When plants become overcrowded, they compete for resources such as water, nutrients, and light, leading to reduced plant vigor and increased susceptibility to disease. By dividing the roots, you can reduce congestion, promote healthy root growth, and improve overall plant health.
Enhance Garden Appearance
Dividing perennials also enhances garden appearance by promoting new growth and increasing flower production. When plants become overgrown, they can become leggy and produce fewer flowers, leading to a dull and uninteresting garden. By dividing perennials, you can promote new growth, increase flower production, and add vibrancy and color to your garden.
What Happens if You Don’t Divide Perennials?
So, what happens if you don’t divide perennials? If you don’t divide your perennials, you can expect a range of negative consequences, including:
Reduced Flowering
One of the most noticeable consequences of not dividing perennials is reduced flowering. When plants become overgrown, they often produce fewer flowers, leading to a dull and uninteresting garden. This is because the plant’s energy is focused on maintaining its existing growth, rather than producing new flowers.
Decreased Plant Vigor
Not dividing perennials can also lead to decreased plant vigor, as the plant’s energy is spent trying to maintain its existing growth. This can result in weak and spindly stems, reduced leaf growth, and a general decline in plant health.
Increased Susceptibility to Disease
Overgrown perennials are also more susceptible to disease, as the congested growth provides an ideal environment for pathogens to thrive. By not dividing perennials, you can create a haven for disease, which can quickly spread to other plants in the garden.
Reduced Plant Longevity
Finally, not dividing perennials can reduce plant longevity, as the plant’s energy is spent trying to maintain its existing growth. This can result in a shorter lifespan for the plant, as it becomes increasingly stressed and vulnerable to disease.
When to Divide Perennials
So, when should you divide perennials? The best time to divide perennials depends on the type of plant, but most perennials can be divided in the spring or fall. Dividing in the spring allows the plant to establish itself before the heat of summer, while dividing in the fall allows the plant to establish itself before the cold of winter.
Spring Dividing
Spring is a great time to divide perennials, as the weather is typically mild and there is ample moisture in the soil. This makes it an ideal time to divide plants such as daylilies, hostas, and coneflowers.
Fall Dividing
Fall is also a great time to divide perennials, as the weather is typically cool and there is ample moisture in the soil. This makes it an ideal time to divide plants such as astilbe, bleeding heart, and catmint.
How to Divide Perennials
Dividing perennials is a relatively simple process, but it does require some care and attention to detail. Here are the basic steps:
Prepare the Plant
Before dividing the plant, make sure to water it well the day before. This will help to loosen the soil and make it easier to divide the roots.
Divide the Roots
To divide the roots, gently dig around the plant, making sure to get as much of the root system as possible. Then, use a garden fork or knife to carefully separate the roots, making sure each section has at least one growing eye.
Replant the Divisions
Once you have divided the roots, replant the divisions in a new location, making sure to water well and provide adequate care.

What happens if I don’t divide my perennials?
Not dividing perennials can lead to a decline in their overall health and performance. As perennials grow and mature, they often outgrow their allocated space, leading to overcrowding and increased competition for resources such as water, nutrients, and sunlight. This can cause the plants to become leggy, weak, and more susceptible to disease and pests. Furthermore, the center of the plant may die out, leaving a bare spot and reducing the plant’s overall vigor.
If perennials are not divided, they may also produce fewer flowers or blooms, which can be disappointing for gardeners who value their plants’ aesthetic appeal. In addition, undivided perennials may become more difficult to manage, with overgrown roots and stems that can be challenging to prune or maintain. By dividing perennials regularly, gardeners can help maintain their plants’ health, promote healthy growth, and encourage more abundant flowering. Regular division also provides an opportunity to inspect the roots and stems of the plant, allowing for the removal of any dead or diseased tissue and the redistribution of healthy sections to other areas of the garden.
How often should I divide my perennials?
The frequency at which perennials should be divided depends on the type of plant, its growth rate, and its overall health. Some perennials, such as daylilies and hostas, may need to be divided every 3-4 years, while others, such as peonies and irises, may only require division every 10-15 years. Gardeners should monitor their plants’ growth and watch for signs that division is necessary, such as a decrease in flowering, overcrowding, or a decline in overall health. It’s also important to research the specific needs of each perennial variety, as some may have unique requirements or recommendations for division.
In general, spring and fall are the best times to divide perennials, as the weather is typically cooler and moisture levels are more consistent. Dividing perennials during these periods can help minimize stress on the plants and reduce the risk of transplant shock. It’s also important to handle the roots and stems with care during the division process, making clean cuts and minimizing damage to the plant tissue. By dividing perennials at the right time and with proper care, gardeners can help promote healthy growth and encourage their plants to thrive.
What are the benefits of dividing perennials?
Dividing perennials offers numerous benefits for gardeners, including the opportunity to propagate new plants, improve the overall health and vigor of existing plants, and increase the number of blooms and flowers. By dividing perennials, gardeners can also control the size and shape of their plants, preventing them from becoming too large or unruly. Additionally, division allows gardeners to inspect the roots and stems of the plant, removing any dead or diseased tissue and redistributing healthy sections to other areas of the garden. This can help prevent the spread of disease and promote a more balanced and thriving garden ecosystem.
The benefits of dividing perennials also extend to the overall aesthetics of the garden. By regularly dividing and re-planting perennials, gardeners can create a more dynamic and varied landscape, with a mix of mature and newly planted specimens. This can add visual interest and texture to the garden, as well as provide a sense of continuity and evolution over time. Furthermore, dividing perennials can be a cost-effective way to obtain new plants, as gardeners can share or trade divisions with friends and fellow gardening enthusiasts, rather than purchasing new specimens from a nursery or garden center.
Can all perennials be divided?
Not all perennials can be divided, and some may be more challenging to divide than others. Plants with deep taproots, such as baptisia and coneflower, may be difficult to divide, as their roots can be hard to separate and may be damaged during the process. Other plants, such as peonies and irises, have specific division requirements and may need to be handled with extra care. It’s also important to note that some perennials, such as those with woody stems or a sprawling habit, may not be suitable for division and may be better propagated through other means, such as cuttings or layering.
Before attempting to divide a perennial, gardeners should research the specific needs and requirements of the plant, as well as any potential challenges or limitations. It’s also important to consider the plant’s growth habits and mature size, as well as its overall health and vigor. By understanding the unique needs and requirements of each perennial variety, gardeners can make informed decisions about division and ensure the best possible outcomes for their plants. With proper care and attention, many perennials can be successfully divided and will thrive in their new locations.
How do I divide perennials?
Dividing perennials involves several steps, including preparing the plant, digging and lifting the roots, separating the roots and stems, and re-planting the new divisions. Before dividing, gardeners should water the plant thoroughly and allow the soil to drain, making it easier to handle the roots. Next, the plant should be carefully dug up, taking care to minimize damage to the roots and stems. The roots and stems can then be separated, either by gently teasing them apart or by using a sharp tool to make clean cuts.
Once the roots and stems have been separated, the new divisions can be re-planted in a well-prepared soil mix, with adequate moisture and nutrients. It’s essential to handle the roots and stems with care during the division process, making clean cuts and minimizing damage to the plant tissue. Gardeners should also ensure that the new divisions are planted at the same depth as the original plant and that the soil is firmly firmed around the roots to prevent settling. With proper care and attention, newly divided perennials will establish themselves quickly and thrive in their new locations.
What are the most common mistakes to avoid when dividing perennials?
One of the most common mistakes to avoid when dividing perennials is dividing them at the wrong time. Dividing perennials during periods of extreme weather, such as intense heat or cold, can cause unnecessary stress and reduce the plant’s chances of survival. Another mistake is handling the roots and stems roughly, which can damage the plant tissue and lead to infection or disease. Gardeners should also avoid over-handling the roots, as this can cause them to become waterlogged and prone to rot.
Other mistakes to avoid when dividing perennials include dividing plants that are too young or too old, failing to provide adequate moisture and nutrients, and not providing sufficient space for the new divisions to grow. Gardeners should also avoid dividing perennials that are struggling with pests or disease, as this can spread the problem to other areas of the garden. By avoiding these common mistakes and taking a thoughtful and careful approach to dividing perennials, gardeners can help ensure the best possible outcomes for their plants and enjoy a thriving and vibrant garden.
Can I divide perennials in the summer?
While it’s technically possible to divide perennials in the summer, it’s not always the best time to do so. Summer division can be challenging, as the heat and dryness of the season can cause stress to the plants and reduce their chances of survival. Additionally, many perennials are in active growth during the summer, and division can disrupt this process and cause the plant to become leggy or weak. However, some perennials, such as daylilies and hostas, may be dividing during the summer months, as long as they are provided with adequate moisture and care.
If gardeners do need to divide perennials in the summer, they should take extra precautions to minimize stress and ensure the plants’ survival. This may include providing extra moisture, shade, and nutrients, as well as handling the roots and stems with extra care. It’s also essential to choose a cooler, cloudier day for division, and to avoid dividing plants during periods of intense heat or drought. By taking a careful and thoughtful approach to summer division, gardeners can help their perennials thrive and enjoy a successful and rewarding gardening experience.
