Plant identity, types & settings
One plant guide. Clear details underneath.
Lemongrass is the plant identity. Container, landscape, cutting, indoor, hydroponic, and harvest labels describe ways to grow it; they are not additional plant or cultivar names.
Ways to grow it
These are garden or production settings—not cultivar names and not extra plants.
Garden Crop
Keep harvest access open and label the species and intended plant part; culinary, aromatic, and dye uses are not interchangeable.
- Mature size
- 38 × 23 in
- Spacing
- 23 in
- Container
- 10+ gal · 15+ in deep
Indoor Hydroponic Crop
Select compact seed stock, provide active light, and sanitize the recirculating system between crops.
- Mature size
- 29 × 17 in
- Spacing
- 12 in
- Container
- 5+ gal · 15+ in deep
01 · Light & site
Give it the light its growth depends on.
Full sun, with roughly 6 to 8 hours of useful light. Warm soil and frost-free conditions
02 · Water & soil
Keep roots supplied without trapping water.
Keep the active root zone evenly moist while preserving drainage.
- Soil
- Loose, moderately fertile garden soil
- Drainage
- Moist but drained
- pH
- Species-dependent, commonly mildly acidic to neutral
03 · Spacing & roots
Make room for the mature plant.
Space plants about 30 inches apart. Expect a mature plant around 48 inches tall by 36 inches wide.
A branching root system needs the stated depth plus aerated soil around the mature spread.
04 · Start
Begin with the method that protects establishment.
Direct sow or transplant according to crop-specific temperature and root-disturbance guidance.
05 · Care
Support healthy growth through the season.
Support is usually unnecessary. Self-supporting clump; allow room for arching blades.
