Botanical Background and Origin
Citrus aurantiifolia is believed to have originated in Southeast Asia and was later introduced to the Mediterranean and tropical Americas via Arab and European trade routes. This small, fast-fruiting tree belongs to the Rutaceae family and thrives in warm, humid climates. Indoors, it maintains a bushy, upright form and can live for decades when properly maintained. Like other citrus, it contains compounds that may irritate pets if ingested.
How to Care for Citrus 'Green Lime' Indoors
- Light: Requires 6–8 hours of direct sun daily. Supplement with grow lights in darker seasons.
- Placement: South- or west-facing windows are best. Avoid placing near cold drafts.
- Watering: Water when the top 2–3 cm of soil dries. Avoid overwatering and standing water.
- Humidity: Prefers 50–60%. Use a humidifier or group with other plants in dry homes.
- Temperature: Grows best between 20–30 °C. Protect from exposure below 10 °C.
- Soil: Use a well-draining, citrus-specific mix (loam, sand, and compost).
- Repotting: Every 2–3 years, in terracotta or breathable pots with drainage holes.
- Fertilizer: Feed every 4–6 weeks with citrus fertilizer containing magnesium and iron.
- Propagation: Use semi-hardwood cuttings with 2–3 nodes or grow from seed.
- Semi-Hydroponics: Adaptable to LECA with pH 5.5–6.5 and citrus nutrients.
- Pruning: Regular trimming encourages bushy growth and air circulation.
- Pollination: Self-fertile – gently brush flowers for improved fruit set.
Common Growing Issues and Remedies
- Pests: Aphids, spider mites, and scale can be controlled with insecticidal soap or neem oil. Use sticky traps for citrus leaf miners.

- Root Rot: Always use well-draining soil and allow surface to dry between watering.
- Sooty Mold or Mildew: Improve air circulation and clean leaves with soapy water.
- Fruit Drop: Usually caused by sudden stress – avoid temperature swings and dehydration.

Extra Tips for Thriving Growth
- Wipe leaves gently to boost photosynthesis and reduce pest risks.
- If top-heavy, use a small bamboo support or stake for balance.
- Recreate tropical conditions with consistent warmth, light, and light feeding.
Botanical Etymology and Taxonomy
The genus Citrus comes from Latin and Ancient Greek words for aromatic trees. The species name aurantiifolia combines “aurantium” (orange) and “folia” (leaves), referring to its citrus-like foliage. Citrus aurantiifolia was classified by botanists including Swingle and Tanaka in the early 20th century as a distinct lime species rather than a hybrid.
