Expanding your garden doesn’t have to mean spending a fortune on new plants. One of the most cost-effective and rewarding ways to increase the size and variety of your garden is by dividing perennials. This technique not only rejuvenates your existing plants but also allows you to create new garden beds without spending a penny. This comprehensive guide will walk you through the process of dividing perennials, offering tips and insights to help you successfully expand your garden.
Understanding Perennial Division
Perennials are plants that live for more than two years and typically flower every year. They often benefit from division, a process where mature plants are separated into smaller sections. Dividing perennials helps manage plant size, improves flowering, and refreshes the plant’s health. Additionally, it provides an opportunity to increase the number of plants in your garden.
Why Divide Perennials?
- Improves Plant Health: Over time, perennials can become crowded and root-bound, which may lead to reduced flowering and overall plant health. Division helps rejuvenate the plant by giving it more space to grow.
- Increases Blooms: Dividing perennials can lead to more vigorous plants and increased flowering.
- Expands Your Garden: By dividing established plants, you can create new garden beds or fill in empty spaces without purchasing additional plants.
When to Divide Perennials
The timing of dividing perennials is crucial to their success. The best time to divide perennials varies depending on the plant type and local climate. Generally, the best times are:
Spring: Early spring, just as new growth begins, is ideal for many perennials. This timing allows plants to establish their roots before the heat of summer.
Fall: Late summer to early fall is another good time, especially for plants that go dormant in winter. This timing gives plants a head start on establishing roots before the winter freeze.
Signs Your Perennials Need Dividing:
- Reduced Blooming: If plants are no longer producing as many flowers as they once did.
- Crowded Growth: When plants begin to crowd each other and outgrow their space.
- Center Die-Out: If the center of the plant dies or looks sparse while the outer edges are lush.
Preparing for Division
Before you start dividing your perennials, proper preparation is key. This ensures the health of the plants and the success of the new divisions.
1. Choose the Right Tools:
- Garden Fork or Spade: Use a garden fork or spade to gently lift the plant from the soil.
- Sharp Knife or Pruners: A sharp knife or garden pruners will help you divide the plant into sections.
2. Prepare the Soil:
- Soil Quality: Ensure the soil is well-draining and rich in organic matter. Amend the soil with compost or well-rotted manure if necessary.
- Digging Space: Clear the area where you plan to replant the divided sections, ensuring ample space for new growth.
How to Divide Perennials
Follow these steps to successfully divide your perennials:
1. Choose and Prepare the Plant:
- Select Mature Plants: Choose healthy, mature perennials that have been in the ground for at least a few years.
- Water the Plant: Water the plant thoroughly a day or two before dividing to make it easier to lift.
2. Dig Up the Plant:
- Loosen the Soil: Use a garden fork to gently loosen the soil around the plant. Be careful not to damage the roots.
- Lift the Plant: Carefully lift the entire plant from the ground, keeping as many roots intact as possible.
3. Separate the Roots:
- Inspect the Roots: Examine the root system to determine where to make the divisions. Look for natural breaks or sections.
- Divide the Plant: Use a sharp knife or garden pruners to divide the plant into smaller sections, ensuring each section has roots and shoots. For large plants, you may need to use a saw or pruning shears.
4. Replant the Divisions:
- Prepare Planting Holes: Dig planting holes in the prepared soil, spacing them according to the plant’s requirements.
- Plant at the Same Depth: Replant the divisions at the same depth they were growing previously. Firm the soil around the roots to eliminate air pockets.
- Water Thoroughly: Water the newly planted sections thoroughly to help them establish roots and settle into their new location.
5. Care for Newly Divided Plants:
- Mulch: Apply a layer of mulch around the newly planted divisions to retain moisture and regulate soil temperature.
- Monitor Watering: Keep the soil consistently moist but not waterlogged. Regular watering is crucial for newly divided plants as they establish their root systems.
- Fertilize: Apply a balanced fertilizer to support new growth and root development.
Tips for Successful Perennial Division
1. Choose the Right Perennials: Some perennials are more amenable to division than others. Hardy perennials like hostas, daylilies, and astilbes are excellent candidates for division.
2. Divide in Groups: For larger plants, consider dividing them into several smaller sections to create multiple new plants. This approach maximizes the benefits and increases the number of plants you can add to your garden.
3. Avoid Over-Division: While it’s tempting to divide plants into many sections, avoid over-dividing as this can stress the plant and reduce its vigor. Ensure each section is substantial enough to grow well.
4. Follow Up with Care: After planting, monitor the health of your newly divided perennials. Watch for signs of stress or disease and address any issues promptly.
