Sunlight Requirements

Since Lemongrass is a native of tropical regions, the herb loves the hot weather. If your herb garden is not in a place that receives the full sun, make sure your Lemongrass absorbs 6 to 8 hours of sunlight every day.

Water and Air Temperature

Remember that Lemongrass is frost intolerant. The best time to plant the herb is during Spring once cold passes. The ideal water and air temperature for the plant is 65° to 85°F.


The plant usually grows 3 to 5 feet in height. It is best to position your herbs 24 inches apart to ensure your plants will not compete for nutrients.


Most growers prefer planting Lemongrass from cuttings. Growing the herb by seeds can be a little challenging because it will require warm temperatures, which can result in fungal problems. 

Once you notice your plant is roughly a foot tall, you can begin eating your Lemongrass. Be careful when harvesting the lower part of the stalk since it is the delicate part of the plant. 

Fish Types

Perch is one of the best aquaponics fish you can use in your system. This type of fish is vegetarian, and growers can teach the fish to eat pellets. The optimal water temperature for Perch is between 67⁰F to 77⁰F. It prefers a pH range between 6.5 to 8.5. Aside from being a tasteful fish, Perch are exceedingly tolerant types of fish. 



Got Tanks?


Some gardeners experience rust fungus when growing Lemongrass in Aquaponics gardens. Signs your plant is suffering from this disease are streaks on its foliage or brown spots. It is possible to see more than a hundred scattered rust spots on a single leaf.

Common problems growing Lemongrass

When Lemongrass thrives, the root sometimes creates a restrictive clump that is tough to separate. You can use a hatchet or spade to release pieces of roots free and to make sure you have a healthy root system.

Quick Tips

Lastly, consider these quick tips when storing your fresh Lemongrass.

  • You can tightly-wrap and store your top-quality Lemongrass in the refrigerator for about two weeks.
  • Keep in mind that Lemongrass freezes nicely. Though it will lose a bit of its freshness and aroma when frozen for prolonged periods, however, it will retain its pungent flavor.
