Botanical Background & 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 & 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.

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 & 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.
