Sunlight
Best production in full sun, but tolerates semi-shade. Aim for at least 6 hours of direct sun daily.
Citrus aurantiifolia 'West Indian'
R350.00
Classic Aromatic Key Lime!
West Indian (Key) lime produces small, round, highly aromatic limes — the classic sharp lime for drinks, ceviche and cooking.
Self-fertile. Best in warm, frost-free or well-protected gardens.
The West Indian Lime (Citrus aurantiifolia), often called Key lime, is the small, round, intensely aromatic lime of Caribbean and Mexican cooking. Fruit is thinner-skinned and more fragrant than large Persian / Bearss-type limes, with a distinctive sharp perfume that transforms drinks, desserts and savoury dishes.
Trees are somewhat thorny and prefer genuine warmth — they are less cold-tolerant than Meyer lemon. In South Africa they do best in frost-free subtropical gardens or in large pots that can be moved under cover for cold snaps.
Self-fertile and productive once happy. Feed and water as for other citrus, with excellent drainage.
Small, round green to yellow-green limes with thin skin, abundant juice and a strong, distinctive lime perfume. Trees are typically thorny.
Main crops through the warmer months; fruit may be present over a long season in warm gardens.
Grafted trees can produce fruit in the first year of planting!
Moderate grower, often kept 2–3.5m with pruning. Thorny — site away from paths if planting in the ground.
Citrus grow exceptionally well in containers. Choose a large pot with excellent drainage, use a bark-based potting mix and position in the warmest, sunniest spot available.
Best production in full sun, but tolerates semi-shade. Aim for at least 6 hours of direct sun daily.
Keep plants consistently moist but avoid overwatering. Water deeply once a week, allowing the top layer of soil to dry slightly between waterings. Container-grown trees may need more frequent watering.
More frost-sensitive than Meyer lemon. Choose a warm microclimate or grow in a movable container in colder areas.
No chilling requirement.
Self-fertile. A single tree will produce fruit without needing a pollinating partner.
Plant in very well-drained, light, aerated soil — clay soils and waterlogging are fatal to citrus. If planting in a pot, use a good quality bark-based potting mix with added river sand and ensure excellent drainage.
Citrus are heavy feeders. Apply a 6:1:5 fertiliser at monthly intervals throughout the growing season. Supplement regularly with magnesium sulphate (Epsom salts) and iron chelates to prevent yellowing.
Keep plants consistently moist but be careful not to overwater. Monitor for aphids, scale, mealybug and citrus psylla — treat with any product containing imidacloprid.
