How to Divide Bougainvillea: Step-by-Step Instructions

Dividing bougainvillea is a great way to propagate new plants and manage the size of your existing shrub. Proper division ensures healthy growth and vigorous new plants. Follow these step-by-step instructions to successfully divide your bougainvillea.

Tools and Timing

  • Sharp pruning shears or a saw
  • Garden gloves
  • Pruning saw or spade
  • Rooting hormone (optional)
  • Watering can

The best time to divide bougainvillea is during its dormant period, typically in early spring or late winter. Ensure the plant has adequate water before starting.

Step 1: Prepare the Plant

Water the bougainvillea thoroughly a day before dividing. This softens the soil and reduces stress on the plant during the process. Wear gloves to protect your skin from thorns.

Step 2: Dig Around the Root Ball

Using a spade or garden fork, carefully dig around the base of the plant, about 12-18 inches from the main stem. Loosen the soil and gently lift the root ball out of the ground.

Step 3: Divide the Root Ball

Place the root ball on a flat surface. Using a sharp saw or pruning shears, cut through the root ball into sections. Each section should have a healthy root system and some stems or branches.

Step 4: Prepare the Divisions

If desired, dip the cut ends into rooting hormone to encourage root development. Trim any damaged roots or stems to promote healthy growth.

Step 5: Plant the Divisions

Plant each division in well-draining soil, at the same depth it was growing before. Water thoroughly to settle the soil around the roots.

Step 6: Care After Division

Keep the newly planted divisions in a shaded area for a few days. Water regularly to keep the soil moist but not waterlogged. Gradually expose them to full sunlight as they establish.

Tips for Success

  • Ensure each division has enough roots to support growth.
  • Avoid dividing during extreme heat or drought conditions.
  • Use clean, sharp tools to prevent disease transmission.
  • Be patient; new growth may take several weeks to appear.

Dividing bougainvillea can be a rewarding process that results in new, vibrant plants. With proper technique and care, your bougainvillea will thrive and beautify your garden for years to come.
