Multiply your garden with plant division

As the South African summer bathes our gardens in a tapestry of colours, the desire to expand and enhance our outdoor spaces becomes irresistible. Fortunately, there’s a budget-friendly gardening technique that not only breathes new life into your plants but also multiplies the beauty of your garden – plant division. 

In this comprehensive guide, we’ll explore the art of dividing plants, sharing insights, easy techniques, and the wonders of Wonder products to ensure your garden flourishes. Let’s embark on the journey of budget-friendly garden multiplication.

What is plant division?

Plant division, also known as clump or root division, is a gardening practice where mature plants are split into smaller sections. This process revitalises the plants, stimulates new growth, and allows you to propagate them across different areas of your garden.

How to successfully divide your plants

When is the time to divide?

Timing is crucial for successful plant division, and in summer, the ideal moments are during early mornings or late afternoons. This minimises stress on the plants and provides them with a better environment to recover. Aim to divide your plants every three to four years, ensuring a consistent rejuvenation cycle.

Practical ways to divide your plants

For perennials begin by gently lifting the plant from the ground. Using a sharp knife or spade, divide the root ball into manageable sections, ensuring each segment has healthy roots and shoots. 

With grasses it’s important to employ a sharp shovel to cut through the root ball, aiming for sections with sturdy roots and shoots.

For shrubs make sure to dig around the shrub, exposing its roots, and then divide it into smaller, more manageable sections.

Planting after division

After the division process, the planting phase is equally vital to ensure the continued health and growth of your plants. 

For perennials, replant the divided sections in their desired locations, maintaining proper spacing. Water thoroughly post-planting to alleviate stress on the plants. 

With grasses, reposition the divided sections, making sure they are at the same depth as the original plant. Generous watering is essential to settle the soil around the roots. 

For shrubs, plant each divided section in its new location, ensuring it sits at the same depth as the original shrub. Thorough watering, using fertiliser and introducing a layer of mulch around the base contribute to a smooth transition and encourage root growth.

Expert tips

  1. Watering: Hydrate your plants a day before division to minimise stress and promote easier separation.
  2. Balance: Ensure that each divided section has a good balance of roots and foliage for a successful transition.
  3. Use quality tools: Invest in sharp, high-quality knives or spades to ensure clean cuts, minimising damage to the plant.
  4. Rejuvenate soil: Before replanting, enrich the soil with Wonder Shake ‘n Grow Special Fertiliser. This replenishes nutrients and sets the stage for healthy post-division growth of leaves and flowers.
