After you have prepared the corms and constructed a macro-propagation chamber, it is time to plant the corms so that you can get the banana plantlets for your farm.

How to plant banana corms in the macro-propagation chamber

  • Water the macro-propagation chamber to keep it humid. Six drums of 200 litres will be enough for a 3 m long  X 1.5 m wide X 1 m high ma-cropropagation chamber
  • A well watered macro-propagation chamber should be misty. If not misty, add more water
  • Make a hole using your hands and plant the banana corms at 5 cm spacing from each other

  • Cover the macro-propagation chamber with a plastic paper to keep it humid
  • Water the macro-propagation chamber every three to five days depending on climatic conditions
  • After 3-4 weeks shoots will start appearing from the banana corms
  • When only 1-2 shoots appear from a corm, cut off the growing plant to allow other buds to develop
  • After 5-6 weeks, shoots that have developed roots and have three standard size leaves are ready for potting
  • Cut the banana plantlet at the point of attachment with the banana corm. Make sure that a small part of the corm remains with the plantlet to supply the nutrients needed
  • The shoots will take about 10 weeks in the macro-propagation chamber to fully develop

How to pot the banana plantlets

  • Construct a shade house of your desired measurements to accommodate your seedlings/plantlets. Usually, a standard seedling shade house is 4 m wide and 2.5 m high. A simple shade house can be covered by dry twigs and leaves
  • Mix 4 spades of top soil with 1 spade of manure (4:1 ratio) in a 5 X 7 cm potting bags
  • Fill ¾ of the pot with compacted soil and the top 1/4 with loose soil for easy planting
  • Plant the plantlets into the tubes/pots
  • Transfer the plantlets into the shade house
  • Water plantlets 3-4 times a week so that the soil in the pots is moist
  • Remove the banana seedlings from the shade house after 2 weeks for hardening. But do not place the under direct sunlight. A tree shade is good enough
  • Continue watering the banana seedlings 4 times a week
  • The plantlets are ready for planting when they have 4-5 leaves. This will be after 3-6 weeks of hardening
Construct a shade house for the seedlings

How to prepare potting mixture

Generally, the banana seedlings will take 10 weeks in the macro-propagation chamber, 2 weeks in the shade house and 3-6 weeks of hardening up. This totals up to 15 -18 weeks before they are ready for planting in the field.

We hope that by now you can macro-propagate bananas successfully in your farm. For additional support, you can watch a video hereYour feedback is important to us; post your comments below or email us at
