Bougainvillea is a vibrant and hardy plant known for its stunning, colorful bracts. Propagating bougainvillea from cuttings is a cost-effective way to expand your garden, and using natural growth enhancers like bananas and onions can boost the success rate of your cuttings. This guide will show you how to grow bougainvillea from cuttings using these household ingredients.

Materials You Will Need

  • Healthy bougainvillea plant
  • Ripe banana
  • Onion
  • Sharp knife or pruning shears
  • Small container or bowl
  • Clear plastic bag
  • Pot with well-draining soil

Step-by-Step Guide to Growing Bougainvillea from Cuttings

Step 1: Prepare the Bougainvillea Cuttings

  1. Select Healthy Stems: Choose healthy, semi-hardwood stems from an existing bougainvillea plant. The best cuttings are those that are not too young or too old, typically from the current or previous season’s growth.
  2. Cut the Stems: Using sharp pruning shears or a knife, cut 6-8 inch long sections from the selected stems. Each cutting should have at least 4-6 nodes (the points where leaves attach to the stem).
  3. Remove Leaves: Strip the lower leaves from the cuttings, leaving a few leaves at the top. This helps the cutting focus on root development rather than maintaining foliage.

Step 2: Prepare the Natural Growth Enhancers

  1. Banana Paste: Peel a ripe banana and mash it into a smooth paste. Bananas are rich in potassium and other nutrients that can stimulate root growth.
  2. Onion Juice: Finely chop an onion and extract the juice by pressing it through a sieve or cheesecloth. Onion juice contains natural rooting hormones that can enhance root development.

Step 3: Treat the Cuttings

  1. Dip in Onion Juice: Dip the base of each bougainvillea cutting into the onion juice, ensuring that the cut ends are well-coated.
  2. Apply Banana Paste: After dipping in onion juice, coat the base of the cuttings with the mashed banana paste. This will provide a nutrient-rich environment for the cuttings.

Step 4: Plant the Cuttings

  1. Prepare the Pot: Fill a pot with well-draining soil. Bougainvillea prefers a sandy or loamy soil that drains well to prevent root rot.
  2. Plant the Cuttings: Insert the treated cuttings into the soil, burying the lower nodes. Space them out to ensure they have room to grow.
  3. Water Thoroughly: Water the soil thoroughly to settle it around the cuttings and provide initial moisture.

Step 5: Create a Humid Environment

  1. Cover with Plastic Bag: Place a clear plastic bag over the pot to create a mini greenhouse effect, which will help retain humidity and warmth.
  2. Place in Indirect Sunlight: Put the pot in a location with bright, indirect sunlight. Avoid direct sunlight as it can be too intense for the cuttings.

Step 6: Monitor and Maintain

  1. Check Moisture Levels: Keep the soil consistently moist but not waterlogged. Water the cuttings regularly to maintain moisture.
  2. Ventilate Occasionally: Remove the plastic bag for a few hours every couple of days to allow fresh air circulation and prevent mold growth.

Step 7: Transplanting

  1. Root Development: After a few weeks, the cuttings should begin to develop roots. You can check for root growth by gently tugging on the cuttings; if you feel resistance, roots have formed.
  2. Transplant to Larger Pots: Once the cuttings have established strong roots, transplant them to larger pots or directly into your garden. Ensure they receive adequate sunlight and water to continue growing.


Growing bougainvillea from cuttings using bananas and onions is a natural and effective method to propagate this beautiful plant. By following these steps, you can successfully cultivate bougainvillea and enjoy its vibrant colors in your garden. With patience and care, your bougainvillea cuttings will thrive and add a touch of tropical beauty to your outdoor space. Happy gardening!
