Browning leaves

  • Browning leaves can occur due to a lack of water. Even if you are watering daily or close to every day, depending on temperature, your lemongrass might require more water.
  • A mulch bed is a great way to retain moisture and prevent evaporation.


  • Rust is a fungus that can live and thrive off your lemongrass plants. If left untreated, rust will end up killing your lemongrass plants.
  • Rust occurs when accumulated water droplets rest on the plant for an extended time. Then, the fungus starts to grow in these droplets and slowly overtakes the plant.
  • To avoid rust altogether, one should water the base of the plant. Doing so avoids watering the leaves and leaving those pesky droplets.
  • If you notice rust on your lemongrass plant, you can start trimming the leaves back that contain rust spots. Separation of the infected from the rest of the plant gives it a chance to rejuvenate.

Red Leaf Spot

  • Red leaf spots are reddish-brown bruises that you can find on your plant. Red leaf spots are more prominent in tropical areas, so it’s an unlikely problem in the United States.
  • To lessen the damage from red leaf spots, you should ensure your plants are well-spaced and properly irrigated.
  • If your lemongrass falls to the red leaf spot, you can treat the spots with fungicide.

  • You’ll know you have spider mites if you notice light-colored specks on your leaves. Spider mites will also cause damage as leaves will turn brown and eventually die.
  • Be vigilant as soon as you notice any damage, as these mites reproduce fast!
  • You can get rid of them by washing them off with water or investing in an insecticidal soap that will be gentle on the plant but harder on the pests.
