  • If you observe that the cardamom leaves are brownish, spray some water but don’t spray water on the roots as it may get rotten.
  • Try to maintain the humidity in the soil and keep it damp and moist. Feed them liquid kelp once every two weeks. Moreover, you can add an adequate amount of water so that plants absorb it properly.
  • Make sure to transplant the seeds for about five to six months when they show four leaves. Make sure to plant these seedlings into a four inches pot that contains the potting soil.

To prevent aphid attacks, you can apply pest control chemicals. In addition to this, rhizomes rot results in chlorosis of the leaves and premature fruit dropping.
