Lemongrass thrives in warm, sunny spots with room to spread. It’s a clumping grass, so give it space and good drainage to stay happy.

• Sun: Choose a location with full sun (aim for 6+ hours of direct light).
• Soil: Plant in well‑draining, fertile soil. Mixing in compost can help with nutrients and moisture balance.
• Space: Allow at least 18–24 inches between plants so clumps can fill in without crowding.
• Containers: If your winters are cold, consider a large pot with drainage holes so you can move it as seasons change.
• Moisture: Keep soil evenly moist, especially during hot spells, but avoid standing water.

You can shop live plants, seeds, and gardening supplies on Walmart.com, with pickup and delivery options in many areas.

In warm, frost‑free climates, lemongrass can grow year‑round. In colder regions, it’s typically treated as an annual outdoors or brought inside before hard frost. A simple plan can help keep a favorite clump through winter.

1. Dig and pot up: Before first frost, lift a healthy clump and place it in a container with well‑draining potting mix.
2. Provide light and warmth: Keep near a bright window or use supplemental lights. Aim for a consistently warm spot away from cold drafts.
3. Trim and water lightly: Cut back top growth to reduce stress. Water when the top inch of soil feels dry, avoiding soggy conditions.
4. Reacclimate in spring: After frost danger passes, gradually reintroduce the plant to outdoor sun and replant if desired.

Lemongrass can do well indoors with strong light, consistent warmth, and a roomy container. A few basics help it adapt inside.

• Light: Place near a south‑ or west‑facing window. If light is limited, consider a grow light for 12–14 hours daily.
• Container: Use a pot with drainage; wider containers support its clumping habit.
• Soil and water: Choose a well‑draining mix. Water when the top inch feels dry, and empty saucers to prevent soggy roots.
• Humidity and airflow: Moderate humidity and good air circulation can reduce stress indoors.
• Care: Rotate the pot weekly for even growth and trim older leaves as needed to encourage fresh shoots.

Watering needs depend on heat, soil, and whether it’s in the ground or a pot. Consistent moisture supports steady growth, but roots don’t like to sit in water.

• In‑ground plants: Deeply water about 1–2 times per week during warm, dry weather. Adjust frequency after rainfall and as temperatures change.
• Container plants: Pots dry faster. Check soil every 2–3 days and water when the top inch feels dry.
• Drainage: Ensure soil and containers drain well to help prevent root issues.
• Mulch: A light mulch layer can help retain moisture and reduce temperature swings.
• Watch the plant: Limp leaves may indicate thirst, while yellowing and soggy soil can signal overwatering.

Lemongrass has a citrusy aroma that some people use to make outdoor spaces feel less appealing to certain insects. Results can vary with conditions, plant size, and how products are used.

• Mosquitoes and gnats: Lemongrass‑based outdoor sprays and mists are commonly used to help reduce annoyance; always follow label directions.
• Houseflies: Aromatic plants and essential‑oil products may help in seating areas, though consistent application is often needed.
• Rodents: There isn’t strong evidence that lemongrass plants deter rats. Sealing entry points, removing food sources, and general cleanup tend to be more reliable approaches.

Walmart carries live lemongrass plants, seeds, and outdoor repellents. Consider combining plants with labeled products and good yard hygiene for broader pest management.
