Simple Steps for Dividing Overgrown Perennials


Perennials are plants that come back year after year.  You may have heard that you are supposed to divide perennials without knowing what that means for your particular plant.  I will walk you through dividing your perennials.  It isn’t hard but there are some things you need to know to do it correctly.

Signs A Perennial Needs Dividing

Perennials that need dividing how several symptoms.  The plant may have a bald spot in the center where the oldest part of the crown has died.  Some perennials have progressively smaller blooms and may stop blooming altogether until they are divided.  Some perennials can outgrow their spot in the garden.

How Often To Divide Perennials

Perennials grow by adding plant matter to the crown of the plant.  Aggressive perennials like aster may need to be divided every two to three years.  Less aggressive perennials like a black-eyed susan may need to be divided every 3-4 years.  Plants like hostas may go years before needing to be divided.

Benefits Of Dividing Perennials

Dividing perennials has several benefits.

Reinvigorating the Plant

Perennials that need division may start to decline.  The blooms, as mentioned, may get smaller and smaller or even stop altogether.  Colored bearded iris may start having only white flowers.  A thicket of perennials may start to compete so much for water, nutrients, and sunlight with itself that the plant declines.

Control Growth

Some perennials grow so large that they crowd out other plants in the area.  Mint and plants in the mint family are notorious for this.  Digging the plant up and dividing it can give the other plants a chance to continue growing.

Gives You Extra Plants

Sometimes, you want extra plants.  You may be planting a new area and want some transplants or to share them with neighbors.  You have already paid for the perennial, so dividing it will give you free plants to share.  One caution is that you are not supposed to share perennials that are patented by the developer.

Pick The Day

Perennials should not be blooming when they are divided. They need to put their energy toward root and foliage growth, not blooms.

 Pick an overcast day to divide the plants.  A sunny, hot day can dry out the roots of the perennial before you can transplant the new plants.  Pick a day when rain is forecast for the next few days to water the plant and help it recover from division.

Time Of Year

Fall blooming perennials should be divided in the spring. 

  • The new growth makes it easier to find the plant that needs dividing.
  • Smaller stems and leaves are easier to handle without harming them.
  • The stored-up energy in the root helps the plant recover and start to grow.
  • The plants will have a full growing season to recover before winter dormancy.

Divide spring and summer blooming plants in the fall.

  • It is easy to find the plants.
  • There is less gardening work in the fall.
  • Divide at least four weeks before the first frost to let the roots recover before winter.

Step By Step

  1. Water the area around the plant to be divided the day before you dig up the plant. If you are planning to transplant the new plants in your garden the same day, water that area the day before, too.
  2. Dig up the plant that you plan to divide. Use a spade or garden fork and be careful not to injure the plants as you dig it up.  Make a cut beside the plant on all four sides and then pry the plant up to protect the roots.
  3. Remove the dirt from around the roots.
  4. Divide the plant into several parts based on the type of root system as described below.
  5. Plant the new pieces. If you are not planting the new pieces immediately, wrap the roots in a wet towel and place them in the shade.  Keep them cool and moist until you plant them.

How To Divide

Perennials have several root systems. They need to be divided a little differently depending on the root system.

Spreading Root Systems

Ornamental grasses such as pampas grass and some other plants have a mass of roots that are tangled with one another.  Pull the plant roots apart, making sure each piece has four or five stems and the associated root.  You can also cut them apart.  Discard the center part if there is a hole or dead spot there.

Clumping Root Systems

Plants like daylilies and hostas with a clumping root system should be cut apart with a sharp knife.  Keep several eyes, or buds, with each piece.  If you want more plants, you can cut the pieces so they only have a single eye.  However, the plant will need to grow another season before blooming again.

Rhizomes

Divided Iris

Plants like bearded iris have a rhizome that grows at or just a little above ground level.  Cut each rhizome into sections with a single fan of leaves on them.  Cut the fan of leaves back by half so the smaller rhizomes can support them.  If you find a part of the rhizome has insect damage or cuts, discard that part.  Plant rhizome pieces so the top of the rhizome is just visible above the soil.

After Care

Plant the new pieces as soon as possible so they stay in good shape.  Water the plants after transplanting them.  Do not fertilize the plants the first year so they do not put out more foliage than the roots can keep hydrated and fed.

Do Not Divide

Perennials with long tap roots, such as butterfly weed, do not divide well.  You should put them in a place that is large enough for them to live out their lives at their mature size.

They are young plants that establish quickly in your garden, providing fast ground cover and stunning visual appeal due to their tall ornamental plumes. They require minimal maintenance once established, thrive in well-drained soil, and help reduce soil erosion while supporting local biodiversity, making them an excellent choice for both beauty and ecological health in landscaping. Ideal Planting Conditions For Pampas Grass They flourish best in specific environmental conditions that cater to their natural growth patterns. To truly thrive, they require attention to soil type, sunlight, and watering guidelines-each of which plays an essential role in ensuring robust growth. Soil Requirements The journey begins with selecting the right soil. It prefers well-drained soil with a pH range of 5.5 to 7.0. Heavy clay soils or soggy areas are detrimental and should be avoided, as they can lead to root rot, sending your hard work down the drain. To prepare your garden bed properly, you can enhance its fertility and drainage by incorporating organic matter such as compost. This not only improves the soil but also nourishes the plants, providing a solid foundation for growth. Establishing this healthy base is vital for a thriving garden. Remember, the goal is to make an place where the roots can spread easily without suffocation from excess moisture. If you're uncertain about your soil's acidity, consider using a simple pH test kit available at garden centers. Sunlight Needs Once you've laid out the perfect soil, consider where you'll be placing your plants. These beauties crave full sunlight and need at least 6 hours of direct sun daily to perform their best. A sunny spot encourages healthy foliage and leads to bountiful blooms that transform any landscape into a visual delight. In contrast, shaded areas could result in stunted growth and fewer blossoms. Some gardeners might argue that it can tolerate partial shade; however, their vibrant life shines most brightly under the sun's embrace. While seeing some success in shaded areas isn't impossible, those looking for abundant tall plumes are better off sticking to full sunlight exposure. Watering Guidelines After securing the right soil and sunlight, watering becomes the next focal point in your care routine. During the first growing season, it's important to water regularly to help establish a deep and extensive root system-think of it as giving your plant the hydration it needs while it gets settled in its new home. Aim for approximately 1 inch of water per week, ensuring that the soil remains moist but not waterlogged; sogginess can weaken roots. Once established, rest assured knowing that it demonstrates drought tolerance, requiring less frequent watering going forward. This resilience means you can enjoy their striking presence with minimal maintenance once they've rooted themselves well.

As we shift focus now to how best to care for these impressive plants, the right maintenance techniques will ensure they flourish robustly over time. Maintenance Tips for Lush Growth Keeping it healthy requires minimal yet consistent care. A crucial part of maintaining its integrity is trimming back the foliage in late winter. This practice not only encourages fresh new growth in spring but also helps reshape the plant, giving it a tidy appearance as the growing season begins. However, it's important to avoid cutting too close to the ground; doing so can damage the base of the plant and hinder its ability to flourish. Fertilization To ensure your it grows robustly, it's advisable to use a balanced, slow-release fertilizer at the onset of spring. A fertilizer with an N-P-K ratio of 10-10-10 will provide just the right nutrients to support lush growth without overwhelming the plant. You simply sprinkle the fertilizer around the base, following package instructions for quantity, and water lightly afterward to activate the nutrients. This step not only enhances appearance but helps develop strong roots that stabilize the plants against wind or heavy rain. Winter Care In regions where winter temperatures dip significantly, providing extra protection for your plants is essential. One of the simplest ways to safeguard them against freezing temperatures is by applying a layer of mulch around their base. Opt for organic materials like straw or shredded leaves-these not only act as insulation but also decompose over time, enriching your soil in the process. For those living in warmer climates, this step may be less critical; however, if there's an occasional frost warning, adding mulch could mean the difference between surviving and thriving come spring. With these essential aspects of care in mind-regular trimming, appropriate fertilizing, monitoring for pests, and preparing for winter-you'll be well-equipped to foster healthy growth and stunning beauty in your landscape as seasons change. Creative Decorative Uses One wonderful aspect of it is its plumes, which can be dried for use in various indoor arrangements. This not only adds a touch of nature to your home but also offers a rustic, cozy feeling that's perfect for any decor style.

The key is to choose tall vases that showcase the height of the stalks, creating visual interest and drawing the eye upward. Add some twinkling fairy lights around these arrangements for an extra touch of magic during evening gatherings. Dried stalks lend beauty to arrangements and are long-lasting, making it a terrific choice for individuals who appreciate decor that requires minimal upkeep.

Its elegant yet natural look serves as a stunning backdrop for ceremonies and receptions. Envision an archway adorned with its lush, or long-stemmed plumes placed delicately across tables as centerpieces - both add a breathtakingly stylish yet grounded element to your celebration. Moreover, you can get creative with aisle decorations to guide guests through a sea of soft, billowing grass-transforming an ordinary corridor into an enchanting pathway.

By incorporating it into this aesthetic, you can achieve a warm and inviting atmosphere. The fluffy plumes contrast beautifully with woven baskets and other natural elements.

hosta plant - TN Nursery

Hosta

Hosta - Plantain Lilies Hostas are shade-loving perennials known for their large, heart-shaped, and often variegated leaves and spikes of bell-shaped flowers, making them popular choices for garden borders and landscaping in low-light areas. They are renowned for their lush foliage and graceful appearance, which offer many benefits when incorporated into landscaping designs. These versatile perennials have gained popularity for their ability to enhance outdoor spaces with their aesthetic appeal, adaptability, and ease of maintenance. It is an attractive herbaceous plant that can grow up to 4 feet in height, although a height of 18 inches is more common. There are several species of them, each with slight differences in leaf color. Each species has a different bloom, making exceptional focal points in any garden. Hosta Has Stunning Leaves The type seen most commonly in the United States is the "Keepsake." The charming green leaves ringed with yellow accents are popular because of their hardiness in different climates and the beautiful vistas they create in a garden. Sometimes, the lighter color rings are shades of white rather than yellow, but they don't lose any eye-catching effects. They have leaves of a single color, usually dark green. All their leaves are sturdy and ribbed, even if they're longer and tapered rather than cheerfully oval. Compliment Your Landscape With Hostas Most versions have pretty purple or white flowers that bloom in the early summer through the beginning of fall. The flower buds form in the middle of spring and are generally the same color as the flowers. Even when they're just budding, they are beautiful plants that complement everything else in the garden. Once the buds bloom, the flowers form trumpet, bell, or elongated pendulous shapes. Only one version of these flowers has a strong scent, called the "August Lily." It's a shy flower, blooming in the evening and closing up again by morning, so it'll brighten up any garden when the sun goes down. It Does Great With Other Plants When they are surrounded by flowers of similar colors, such as California bluebells for the species with violet flowers or tuberose for the white-flowered species, it creates a breathtaking effect. Alternating the various species in concentric rings would increase their appeal and let them truly shine. The blooms, such as bees, butterflies, and hummingbirds, are essential for pollinators. The flowers provide nectar, and the leaves collect dew in the mornings, allowing these little creatures to drink while visiting the garden. These plants grow in partial shade or full shade, hence suitable for gardens that may offer limited sunlight. They grow well in well-draining and nutrient-filled soils and should be watered consistently, especially during dry periods.  They are perennials and go dormant in winter. Prune dead foliage in the fall and then put a layer of mulch to protect the roots from freezing.  They come in all sorts of sizes, from small miniatures to large sprawling plants. Their foliage comprises beautiful green, blue and gold that may have different patterns.  Snails or slugs are common enemies for the plants. You can use eggshells or diatomaceous earth around the base. You can also reduce pest problems by maintaining a clean environment and ensuring good air circulation in the garden.   Hostas are perfect for container gardening and, therefore, can be placed on the patio or in other small spaces. It is advisable to plant the flower in a pot with a good drainage hole; water it frequently and place it in a shaded area.
